41 Free Online Tools for Images, PDFs, Video, Audio, and Everyday Work

I’m building Vamriko, a collection of free online tools for everyday digital tasks.

https://www.vamriko.com/

Alongside the developer tools collection, I’ve been working on utilities for images, PDF documents, file conversion, video, audio, writing, and everyday calculations.

This guide introduces 41 tools across eight categories: what they do, when you might use them, and how several of them can fit into the same workflow.

If you need to prepare an image, organize a PDF, extract audio, or handle a quick calculation, the goal is to help you find the right tool without searching through unrelated applications.

1. Image Tools — 10 Utilities

These tools cover image preparation, editing, optimization, and text extraction.

1. Image Compressor

https://www.vamriko.com/image-compressor/index.html

Reduce image file size with adjustable JPG and WebP quality settings. Supported input formats include JPG, PNG, and WebP.

Use it to prepare screenshots, blog illustrations, or other website images. Compare the compressed result with the original, especially around small text and detailed edges.

2. Image Resizer

https://www.vamriko.com/image-resizer/index.html

Resize images to specific dimensions.

This is useful when a picture needs to fit a particular layout, such as a blog illustration or product image. Resizing changes image dimensions, while compression addresses file size; some tasks benefit from both.

3. Social Media Image Studio

https://www.vamriko.com/social-media-image-studio/index.html

Resize, crop, and export an image for platforms including YouTube, Instagram, TikTok, Facebook, LinkedIn, X, and Pinterest.

Use it to adapt the same visual for different publishing destinations. Review each crop to keep important text and subjects within the visible area.

4. Image to Text — OCR

https://www.vamriko.com/image-to-text/index.html

Extract Arabic and English text from images.

Use it to turn a screenshot or photographed passage into editable text. Proofread the output, particularly names, numbers, and punctuation.

5. Image Watermark Tool

https://www.vamriko.com/image-watermark/index.html

Add a visible text watermark to an image.

Place a name, website address, or label on a picture before sharing it. Check the placement and size so the watermark does not obscure the content.

6. Background Remover

https://www.vamriko.com/background-remover/index.html

Remove a simple solid-color background locally.

This tool focuses on straightforward backgrounds. It is not presented as a universal solution for removing complex photographic backgrounds.

7. Image Upscaler

https://www.vamriko.com/image-upscaler/index.html

Increase image dimensions locally by up to four times.

Use it when you need a larger image output. Inspect the result at its intended display size, since increasing dimensions does not necessarily restore missing detail.

8. Favicon Generator

https://www.vamriko.com/favicon-generator/index.html

Generate favicon assets from an image.

This is useful when preparing a website’s visual identity. Start with a simple, recognizable graphic and check how it looks at small sizes.

9. Image Cropper

https://www.vamriko.com/image-cropper/index.html

Crop an image and download the result.

Remove unwanted edges, focus on a subject, or refine the composition before resizing or publishing.

10. Image Metadata Remover

https://www.vamriko.com/image-metadata-remover/index.html

Inspect image tags and remove supported EXIF, GPS, and text metadata locally.

Verify the result before downloading. Supported metadata removal should not be interpreted as a guarantee that every possible metadata field in every file format is handled.

2. PDF Tools — 10 Utilities

These tools help combine documents, organize pages, convert formats, and prepare PDFs for sharing.

11. PDF Merger

https://www.vamriko.com/merge-pdf/index.html

Combine multiple PDF files into one document.

Use it to bring together a report and its supporting documents, for example. Check the final page order before sharing the merged file.

12. PDF Watermark

https://www.vamriko.com/pdf-watermark/index.html

Add text or logo watermarks to PDF pages locally.

Label a document as a draft or add visible branding. Review the output to make sure the watermark does not interfere with readability.

13. Add Page Numbers to PDF

https://www.vamriko.com/add-page-numbers-pdf/index.html

Add custom page numbers to a PDF locally.

This is particularly useful after combining several documents. Finalize the page sequence first, then add numbering.

14. Organize PDF Pages

https://www.vamriko.com/organize-pdf/index.html

Reorder, rotate, and delete PDF pages locally.

Use it to remove unnecessary pages, correct incorrectly oriented scans, or rearrange sections into a more useful order.

15. Rotate PDF

https://www.vamriko.com/rotate-pdf/index.html

Fix PDF page orientation and download the result locally.

Choose this focused tool when the main issue is a sideways page rather than the structure of the entire document.

16. JPG & PNG to PDF Converter

https://www.vamriko.com/image-to-pdf/index.html

Turn images into a downloadable PDF.

For example, collect photographed notes or scanned images into one document. Review the image order and readability in the exported PDF.

17. PDF to JPG Converter

https://www.vamriko.com/pdf-to-jpg/index.html

Convert PDF pages into JPG or PNG images.

Use it when you need a page as an image for a presentation, illustration, or workflow that does not accept PDF files.

18. PDF Splitter

https://www.vamriko.com/split-pdf/index.html

Split a PDF into individual pages or selected page ranges.

Extract the relevant section of a larger document instead of sending the entire file.

19. PDF Compressor

https://www.vamriko.com/pdf-compress/index.html

Reduce PDF file size locally.

Use it when preparing a document for a file-size limit. Compare both output size and readability before choosing the compressed version.

20. PDF to Word Converter

https://www.vamriko.com/pdf-to-word/index.html

Convert PDF files into editable Word DOCX documents locally.

Use the result as a starting point for revisions. Review the converted text, layout, and formatting before continuing your edits.

3. Conversion and Photo Preparation — 4 Utilities

This section covers image format conversion and printable identity-photo layouts.

21. Image Converter

https://www.vamriko.com/image-converter/index.html

Convert images between JPG, PNG, and WebP.

Use it when a publishing destination or editing workflow requires a particular image format. Check the exported result before replacing your original.

22. Passport Photos

https://www.vamriko.com/passport-photo-maker/index.html

Create passport, visa, and ID photo layouts using supported sizes, with printable A4 PDF output.

The tool helps with sizing and layout preparation. Check the current requirements of the relevant passport office, embassy, or other authority before submitting a photo. A prepared layout does not guarantee official acceptance.

23. HEIC to JPG Converter

https://www.vamriko.com/heic-to-jpg/index.html

Convert supported HEIC and HEIF photos to JPG locally.

Adjust JPEG quality and preview the result before downloading. This is useful when a destination accepts JPG but does not support the original photo format.

24. SVG to PNG Converter

https://www.vamriko.com/svg-to-png/index.html

Convert SVG files into PNG images directly in the browser.

Use it when you have an SVG graphic but need a PNG for a particular publishing or editing workflow.

4. Video Tools — 3 Utilities

These tools focus on common video preparation tasks.

25. Video Compressor

https://www.vamriko.com/video-compressor/index.html

Compress supported videos locally to MP4.

Adjust quality, resolution, and frame rate, and choose whether to keep or remove audio. Compare the output file size and visual quality to find a suitable balance.

26. Video Trimmer

https://www.vamriko.com/video-trimmer/index.html

Trim MP4 videos to keep the section you need.

Remove an unnecessary opening or ending, or prepare a shorter clip from a longer recording. Preview the beginning and end of the exported result.

27. Video to MP3 Converter

https://www.vamriko.com/video-to-mp3/index.html

Extract audio from a video locally.

Use it when you need the audio portion of your own recording without retaining the video.

5. Text and Writing Tools — 5 Utilities

These tools cover resume creation, dictation, text measurement, speech playback, and decorative text.

28. Resume Builder

https://www.vamriko.com/resume-builder/index.html

Create a resume using 20 customizable templates and download it as a PDF.

Organize your experience, skills, and education into a document you can review and share. Check the final PDF for layout issues and spelling mistakes.

29. Speech to Text Converter

https://www.vamriko.com/voice-typer/index.html

Dictate speech into text in the browser.

Use it to draft notes or capture an initial version of an idea. Review the transcription before treating it as finished writing.

30. Word Counter

https://www.vamriko.com/word-counter/index.html

Count words and characters, and view an estimated reading time.

Use it when preparing an article, editing a short description, or checking text against a length requirement.

31. Text to Speech

https://www.vamriko.com/text-to-speech/index.html

Convert written text to speech in the browser.

One practical use is listening back to a draft as part of your editing process.

32. Fancy Text Generator

https://www.vamriko.com/fancy-text-generator/index.html

Create decorative Unicode text, including cursive, bold-style, gothic, and other letter styles that you can copy and paste.

Use it for short decorative elements. Check how the result appears in the application or website where you plan to publish it.

6. Audio Tools — 3 Utilities

These tools cover trimming, format conversion, and combining audio.

33. Audio Cutter

https://www.vamriko.com/audio-cutter/index.html

Trim and convert audio locally.

Isolate a useful section of a recording or remove unwanted material from the beginning or end.

34. Audio to WAV Converter

https://www.vamriko.com/audio-converter/index.html

Convert supported audio files into WAV locally in the browser.

Use it when the next step in your workflow requires a WAV file rather than the original format.

35. Audio Joiner

https://www.vamriko.com/audio-joiner/index.html

Arrange, preview, and merge audio files locally.

Combine several audio segments into one sequence. Check their order and listen to the transitions before downloading the result.

7. QR Codes and Barcodes — 2 Utilities

These tools help create shareable codes and barcode outputs.

36. QR Code Generator & Scanner

https://www.vamriko.com/qr-code-generator/index.html

Create, customize, download, and scan QR codes directly in the browser.

For example, prepare a QR code for a website address. Test the exported code before placing it on a printed design or publishing it.

37. Barcode Generator

https://www.vamriko.com/barcode-generator/index.html

Create EAN, UPC, and Code 128 barcodes.

Download options include PNG, SVG, JPG, and PDF. Barcode batches can also be exported as ZIP files.

Choose the format required by your workflow and verify the encoded value before using the output.

8. Security and Everyday Calculations — 4 Utilities

The final section covers password generation and practical calculations.

38. Password Generator

https://www.vamriko.com/password-generator/index.html

Use it when you need a newly generated password rather than inventing one manually. Never include real passwords in public feedback or screenshots.

39. Loan Calculator

https://www.vamriko.com/loan-calculator/index.html

Calculate monthly payments and interest.

Explore different borrowing scenarios by changing your inputs. Treat the result as an estimate based on those inputs, not as a lender’s final offer.

40. Scientific Calculator

https://www.vamriko.com/scientific-calculator/index.html

Perform advanced mathematical calculations in the browser.

Use it when your task needs more than basic arithmetic.

41. Currency Converter

https://www.vamriko.com/currency-converter/index.html

Convert currencies using the latest available exchange rates provided by the tool.

Use it for indicative comparisons. Confirm the actual exchange rate and any fees with your payment provider before making a transaction.

Practical Workflows: Combining the Tools

The collection becomes more useful when several tools handle different parts of the same task.

Prepare an Image for a Blog Post

Use Image Cropper to refine the composition.
Resize the image to the dimensions your layout needs.
Compress it if the exported file is still too large.
Inspect the final image before publishing.

Convert relevant images into a PDF.
Merge it with your existing PDF documents.
Reorder or rotate pages using Organize PDF Pages.
Add page numbers after the sequence is final.
Check readability and page order before sharing.

Reuse Audio From Your Own Video

Extract its audio using Video to MP3.
Use Audio Cutter if you need a shorter selection.
Convert to WAV if your next editing step requires it.

Prepare a Social Media Image

Choose a crop and output layout in Social Media Image Studio.
Add a text watermark if needed.
Check the final dimensions and file size.
Preview the image before posting.

Processing, Privacy, and Output Checks

Several tools in this collection are described as processing files locally. That should not be interpreted as a promise that every feature works offline or that the entire website makes no network requests.

Check the instructions on the individual tool page, especially before working with sensitive files.

For any conversion or editing task:

Keep a separate copy of the original.
Start with a small sample when trying an unfamiliar tool.
Check that your input format is supported.
Review the output before sharing or replacing your source file.
Do not include confidential documents or credentials in public issue reports.

I’m continuing to improve Vamriko and would appreciate specific feedback from people trying the tools.

Which tool would you use, and what would make it more useful?

If something does not work as expected, sharing the tool name, browser, and steps to reproduce the issue—without including confidential files—would help me investigate.

91 Free Developer Tools to Simplify Your Daily Workflow

wael Boshra — Sun, 18 Oct 2026 13:23:09 +0000

As developers, we often need quick tools for formatting JSON, encoding and decoding data, inspecting tokens, working with SQL, and handling everyday development tasks.

Instead of installing a separate application for every small job, having a collection of handy web tools can save time during development.

A Collection of Free Online Developer Tools

I've been building Vamriko, a website that brings together useful online tools for developers and everyday tasks.

The developer tools collection includes utilities for working with:

JSON and data formats — format and inspect structured data.
Encoding and decoding — handle common data transformation tasks.
JWT and security utilities — work with tokens and related development tasks.
SQL and development utilities — simplify common coding workflows.
Networking and DevOps — access practical utilities for technical tasks.

The goal is to make these tools easy to access directly from a browser when you need them.

Try the tools

Explore the developer tools here:

I'd love to hear from other developers:

Which small development task do you find yourself repeating most often, and what tool do you use to handle it?

I'm continuing to improve the collection and would appreciate constructive feedback.

Disclosure: I'm the creator of Vamriko, and I'm sharing this project transparently.
