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

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

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

20. PDF to Word Converter
https://www.vamriko.com/pdf-to-word/index.html
Convert PDF files into editable Word DOCX documents locally.

21. Image Converter

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

Practical Workflows: Combining the Tools
The collection becomes more useful when several tools handle different parts of the same task.

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.
