As developers, we constantly need small utilities — converting files, compressing images, generating QR codes, editing PDFs. Instead of installing desktop apps or trusting random websites, I've been using Tools1984 — a platform with 2300+ free online tools. Here are my top picks:
1. PDF Editor & Merger
Need to merge multiple PDFs before sending documentation? Or split a large PDF into sections? Tools1984's PDF suite handles merging, splitting, compressing, and rearranging pages — all in the browser.
Use case: Combining API docs, contracts, or reports into a single file.
2. Image Compression
Optimizing images for web performance is crucial. The image compressor supports JPG, PNG, WEBP, and GIF formats with adjustable quality settings.
Use case: Compressing screenshots and assets before pushing to your repo or deploying your site.
3. QR Code Generator
Generate QR codes for WiFi networks, URLs, WhatsApp links, VCards, and UTM-tagged campaigns. Useful for both development testing and production.
Use case: Creating WiFi QR codes for your office, or deep link QR codes for mobile app testing.
4. File Converters
With 100+ format conversions available, you can convert between document, image, video, and audio formats without installing ffmpeg or ImageMagick locally.
Use case: Quick format conversions during development without CLI setup.
5. Base64 Encoder/Decoder
Encode and decode Base64 strings instantly. Handy for working with APIs, JWTs, and embedded data.
Use case: Debugging base64-encoded payloads in API responses.
6. JSON Formatter & Validator
Paste messy JSON and get it formatted and validated instantly. Saves time compared to manual formatting.
Use case: Formatting API response payloads for documentation or debugging.
7. Hash Generator (MD5, SHA-256)
Generate hashes for file integrity checks, password hashing tests, or checksum verification.
Use case: Verifying file downloads or testing hash implementations.
