Original Summary

Most "free online PDF tools" make you upload your contract, bank statement or ID to their server. I wanted to see if that step was still necessary in 2026. Turns out it mostly isn't. InstantTools (instanttools.org) runs PDF merge/split/compress/redact, video trimming and conversion, OCR, image compression, EXIF removal and a bunch of dev utilities entirely client-side, using pdf-lib, qpdf, ffmpeg.wasm and Tesseract.js compiled to WebAssembly. What I learned building it: - ffmpeg.wasm works great for short clips, but single-threaded encoding is slow for long or 4K video - Browser memory is the real file-size limit, not bandwidth - Some tools are reduced in scope compared to server-based versions (e.g. background removal is color-based, not AI), so I label those Beta It's free, no account needed. I'm a solo dev and the site is only a few months old, so honest feedback is very welcome: what's broken, what's confusing, what tool you wish existed.   submitted by   /u/dr_Ithan [link]   [comments]
