Original Summary

I know, there are already a hundred document processing sites. Most of them upload your file to their server, do the job, and send it back. For an Aadhaar or a bank statement that always felt weird to me, when a phone can do the work itself. So I built one where nothing leaves your device. No backend, everything runs in the browser tab. Day one humbled me though. I tried splitting a PDF on my Android phone and it took six minutes. On my laptop, about a second. Turned out the PDF engine (qpdf compiled to WebAssembly) was reading the file in approx 1,400 tiny pieces, and on Android every small read from a picked file is slow. The fix was boring: if the file is 128 MB or less, read it into memory once. Same file went from 1.4 s to 0.25 s even on my laptop, so the bug was slowing down everyone. Phones were just louder about it. Since then I've built it for cheap phones first. The size limit depends on your device's memory, the progress bar is real instead of a spinner, and speech to text runs Whisper on your device with no API key. Some honest stuff before someone asks: - The repo looks new because it is, sort of. It started under another name, and I found out other projects already used it. Renamed it twice before landing on Fizzdoc, and moved to a clean repo for the new name. It's a side project, so expect rough edge - Yes, I used AI tools while building it, like most devs do now. The decisions, the bugs and the six minutes of staring at my phone were all mine. - It's slower than a server on old phones (<4gb ram ones). Speech to text works best on clear English (Hinglish is still a comedy show). Same-font PDF editing only works when the font already has those letters. - 64 tools, 16 languages, free, no sign-up, open source (Apache 2.0). Code: https://github.com/kingrishabdugar/fizzdoc Tell me what breaks on your phone. Weird PDFs welcome. if you think it's useful, a star on kingrishabdugar/fizzdoc helps more people find it. It also makes me happy 😊   submitted by   /u/rishabdjain [link]   [comments]
