I’ve been building this on and off for the past year - it started because I got tired of “free” PDF tools that upload your files to who-knows-where or watermark page 2.
Everything runs client-side: a PDF suite (edit/merge/split/sign/OCR), image and audio converters, 200+ calculators, and some AI tools that lean on local models where possible. No accounts, no file size gates, and it works offline once installed (PWA).
The webdev-relevant bits: most of the heavy lifting is WASM (ffmpeg.wasm, tesseract), plus service workers for offline. Honestly the hardest part was memory management on large files in Safari.
Would genuinely like feedback - especially on what tools are missing. If you want to poke at the audio/video side, https://practicalwebtools.com/studio is the fun part.
feedback is don’t use adblock detection. it’s 2026, shared on lemmy, and you claim it’s client side anyway.
There’s this bouncer who won’t let me in because I won’t make myself available to be manipulated by advertising.
