I got tired of "free" tools wanting my email or my files, so I built 26 that run entirely in the browser

Every time I needed a quick PDF merge or background removal, the "free" tool either wanted my email, wanted me to sign up, or was quietly uploading my file to a server somewhere.

So I built tools1hub.com, 26 tools across 7 categories (PDF, image, AI, developer/workflow, and a few others) where everything runs entirely client-side in the browser. Nothing you upload ever leaves your device.

No signup, no email wall, no watermark, no daily limits.

Tech-wise:

Next.js with a static export, hosted on Cloudflare Pages
WebAssembly handles the heavy lifting, ffmpeg.wasm for audio conversion, similar client-side approaches for image processing
No backend at all for most tools, since everything runs in the user's browser

A few tools worth trying:

Background remover, full resolution, no upload
PDF merge/split/compress
Bulk QR code generator
Document OCR and scanner

It's a solo project, very much a v1. Would love feedback on what breaks, what's confusing, or what's missing, especially from other devs who've tackled similar client-side/WASM challenges.
