Toolerax
169 free online tools — PDF, image, text & converters
Toolerax is a free collection of 169 online tools — PDF, image, text, converters, calculators and developer utilities. 101 of the 169 run entirely in the browser using Canvas, WebAssembly and the Web Crypto API, so the file never leaves your device for those. The remaining 68 handle formats a browser genuinely can't process — HEIC, PSD, EPS, legacy Office and OpenDocument formats, OCR — and run server-side in an isolated workspace that's deleted the moment the result returns. No account, no watermark, no daily limit.

Comments
I kept hitting the same wall: needing to merge a PDF or convert a HEIC photo, and every free option online wanted an email address first, added a watermark, or capped me at 3 files a day. Toolerax is the fix — 169 free tools across PDF, image, text, converters, calculators and developer utilities. 101 of them run entirely in the browser (Canvas, WebAssembly, Web Crypto), so the file never leaves your device for those — open the Network tab while a tool runs and you'll see nothing sent. The other 68 need a real desktop engine for formats a browser can't handle (HEIC, PSD, legacy Office files, OCR), so those run server-side and the file is deleted the moment the result comes back. Built and run solo out of Dhaka, Bangladesh. Happy to answer anything about the stack or which tool to add next.
