TabTasker
Privacy-first browser toolbox for PDFs, images, audio, and code
Visit website →About
TabTasker bundles dozens of everyday file utilities into a single browser tab: PDF merging and OCR, image upscaling and background removal, audio transcription and noise reduction, plus a long list of developer and text tools.
The design is privacy by architecture, every conversion runs inside the browser via WebAssembly. Files are never uploaded, so there is no server to leak them and nothing to delete afterward.
It is positioned as a replacement for the many ad-laden single-purpose converter sites people fall back on, and the whole toolbox is free with no account required. It is aimed at anyone who regularly needs quick file conversions and wants them done locally.

Why we picked it
TabTasker's privacy-by-architecture design sets it apart from cloud file utilities: every PDF merge, image upscale, or audio transcription runs inside the browser itself via WebAssembly, so files never leave your machine at all.
