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 utilities.
The pitch is privacy by architecture: every conversion runs inside your browser via WebAssembly. Files never get uploaded, so there is no server to leak them and nothing to delete after you are done.
It is positioned as a replacement for the dozens of ad-laden single-purpose converter sites people resort to, and the entire toolbox is free with no account required.
