Forty-two tools that run in this tab.

Whichly is a set of small programs for PDFs, images, video and audio, text, code, everyday sums and school geometry. Each one is a page your browser downloads once and then runs on your own machine: you pick a file, the work happens in memory, and the result is saved straight back to your disk.
