Free tools

Small tools that keep your work on your machine

Every tool on this page runs inside the browser tab you are reading it in. Whatever you paste or drop in stays on your machine: there is no upload step, no account, and no server to send it to in the first place.

That matters more than it sounds like it should. People diff config files, decode tokens and clean up spreadsheets on sites that quietly keep a copy of all of it. These do not, and they are free because they cost nothing to run.

Not every image job can run in a browser. The HEIC and RAW ones cannot, because the decoders are either missing from most browsers or far too big to send you, so those three hand off to the Mac app instead. All twelve image pages, the ones carded above included, live on the Images side.
