About CogHut

CogHut is a collection of small, focused tools for everyday file tasks: making images smaller, changing formats, and creating things like QR codes. Each tool does one job and tries to do it well.

How the tools work

All processing happens inside your web browser using standard web technologies such as the Canvas API. When you choose a file, it is read into your device's memory, processed there, and offered back to you as a download. Your files are not uploaded to our servers, which also means the tools keep working on slow connections once the page has loaded.

Free to use

The site is free and is supported by advertising. Ads never have access to the files you process.
