About ZumaTools

ZumaTools is a small collection of image tools that run entirely in your browser: compressing, resizing and converting JPG, PNG and WebP files.

Most online image tools upload your files to a server, process them there, and send them back. That is slow, and it means your images pass through someone else's computer. Modern browsers can do all of this work locally — so that is how these tools are built. Nothing you drop on this site ever leaves your device.

The tools are free, have no file limits, add no watermarks and require no account. The site is funded by unobtrusive advertising.
