Images are almost always the heaviest thing on a page, in an email, or in a form upload — and almost always heavier than they need to be. This compressor re-encodes your image at the sweet spot where file size drops dramatically before quality visibly does. PNGs with transparency come back as lossless-looking WebP; photos come back as tuned JPEGs.
Everything runs in your browser: batch-drop fifty images and they're processed on your own hardware, in parallel with nothing waiting in anyone's queue.
Free, private, no upload. Ever.
This tool runs entirely on your device. It's built by the team behind RenameTo for Mac — where the same job is just a rename in Finder.
