Runs in your browser — your files and text stay on your device
Change an image's dimensions, compress it, or convert its format in your browser. Resizing to the size you actually need makes photos load faster and fit upload limits, and because it runs locally your photos are never uploaded. Scale down rather than up for the sharpest result.

Frequently asked questions
Which format gives the smallest file size?
WebP usually compresses smallest at a given quality, followed by JPEG. PNG is lossless, so use it only when you need transparency or exact pixel fidelity.
Is my image uploaded anywhere?
No. Resizing and compression happen entirely in your browser using the Canvas API.
