100% local — files never leave your device

How it works
Upload images.
Enter width and/or height — aspect ratio locks optionally.
Resize and download.
Good to know
Downscaling uses high-quality resampling. Enlarging beyond the original size adds pixels but not detail — the tool won’t pretend otherwise.
Every step runs locally in your browser using Web Workers — your file is never uploaded to any server.
