Resize Image Online

Resize image dimensions locally in your browser. Change the long edge, width, height, output format, or quality to reduce file size before download.

This page is designed for practical size reduction. If you want a metadata-only cleanup without changing dimensions, use the strip or optimize tools instead.

Your image stays on your device. exif.tools performs the resize locally in your browser and does not upload the file to our server.

How This Resize Tool Works

The resize page uses browser-native image decode, scaling, and re-encode paths. That keeps the workflow local and responsive while still working across modern browsers.

For very large images, the page tries to use a downscaled decode path first to reduce peak memory use before drawing to canvas. Animated image formats are treated as a single-frame resize in this browser workflow.
