Resize Images Online And Reduce File Size
Resize image dimensions online while keeping processing in your browser. Change width, height, long edge, 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.
Resize Image
Choose an image, then adjust the output settings. The resize runs automatically after upload and while you change the controls. Browse, drag and drop, or paste an image anywhere on the page.

How The Online Image Resizer 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.
