Resize
Resize images with exact dimensions, fit-within-box, or percent scaling.
About Resize
Resize scales JPEG, PNG, and WebP images to exact dimensions, to fit within a bounding box, or by a percentage. It is the go-to for hitting an upload limit, producing consistent thumbnails, or downsizing camera shots for the web. All scaling happens in your browser — your images stay on your device.

Frequently asked questions
What resize modes are available?
Three: exact dimensions (set a precise width and height), fit-within-box (scale down to fit a bounding box while preserving aspect ratio), and percent scaling (resize by a percentage of the original).
Will resizing distort my image?
Exact-dimension mode can stretch an image if the new ratio differs from the original. Fit-within-box and percent modes preserve the aspect ratio so the image stays proportional.
Which formats does it accept?
JPEG, PNG, and WebP. The output keeps the same format as the input.
Are my images uploaded?
No. Resizing is done entirely in your browser, so the image never leaves your machine.
Does enlarging an image add real detail?
No. Upscaling stretches existing pixels and cannot invent new detail. For AI-assisted enlargement that sharpens edges, see the upscale tools.
