Resize images online, privately.
Set exact dimensions, crop to an aspect ratio, rotate, or flip, with a live preview as you go. Need a whole folder at web size? Batch resize fits every image inside a box you choose. It all runs on your device.

How it works.
Three steps, no setup, nothing uploaded.
Drop your image
Or drop several at once to resize a whole set in one go.
Set the geometry
Type exact width and height with an optional aspect-ratio lock, crop with presets (1:1, 4:5, 16:9 and more), rotate in 90° steps, or flip. The preview updates live as you work.
Download the result
A single file downloads directly. A batch downloads as a zip with every image fitted to your chosen box.
Questions.
Can I resize a batch of images to the same size?
Yes. Drop several images, choose Resize, and fit them all within a width × height box (aspect ratio kept, never enlarged) or scale them by a percentage. Results download as a zip.
Does resizing keep the aspect ratio?
You choose. Lock the aspect ratio to scale proportionally, or unlock it to set an exact width and height independently.
Does resizing lose quality?
Scaling down keeps images crisp. It is mathematically the safe direction. Scaling up with a plain resize will soften; if you need a bigger image, the AI Upscale tool rebuilds detail instead of stretching pixels.
Can I crop for Instagram, YouTube, or a header?
The crop presets cover the common ratios: square 1:1, portrait 4:5, story 9:16, widescreen 16:9. And you can type exact pixel dimensions for anything else, like banner sizes.
Are my images uploaded anywhere?
No. Resizing uses your browser’s canvas. The image is decoded, transformed, and re-encoded entirely on your device.
