Precise control
Enter a width and height; with the ratio locked, the other value is computed automatically.
Resize Image
Set a new width and height in pixels. Lock the aspect ratio to avoid distortion — processing is local, with no upload.
Same format
The result is saved in the same format as the original (PNG/JPG/WebP).
In your browser
The image is never uploaded — resizing is local.
Frequently asked questions
Is my image uploaded?
No. Resizing runs entirely in your browser — the image stays on your device.
What does “Lock aspect ratio” do?
When on, changing the width recomputes the height automatically (and vice versa) so the image isn’t distorted.
Can I enlarge an image?
Yes, but scaling beyond the original size makes it softer — pixels are interpolated, no real detail is added.
What format is it saved in?
The same as the original if it’s PNG, JPG or WebP; otherwise PNG.
