How to use Resize Image

Will my image be stretched?

Not if “Keep aspect ratio” is on — the other side is calculated automatically.

Can I make an image bigger?

Yes, but enlarging cannot add detail, so it may look soft.

Is Resize Image free?

Yes. Resize Image is completely free, with no sign-up, no watermark and no usage limits.

Is my data uploaded to a server?

No. Resize Image runs entirely in your browser. Your files and text never leave your device.

Does it work offline?

Yes. After Red Cat Tools has loaded once, this tool keeps working without an internet connection. You can also install Red Cat Tools as an app.

Crop freely or to 1:1, 4:3, 16:9 and more.

Make JPG, PNG and WebP files smaller in bulk.

Convert between JPG, PNG, WebP — and from HEIC.

Pick colors and extract a palette from any image.

Create favicons and app icons from an image or text.

See and strip hidden GPS and camera metadata.
