Exact pixel output

The resized image is rendered to precisely the requested width and height using high-quality canvas resampling. What you download matches the pixels you asked for.

Aspect ratio control

Set both width and height for exact dimensions, or set one side and the tool keeps the original aspect ratio for the other.

Private by design

Your image is decoded, resized and encoded entirely in the browser — nothing is uploaded.

Frequently asked questions

Does it keep my files private?

Yes. All decoding, resizing and encoding happen in your browser; nothing is uploaded.

Can I keep the aspect ratio?

Yes. Leave one dimension empty and the other side is derived from the original ratio.

What formats can I output?

JPEG or PNG. Choose JPEG for photos and PNG for images that need transparency or crisp edges.
