Image Resizer

Resize JPG, PNG, WEBP or HEIC images to exact pixel dimensions, keep the aspect ratio, batch process. Runs in your browser; nothing is uploaded.

🔒 Your files never leave your device. Conversion runs entirely in your browser — nothing is uploaded to any server.

Resize to exact dimensions

Enter a width, a height or both. With Keep aspect ratio on, the image is scaled to fit inside the box you set without distortion. Turn it off to force exact dimensions (the image is stretched).

FAQ

Can I enlarge an image?

Yes, but enlarging can't add detail, so the result looks softer.

Is anything uploaded?

No—resizing uses your browser's canvas, locally.
