Change the pixel dimensions, with an optional aspect-ratio lock.
What is the Resize Image?
BYAFT's Resize Image tool changes the pixel dimensions of a photo, right in your browser. Enter a new width and height — keeping the aspect ratio locked so the image isn't stretched, or unlock it for an exact size — and download the result. Nothing is uploaded; it all happens on your device.
Use it to fit an image to an exact width for a website, shrink a large photo, or prepare a thumbnail.

Frequently asked questions
Is the image resizer free?
Yes. Resizing images with BYAFT is completely free, with no sign-up and no watermark.
Are my images uploaded?
No. Everything runs in your browser; your image is never uploaded to a server.
Will the aspect ratio be kept?
Yes, by default — "Lock aspect ratio" keeps the proportions so the image is not stretched. Turn it off to set width and height independently.
Does resizing reduce quality?
Making an image smaller is clean; enlarging beyond the original size can look soft, since there is no extra detail to add.
