About resizing images here

If you shrink a photo in one big jump, it can turn muddy. This tool shrinks in several small steps instead, so edges and text stay sharp.

You can also make images bigger, but no tool can invent detail. Bigger versions will look a little soft.

Like everything on this site, this tool runs in your browser. Your image is never uploaded.

Common questions

Is the resize tool free?

Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.

Are my files uploaded to a server?

No. The resize tool runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.

Will resizing make my image blurry?

Making an image smaller keeps it sharp, and the sharpen tool will bring back any crispness the shrinking softened. Making it bigger is the problem, because the extra pixels have to be invented from the ones already there, so the result looks soft no matter what tool you use. Always resize down from the largest original you have.

How do I resize an image without stretching it?

Leave the lock on. With the lock closed you type one measurement and the other follows automatically, which keeps the original proportions and stops anything looking squashed. Turn the lock off only when something demands an exact width and height that don't match the shape of your picture, and expect distortion when you do.
