Worked example

Halving a 4K photo

We resized a 3840 x 2400 photo to 50 percent with the aspect ratio locked. The browser made a 1920 x 1200 JPG of 94,237 bytes in 25 milliseconds, and the photo never left the device.

Measured on 19 October 2026 by running this page's in-browser engine on our own test files.

What it does not do

It does not add detail when you enlarge: making a small image bigger cannot recover pixels that were never captured.

Common questions

Is my image uploaded?+

For JPG, PNG and WebP, no. The resize happens entirely in your browser on a canvas, so the image never leaves your device. (Unusual formats the browser can't open are processed privately on our engine and deleted after 1 hour.)

Will it stay sharp?+

We use high-quality smoothing when scaling. Making an image smaller stays crisp; enlarging a small image can only do so much. There's no detail to invent without AI upscaling.

Can I keep the aspect ratio?+

Yes. The lock is on by default, so changing the width updates the height automatically. Unlock it to set an exact width and height.

Is there a limit, watermark or signup?+

No watermark and no signup. Images the browser can resize never upload and are never counted; anything that runs on our engine is on the server plan. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.

Can I resize an image for free?+

Yes. JPG, PNG and WebP images are resized in your browser: they are never uploaded and never counted, with no watermark and no signup.

Can I resize several images for free?+

Yes, one after another: this page resizes one image at a time. Each one is free and stays on your device.
