Resize an image

Change the width and height of your images, one or a whole batch, keeping their shape.

Your files never leave your device. Everything happens in this browser tab. Nothing is uploaded, and closing the tab erases it.

How it works

  1. Drop your images, or choose them.
  2. Type the width or height in pixels, or a percent. The shape stays the same unless you untick it.
  3. Download them one by one, or all together as a ZIP.

Questions

Are my images uploaded anywhere?

No. The conversion runs inside your browser, on your device, so nothing leaves it: you can check by turning off Wi-Fi once the page has loaded.

How many can I convert at once?

There is no limit on the number of files and no daily limit. They convert one at a time on your own device, so a big batch takes longer on an old phone.

Will a bigger size look sharper?

No. Making a picture bigger spreads the same detail over more pixels, so it looks softer. Making it smaller stays sharp.

What format comes out?

A PNG stays a PNG, with its transparency. Everything else comes out as a JPG.

I need a certain file size, not a certain width.

Use Compress image: you type the size in KB.
