Image Resizer: Resize Photos Online Without Uploading

Resize a photo or image to an exact width and height in pixels. It works in your browser, so your picture is never uploaded, and you can save it as JPG, PNG or WebP.

How it works

Choose an image and the tool loads it in your browser, draws it onto a canvas at the size you choose, and saves the result in the format you pick. Nothing is uploaded to a server. With “Keep proportions” on, changing the width sets the height automatically so the picture is not stretched. JPG and WebP use the quality slider: lower quality means a smaller file.

JPG does not support transparency, so transparent areas become white when you save as JPG. PNG keeps transparency but files are usually larger.

Tips

  • Reduce large photos before emailing or uploading to a website to save time and data.
  • Keep proportions on to avoid a stretched picture.
  • Use the aspect ratio calculator to work out the matching height for a new width.
  • For the smallest file at the same size, try the image compressor.

Frequently asked questions

Is my image uploaded?

No. Resizing happens in your browser and the file stays on your device.

What size should a website image be?

It depends on where it is shown. Images wider than the space they fill just add file size, so resize to about the largest display width.

Can I resize to an exact size?

Yes. Turn off Keep proportions and enter the width and height. The image may stretch.
