About Image Resizer

Image Resizer changes the dimensions of a picture. Type a new width or height in pixels, pick a percentage such as 50 percent or 200 percent, or start from a social media preset for Instagram, YouTube or X. With the aspect ratio lock on, the other side adjusts automatically so the image is not stretched.

Choose PNG, JPG or WebP as the output and download the result in one click. The resizing is done on a canvas in your browser, so the original image is not uploaded.

Common ways to use it

  • Make a profile picture or cover image fit a social network's size requirements.
  • Scale down large camera photos before putting them on a website.
  • Enlarge or shrink a graphic to an exact pixel size required by a form.

Image Resizer FAQ

How do I avoid a stretched image?

Keep the lock aspect ratio option on. When you change one dimension, the other updates to keep the original proportions.

Can I change the file format while resizing?

Yes. You can download the resized image as PNG, JPG or WebP.

Does making an image larger improve it?

No. Enlarging adds pixels but not detail, so a very small image will look soft when scaled up a lot.
