This page resizes WebP files specifically. The WebP format is decoded, scaled and re-encoded entirely inside your browser, so the file never travels anywhere and the output stays in WebP.
How it works
- Select one or more WebP files.
- Enter the width or height you want, in pixels or as a percentage.
- Keep the aspect ratio locked unless you specifically need to distort the image.
- Download the result as WebP.
Good to know
Resizing a WebP file re-encodes it, which means the compression is applied again. Going down in size usually shrinks the file considerably; going up will make it larger without adding real detail.
Frequently asked questions
Does resizing WebP lose quality?
Scaling down looks clean because you are discarding pixels you no longer need. Scaling up cannot add information, so a WebP enlarged well beyond its original size will look soft.
Can I resize several WebP files at once?
Yes — select as many WebP files as you like and the same dimensions are applied to all of them.
