Resize WebP
Change the width and height of WebP images — private, in your browser
Change the dimensions of a WebP
Sometimes a WebP is simply the wrong size — a 4000px photo where a 1200px version would do, a banner that needs to fit an exact slot, or a thumbnail that has to be uniform across a grid. Resizing changes the pixel dimensions of the image so it fits where it is going, without re-exporting from the original source. This tool does it in the browser with an optional aspect-ratio lock.
Drop a WebP, type the width or height you want, and the locked ratio keeps everything in proportion. Adjust the quality slider if you also want a lighter file, then download the resized WebP — or process a batch and download them together.
How to resize a WebP
- Drop your WebP image into the box above, or click to choose it.
- Enter a new width or height — keep the lock on to preserve the aspect ratio.
- Set the quality slider if you also want to trim the file size.
- Click Download resized WebP, or export a batch as a ZIP.
Why resize WebP images?
Fit any layout
Match a template slot, an upload limit or a thumbnail grid by setting the exact dimensions you need instead of relying on CSS to squeeze the image.
Ship the right number of pixels
Serving a smaller image where a smaller image is shown avoids wasting bandwidth on resolution nobody sees.
Proportions stay intact
The aspect-ratio lock scales width and height together, so nothing looks stretched or squashed.
Frequently Asked Questions
Can I keep the aspect ratio?
Yes. Leave the lock enabled and typing one dimension fills in the other automatically, so the image scales without stretching. Unlock it if you deliberately want to distort or crop to fixed pixels.
Will resizing reduce quality?
Scaling down is clean and usually looks great. Scaling far beyond the original size can look soft, because the tool has to invent pixels that were never captured.
Does resizing also shrink the file?
Usually yes — fewer pixels means fewer bytes. The quality slider lets you trim the file further when you re-encode the resized WebP.
Are my images uploaded?
No. Resizing runs entirely in your browser, so your WebP files stay on your device.
Can I resize several WebP files to the same size?
Yes. Add multiple images, set the dimensions once, and download them all as a ZIP resized with the same settings.
