WebP Resizer
Resize
Enter one value and the other follows automatically while locked.
Saves the edited image at its current dimensions. JPG, PNG, and WebP keep their format; other supported inputs download as JPG. Check the downloaded file for final quality.
Your images are processed locally in your browser and never uploaded to any server.
Resize and download one WebP at a time locally, with transparency preserved and adjustable output quality. If the source is larger than its intended display, reducing dimensions can save bytes as well as pixels.
WebP compression does not remove the need to choose suitable dimensions. Scaling an oversized image down before re-encoding can reduce file size, but the saving depends on the content and quality setting. Downscaling also removes source detail, so keep enough pixels for the intended display and retain the original for other uses.
How to use the webp resizer
- Add one WebP image.
- Set new dimensions or a percentage scale, then click Apply resize.
- Choose output quality and inspect the resized preview.
- Click Download to save the WebP. Repeat for another image.
Resize first, then compress
When an image is both too large and too heavy, choose its dimensions first. Scaling a 3200px-wide image proportionally to 800px leaves one sixteenth of the pixels, not one quarter. That can substantially reduce file size, but it does not guarantee one sixteenth of the bytes: content, format and encoding settings still matter.
Click Apply resize before choosing quality for the download. Around 80 is a starting point, not a promise of invisible compression. Lower settings may work for some photographs but can damage textures, text and edges. Inspect the resized result at its intended display size, including transparent outlines.
Frequently asked questions
Does resizing WebP keep its transparency?
Yes. Transparency scales with the color data and is retained in the WebP download. Resampling can change fine edges, so check the result at the target size.
Why resize instead of just compressing?
Compression reduces storage for the same dimensions; downscaling removes pixels. Scaling from 3200px to 800px wide with proportions preserved leaves one sixteenth of the pixels. The byte saving varies, and removed source detail cannot be restored by raising quality.
What quality should I pick when resizing WebP?
Try around 80 as a starting point, then inspect the result. No setting guarantees invisible loss for every image. Increase quality if textures or edges look damaged, or lower it if the smaller file still looks acceptable at its intended display size.
