WebP Resizer
Resize
Enter one value and the other follows automatically while locked.
Saves your edited image at its current dimensions, keeping the original file format. The canvas shows exactly what downloads.
Your images are processed locally in your browser and never uploaded to any server.
Resize WebP files locally: transparency preserved, quality controlled, batch supported. Most WebPs come from the web oversized for their actual display; getting them to true dimensions multiplies the format's already-excellent compression.
How to use the webp resizer
- Add your WebP files.
- Set new dimensions or a percentage scale.
- Pick quality for the re-encode (80 is a strong default).
- Download results individually or as a ZIP.
Frequently asked questions
Does resizing WebP keep its transparency?
Yes. Alpha scales together with color data, intact. Combined with WebP's efficient alpha storage, this is the best small-and-transparent pipeline available in a browser.
Why resize instead of just compressing?
Compression squeezes the same pixels; resizing reduces how many pixels there are. If an image is displayed at 800px but stored at 3200px, resizing first saves far more than any quality reduction. Then compress the result.
What quality should I pick when resizing WebP?
80 preserves resampling quality without visible loss. Lower only when every byte counts and the source is photographic. WebP degrades gracefully down to about 60.
