How to Compress WebP Images Further
- 1
Upload your WebP file
Select the WebP image you want to make smaller. The tool reads WebP natively.
- 2
Set your target
The tool targets 500KB by default. For web use, you might want even less. Adjust the quality slider and file size cap to match your needs.
- 3
Export the compressed WebP
Download the re-encoded WebP file. Compare sizes to see how much you saved.
Can You Even Compress WebP Further?
WebP already beats JPG and PNG on file size — that's its entire purpose. Google developed it to be 25-35% smaller than JPG at equivalent quality. So compressing a WebP file that was exported at 80% quality won't yield dramatic savings. But if your WebP was exported at high quality (90%+), there's still meaningful room to shrink it.
The real use case is when you receive WebP files from other sources and need them smaller. Screenshots saved as WebP by Chrome, images downloaded from websites, exports from design tools — these often use higher quality settings than necessary. Dropping from 95% to 80% quality can halve the file size with minimal visible change.
One thing to watch: re-encoding a lossy WebP introduces another generation of compression artifacts, just like re-saving a JPG. If you can access the original source image, compress from that instead of re-compressing the WebP.
Frequently Asked Questions
Is WebP better than JPG for everything?
For web delivery, almost always yes. WebP files are smaller and support both lossy and lossless compression plus transparency. The exception is compatibility: some older image editors and systems don't read WebP. For those cases, JPG remains the safer choice.
Why is my WebP file already so small?
WebP is highly efficient by design. If your file was exported at moderate quality (70-80%), it's already close to the minimum practical size. Pushing further will produce visible artifacts. You might only save another 10-20%.
Can I compress a WebP and keep its transparency?
Yes. WebP supports alpha channels in both lossy and lossless modes. The compressor preserves transparency during re-encoding.
