How to Compress a WebP

  1. Select or drop your image. Click "Select Image" or drag a WebP file onto the drop zone above.
  2. Adjust the quality. Use the quality slider to balance file size and visual sharpness. 80% is a good starting point for most images.
  3. Check the savings. The stats bar shows the original size, the compressed size, and how much space you saved.
  4. Download. Click Download to save the smaller WebP file to your device.

What This Tool Does

This free WebP compressor reduces the file size of images that are already in WebP format. If you have WebP files that are still larger than you'd like, this tool re-encodes them at a quality level you choose, making them lighter for faster page loads and easier sharing.

Everything runs entirely inside your browser. Your images are never uploaded to a server, so your files stay private and the compression happens instantly, even offline.

Compress vs. Convert

This tool is for files that are already WebP and need to be made smaller. If instead you have a JPEG or PNG that you want to turn into WebP, use the JPEG / PNG → WebP converter — it changes the format and reduces the size in one step.

WebP uses lossy compression here, so lowering the quality value reduces the file size but can introduce visible artifacts if pushed too far. For most images, a quality setting between 70% and 85% keeps the result looking clean while still cutting the file size meaningfully.

Frequently Asked Questions

My image is a JPEG or PNG — can I use this tool?

This tool only accepts WebP files. To turn a JPEG or PNG into WebP, use the JPEG / PNG → WebP converter instead, which handles the conversion and compression together.

Does compressing a WebP reduce its quality?

It can, slightly, because this uses lossy compression. At quality settings of 70–85% the difference is usually hard to notice while the file size drops noticeably.

Is transparency preserved?

Yes. If your WebP has a transparent background, the transparency is kept after compression.

Are my images uploaded to a server?

No. All compression happens locally in your browser. Your files never leave your device, which keeps them completely private.
