WebP compression method
Choose the right WebP compression method

- This page accepts WebP images only. It does not convert JPEG or PNG files to WebP.
- A local batch can contain up to 10 images to keep memory usage predictable.
- WebP compression is quality-based in the current interface. Use the image file size compressor or fixed-KB tools when you need a target size.
- Reducing WebP file size can change fine detail, gradients, or small text, so review important files before publishing.

Questions, answered
WebP compressor FAQ
How do I compress WebP images online?
Add WebP images, adjust the compression quality, then download the optimized results. The public workflow runs in your browser by default.
Is this WebP compressor free?
Yes. The WebP compressor is free to use in the current public release, with no account required for local WebP compression.
Are my WebP images uploaded?
No. The public workflow is designed to process selected WebP files locally in your browser by default.
Can I reduce WebP file size without changing dimensions?
The default path adjusts compression quality and keeps the image dimensions. Dimensions can change only if you choose resize options in the custom settings.
Why did my WebP image not get much smaller?
WebP files are often already efficient. If a file has already been compressed strongly, there may be less room to shrink it without visible changes.
Can I compress multiple WebP files at once?
Yes. You can add a local batch of WebP files, review each completed result, and download the optimized copies.
Does this tool convert JPEG or PNG to WebP?
No. This page compresses existing WebP files. Use the main image compressor for mixed JPEG, PNG, and WebP batches; dedicated conversion pages are planned separately.
When should I use the image file size compressor instead?
Use the image file size compressor when the file must fit a specific KB limit. Use this WebP page when you mainly want quality-based WebP compression.
