Complete Guide to Converting Images to WebP
Already have WebP images that are still too large? This free compress WebP tool re-encodes WebP files at a lower quality setting directly in your browser. It helps reduce WebP file size for websites, email, forms, and CMS uploads.
No files are uploaded or stored.
How to Compress WebP Files
- Upload one or more
.webpimages. - Choose a quality level.
- The browser re-encodes the WebP image locally.
- Compare original and compressed sizes.
- Download the optimized WebP file.
If visual detail matters, start with Best or Balanced and reduce quality only as needed.
Best WebP Compression Settings
| Goal | Suggested quality |
|---|---|
| Maximum savings | 60–72% |
| Standard website images | 75–85% |
| Product images | 82–88% |
| High-detail images | 88–92% |
Avoid repeatedly recompressing the same file many times. Keep an original source image when possible.
When to Compress WebP Again
WebP recompression is helpful when:
- A CMS export creates large WebP files
- Product images are still too heavy
- A PageSpeed audit flags large image payloads
- You need smaller images for upload limits
For non-WebP source files, use Compress Image or Image Compressor.

Frequently Asked Questions
Common questions about WebP conversion and privacy.
Can WebP files be compressed again?
Yes. WebP images can be re-encoded at a lower quality setting to reduce file size further. Avoid repeated recompression if you need maximum visual quality.
What quality setting should I use?
For most web use, a quality setting of 75–85 provides an excellent balance between file size and visual quality. Lower values reduce file size further; higher values preserve more detail.
Are my images uploaded to a server?
No. All conversions happen entirely in your browser using the Canvas API. Your images never leave your device, making this tool fully private and secure.
Is there a file size limit?
There is no server-side limit because files are processed locally. Very large images may be limited by your device memory and browser capabilities.
How does WebP improve SEO?
Smaller images load faster, which improves Core Web Vitals metrics like Largest Contentful Paint (LCP). Google uses page speed as a ranking factor, so optimized images can help your SEO.
Can I convert multiple images at once?
Yes. Drag and drop multiple files or select them using the file picker. Each file is converted individually and you can download them one by one or use Download All.
