How to compress a WebP
- 1. Add your WebP images. Select one image or a complete batch from your device.
- 2. Choose the result. Set the image quality and keep the original dimensions or resize them.
- 3. Compare and download. See the original size, compressed size, and saving before downloading.
Smaller WebP images for faster pages
Reduce WebP files for websites, ecommerce stores, content management systems, and modern apps. Existing transparency is retained, and your original image remains unchanged on your device.
Need a specific file size?
Use a target-size compressor when a form or platform requires an image under a fixed limit. Choose WebP as the output format and Crest Convert will find an appropriate setting automatically.

Frequently Asked Questions
How does WebP compression work?
The quality setting controls how much image detail is used when the WebP is encoded again. Lower settings generally create smaller files. Crest Convert shows the completed size and total saving so you can compare the result with the original.
Which WebP quality setting should I choose?
Start around 80% for a practical balance, then move higher for detailed images or lower when a compact upload matters most. The original WebP remains unchanged on your device.
Is this compressor safe?
Yes. Compression happens entirely in your browser. Your images are never uploaded to Crest Convert or stored on our servers.
Can I compress multiple WebP files at once?
Yes. Add multiple WebP files, apply one quality and size setting, then download each result separately or together as a ZIP archive.
Does WebP compression preserve transparency?
Yes. Transparent and semi-transparent pixels remain transparent in the compressed WebP.
What happens to an animated WebP?
The first displayed frame becomes one compressed static WebP image. The original animated file remains unchanged on your device.
Can I resize a WebP while compressing it?
Yes. Resize from 10% to 100% with the output-size slider. Both dimensions change together, which is useful for websites and applications that do not need the original resolution.
Will the compressed WebP keep its metadata?
The compressed WebP keeps the visible image and transparency but does not copy EXIF details such as the camera model, date taken, or GPS location. Keep the original when you need that information.
Why did my WebP not become much smaller?
WebP is already an efficient format, so a previously optimized file may have little unused data left to remove. Try a lower quality or smaller dimensions, then compare the original and completed sizes shown by the compressor.
