Why compress WebP if it's already efficient?

WebP images can still be over-compressed or created at unnecessarily high quality settings. Compressing to a target quality level reduces file size further, which is useful for meeting specific size limits or optimizing page load times.

Is WebP better than JPEG for compression?

Yes. WebP typically achieves 25–34% smaller file sizes than JPEG at equivalent visual quality. A WebP at 80% quality is roughly comparable to JPEG at 90% quality.

Does WebP support transparency?

Yes. Unlike JPEG, WebP supports alpha channel transparency, similar to PNG but with much better compression.

Is WebP supported in all browsers?

Yes. All modern browsers (Chrome, Firefox, Safari 14+, Edge) support WebP. Legacy IE11 does not, but IE11 usage is now negligible.

What is the difference between lossy and lossless WebP?

Lossless WebP preserves every pixel (like PNG) but achieves smaller files than PNG. Lossy WebP discards some detail for much smaller files (like JPEG but better). Most use cases benefit from lossy WebP.

Can I convert a WebP to JPG after compressing?

Yes. After compressing, use the Format Converter to convert from WebP to JPG if your platform requires JPEG format.

How to use this tool

💡

Upload your WebP file and adjust quality. WebP at 80% quality produces significantly smaller files than JPEG at 80% quality.

How It Works

Step-by-step guide to compress webp online:

1
Upload your WebP file
Open Image Compressor and upload your .webp image file.
2
Set the quality level
Start at 80%. WebP at 80% is typically equivalent in quality to JPEG at 90% but much smaller.
3
Preview the compression
Check the output file size and visual quality. Adjust if needed.
4
Download the compressed WebP
Download the compressed WebP file, ready for use on web or mobile.
