Compress WebP Images Online
WebP is Google's modern image format designed specifically for the web — offering superior compression compared to both PNG and JPG. Even WebP images can sometimes be larger than necessary, especially when exported from design tools. Our WebP compressor helps you squeeze out every last kilobyte.

Why Use WebP?
WebP images are typically 25–35% smaller than equivalent JPG images and 26% smaller than PNG, at the same visual quality. All major modern browsers support WebP. Using WebP on your website can dramatically improve page load speed, Core Web Vitals scores, and user experience — while saving bandwidth.
Lossy vs Lossless WebP
WebP supports two compression modes. Lossy WebP uses prediction coding and achieves very high compression ratios, ideal for photographs. Lossless WebP achieves file size reductions of 26% compared to PNG on average while preserving every pixel exactly — ideal for logos, icons, and graphics with transparency.
Supported Formats
This tool accepts WEBP files up to 20 MB per file. Process up to 20 images per batch.
Frequently Asked Questions
-
Yes. WebP is supported by all major modern browsers including Chrome, Firefox, Safari (since version 14), Edge, and Opera. It has over 97% global browser support as of 2024.
-
Yes! WebP supports transparency (alpha channel) in both lossy and lossless modes. This makes it a great replacement for PNG in many use cases.
-
Both are modern web image formats. AVIF generally achieves better compression than WebP, especially at lower quality levels, but has less browser support. WebP is the safer choice for broad compatibility today.
