What is WebP
WebP is an image format announced by Google in 2010. Based on the VP8 video codec technology, it achieves significantly smaller file sizes compared to traditional JPEG and PNG. With lossy compression, WebP is 25-35% smaller than JPEG. With lossless compression, it's 26% smaller than PNG. It also supports transparency (alpha channel) and animation.
Compared to JPEG & PNG
JPEG: Ideal for photographs. Achieves high compression ratios, but quality degrades with each re-compression (lossy). Does not support transparency. PNG: Ideal for illustrations and screenshots. Lossless compression preserves quality perfectly, and supports transparency. However, file sizes are larger than JPEG. WebP: Combines JPEG's high compression with PNG's transparency support. 25-35% smaller than JPEG at the same quality, and 26% smaller than PNG with lossless compression.
How to Convert
Simply drag and drop your JPEG or PNG images to convert them to WebP. Adjust quality with the slider and batch download multiple files as a ZIP archive. All processing happens in your browser — images are never uploaded to any server.

FAQ
- What is WebP?
- WebP is an image format developed by Google. It achieves 25-35% smaller file sizes than JPEG and PNG at equivalent quality. It supports both lossy and lossless compression, as well as transparency (alpha channel).
- Which browsers support WebP?
- As of 2026, over 99% of major browsers support WebP, including Chrome, Firefox, Safari, and Edge. Only legacy Internet Explorer cannot display WebP images.
- WebP vs JPEG — which is better?
- WebP is superior in file size (25-35% smaller at the same quality). However, JPEG is safer for print use or maximum compatibility. For web and blog images, WebP is recommended.
