Convert your images to WebP format with our free online WebP converter. Achieve superior compression and faster loading times for modern web applications.

What is WebP?

WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster. WebP lossless images are 26% smaller in size compared to PNGs, and WebP lossy images are 25-50% smaller than comparable JPEG images.

WebP Format Features

Superior Compression: 25-50% smaller file sizes compared to JPEG/PNG
Transparency Support: Full alpha channel transparency like PNG
Animation Support: Can create animated images like GIF but with better compression
Both Lossy and Lossless: Choose compression type based on your needs
Wide Color Support: Supports all color profiles and bit depths
Metadata Support: Can store EXIF, XMP, and ICC color profiles
Fast Decoding: Optimized for quick display in browsers

When to Use WebP

Best For:

Web applications and websites
Progressive web apps (PWAs)
E-commerce product images
Blog and content images
Social media platforms
Mobile applications
Images requiring transparency
Animated graphics (instead of GIF)

Consider Carefully:

Older browser support requirements
Email newsletters (limited support)
Print materials
Legacy systems integration
Third-party services without WebP support

WebP Compression Modes

Lossy WebP

Uses predictive coding to encode an image, similar to VP8 video codec. Ideal for photographs and complex images.

25-50% smaller than JPEG
Adjustable quality settings
Better for photographs

Lossless WebP

Uses advanced techniques like local palettes and image transformations to achieve better compression than PNG.

26% smaller than PNG
No quality loss
Better for graphics and logos

Start with 80% quality for lossy WebP to balance size and quality
Use lossless WebP for images requiring perfect quality
Test WebP images across different browsers and devices
Monitor Core Web Vitals improvements after implementing WebP
Consider server-side detection to serve WebP to supporting browsers
Use Content Delivery Networks (CDNs) that automatically serve WebP
