WebP File Format: Quality, Compression and Browser Use

What is WebP?

WebP is a modern image format designed for efficient web delivery. It supports both lossy and lossless compression and can represent transparency, making it useful for both photographs and many types of graphics.

Common uses

• Website images where download size matters
• Photographs and thumbnails
• Graphics that need transparency but can use a modern web format

Advantages

• Often smaller than JPG or PNG at comparable visual quality
• Supports transparency
• Works with both lossy and lossless compression
• Strong support in current browsers and image software

Limitations

• Some older or specialized workflows may still require JPG or PNG
• A conversion can change image size or quality depending on the selected settings
• Lossy WebP is not appropriate when every pixel must be preserved

Compatible software

Current major browsers support WebP, and most modern image-editing and processing tools can read or write it.

When should you use it?

Choose WebP for modern web delivery when reducing image transfer size is useful.

Consider another format: Use the format required by the destination system when compatibility with older software or a specialized print workflow is more important.
