WebP
WebP is an image format from Google based on VP8 for lossy stills, with a lossless mode and alpha.
Common uses
- Website images
- Messenger stickers
- Replacing medium JPEGs
Strengths
- Often smaller than JPEG at similar quality
- Alpha without PNG’s photo cost
Weaknesses
- Older tools still choke
- Animation support is a separate question
- Encoder quality varies by browser
Compatibility. Current Chrome, Edge, Firefox, and Safari can decode WebP. Encoding via canvas depends on the browser.
Size and quality. Typically between JPEG and AVIF for photos. Test the actual file.
How to open it. Modern browsers and editors. Preview in ConvertPass’s image tools.
How to convert it. Image converter, with a capability check for encode.
Security and privacy. May contain EXIF or XMP depending on encoder. Canvas re-encode drops it.
