What is WebP image compression?
WebP is a modern image format designed to provide efficient image compression for the web. Depending on the image and encoding settings, WebP can produce smaller files while maintaining useful visual quality.
WebP compression can use different quality levels. Higher quality generally produces larger files, while lower quality can create smaller files with greater visual changes. This is why selecting an appropriate quality level is important when reducing WebP file size.
This WebP compressor automatically searches through quality settings to find a practical result close to your selected target. Because image content varies, some images may not be able to reach a very small target without noticeable quality loss.
Processing takes place inside your browser using the Canvas API. Your original image does not need to be uploaded to a remote server for compression.
