WebP is a modern image format developed by Google that provides superior compression with 25-35% smaller file sizes compared to JPEG and PNG at equivalent quality. It supports both lossy and lossless compression, transparency (alpha channel), and animation. This tool converts images to WebP format using the browser's Canvas API, with adjustable quality settings.

Select one or multiple images to convert to WebP
Upload a PNG, JPEG, or GIF image by dragging and dropping or clicking to browse. Adjust the quality slider (1-100) to balance file size and visual quality - lower values produce smaller files with more compression artifacts. The tool shows the original and converted file sizes with a compression ratio. Preview the WebP output before downloading. Batch conversion of multiple files is supported.
WebP conversion is essential for web performance optimization - reducing image payload sizes by 25-35% compared to JPEG and PNG without visible quality loss. It is used by web developers optimizing page load times, DevOps teams setting up image processing pipelines, content creators preparing images for fast-loading websites, e-commerce platforms reducing bandwidth costs, and static site generators with image optimization plugins.
The tool uses the Canvas API's toBlob() method with 'image/webp' MIME type for conversion. The quality parameter (0-1) controls lossy compression - 0.8 (80%) provides a good balance of quality and file size. WebP uses VP8 (lossy) or VP8L (lossless) codecs, developed from the VP8 video codec. WebP supports alpha transparency (unlike JPEG), animation (like GIF but smaller), and both lossy and lossless modes. The conversion happens entirely in the browser using native codec support.
WebP is an image format created by Google that uses advanced compression techniques to deliver smaller files than JPEG and PNG. It supports lossy compression (like JPEG), lossless compression (like PNG), transparency (like PNG), and animation (like GIF).
Yes, as of 2023, WebP is supported by all major browsers: Chrome, Firefox, Safari, Edge, and Opera. It covers over 97% of global browser usage according to caniuse.com.
WebP lossy images are typically 25-34% smaller than equivalent JPEG images. WebP lossless images are 26% smaller than PNGs. Actual savings depend on the image content and quality settings.
For web use, WebP is generally the best choice. Use the <picture> element with a WebP source and a JPEG/PNG fallback for maximum compatibility: <picture><source srcset="image.webp" type="image/webp"><img src="image.jpg"></picture>.
