About WebP Image Format
WebP is a modern image format developed by Google that provides superior lossless and lossy compression for web images.
WebP images are typically 25%–35% smaller than comparable JPEG and PNG files at equivalent visual quality.
Transparent PNG files retain their transparency when converted to WebP with significant size reduction.
Your images never leave your computer. Conversion is performed entirely within your browser's HTML5 canvas engine.
Privacy: Your image is processed locally in your browser. OfficeKit does not upload or store the image you select in this tool.
Review Notice: Verify your converted image quality, dimensions, and file size before deploying or sharing it.
WebP Format Specifications & Compatibility
Understand how WebP compression improves website performance and how client-side conversion protects your privacy.
Alpha Channel Transparency
Unlike traditional JPEG, WebP natively supports 8-bit alpha transparency. PNG images converted through OfficeKit preserve transparency without unwanted solid backgrounds.
Universal Browser Support
Modern versions of Google Chrome, Apple Safari, Microsoft Edge, Mozilla Firefox, and mobile operating systems natively decode WebP images with hardware acceleration.
Client-Side Privacy Standard
OfficeKit processes your images entirely using standard HTML5 Canvas APIs inside your web browser. No files or metadata are ever transmitted across the network.
