WebP / AVIF Converter
About this Tool
WebP / AVIF Converter is an image conversion tool that runs entirely in your browser. It executes all processing on the client-side (WASM) without uploading images to a server, enabling privacy-safe and high-speed conversions.
Key Features
- WASM-based High-Speed Conversion: Achieves native-level processing speed using WebAssembly
- Privacy Protection: Image data is never sent to the server. All processing is completed within the browser.
- Quality Comparison Feature: Compare image quality before and after conversion with a slider to find the optimal settings.
- SEO Optimization: Option to automatically convert filenames to alphanumeric characters for SEO-friendly filenames.
- Base64 Export: Copy converted images in Base64 format for direct embedding in HTML or CSS.
- Batch Processing: Convert multiple images simultaneously and download them all as a ZIP file.
Supported Formats
- WebP: A high-compression, high-quality image format developed by Google. Can reduce file sizes by 30-50% compared to JPEG and PNG.
- AVIF: The latest image format. Achieves even higher compression ratios than WebP and is gaining attention as a next-generation web standard.
- JPEG: A widely supported format. Ideal when compatibility is a priority.
- PNG: A format that supports transparency. Ideal for logos and icons.
