Why convert to WebP?
Up to 30% smaller files
WebP consistently produces smaller files than JPEG and PNG at equivalent visual quality — improving your Core Web Vitals score.
Fully browser-based
Conversion uses the Canvas API natively in your browser. No files are sent to any server — your images stay private.
JPG · PNG · GIF supported
Convert from JPEG, PNG, and GIF to WebP. Batch-process multiple images at once and download as a ZIP archive.
What is WebP and why does it matter?
WebP is a modern image format developed by Google that provides superior compression for web images. It supports both lossy and lossless compression, transparency (like PNG), and animation (like GIF) — all in a single format that is 25–34% smaller than JPEG.
Google PageSpeed Insights and Lighthouse actively flag JPEG and PNG images and suggest converting to WebP or AVIF. Serving WebP images can directly improve your Core Web Vitals, particularly Largest Contentful Paint (LCP).
Is WebP supported by all browsers?
Yes. WebP has been supported by Chrome, Firefox, Safari (since version 14), Edge, and all modern mobile browsers since 2020. It is safe to use WebP as your primary image format for all web projects today.
