Convert PNG to WebP when you need modern web assets with smaller file sizes. Upload PNG images and download WebP files for faster page loads while preserving transparency when supported.
WebP often cuts PNG size dramatically on photographic and gradient content.
Keep PNG masters for print and tools that do not render WebP.

How it works
Upload a JPG, PNG, or WebP image, choose an output format, and optionally set quality for JPG or WebP. Conversion runs in your browser with the Canvas API—files are not uploaded to a server. Converting to JPG fills transparent areas with white.
Limitations
Format conversion may drop animation, ICC profiles, or EXIF metadata depending on the target format.
Privacy and file handling
Your data is processed in your browser and is not uploaded to our server.
