Upload a PNG file and this tool converts it straight to WebP — entirely in your browser. Nothing is ever uploaded to a server.
Converting PNG to WebP
PNG and WebP serve different purposes, and switching between them is one of the most common image tasks there is — whether it's an iPhone photo saved as HEIC that a website won't accept, or a PNG that needs to shrink down for the web. This tool reads your PNG file into memory, decodes it using the browser's native image renderer, and re-encodes it as WebP — all on your device. Because nothing is sent to a server, it works even on private or sensitive images, and it keeps working offline once the page has loaded. Need a different pair? The full converter below supports HEIC, JPG, PNG, WebP, AVIF, BMP, GIF, TIFF, SVG and PDF in any direction.
How to Use It
- Drag and drop your PNG file into the upload area (or click to browse).
- The output format is already set to WebP — change it if you need a different format instead.
- Adjust the quality slider to balance file size and visual clarity.
- Click Convert and download the WebP result.
- Converting several files? Switch to bulk mode and download everything as a ZIP.
