PNG to WebP Converter — Free & Instant

Q: Is it safe to convert my PNGs here?

Yes. Conversion happens entirely inside the browser using the Canvas API — files are never uploaded to a server, so they stay fully private.

Q: Is there a file size or file count limit?

There's no fixed limit — any number of PNG files can be converted in one batch. Very large batches simply take a bit longer since everything runs on the user's own device.

Q: Can I convert multiple PNGs at once?

Yes, batch conversion is supported — several PNG files can be selected or dragged in together, converted in one click, then downloaded all at once.

Convert PNG images to WebP and reduce file size by up to 50%. Lossless or lossy options available. 100% browser-based — your files never leave your device.

Why Convert PNG to WebP?

PNG files are lossless and support transparency, but they are often very large in file size. WebP provides the same transparency support with up to 50% smaller file sizes, making it ideal for web use. Google recommends WebP for web images to improve page load speed and Core Web Vitals scores.
