PNG to WebP
WebP images are typically 25–35% smaller than an equivalent PNG at the same visual quality, which is why most modern websites serve WebP instead of PNG for faster page loads.
WebP keeps PNG's transparency support, so icons and graphics with transparent backgrounds convert without losing that alpha channel, which isn't true of every alternative format.
As a rule of thumb: stick with PNG when you need it for screenshots, logos, graphics with text, and convert to WebP when web pages that need small, fast-loading images is what you actually need instead. Transparency support carries over either way.

Frequently asked
- Is my PNG file uploaded to a server?
- No — the conversion runs entirely in your browser using the Canvas API. Your image never leaves your device.
- What's the maximum file size?
- There's no hard limit, but very large images (over ~50 megapixels) may be slow to process since everything runs on your device rather than a server.
- Can I convert multiple files at once?
- Yes, the converter above accepts multiple files and lets you download them all at once as a zip.
