Good to know
WebP earns its place by beating PNG on size while keeping the two things people rely on PNG for: lossless quality and alpha transparency. A logo with a transparent background stays transparent, and at the same visual fidelity the file typically lands 25–35% smaller. On a busy page that difference compounds across every asset into a noticeably faster load.
The lossless-versus-lossy choice is the decision to get right. Use lossy at around quality 80 for photographs and screenshots, where the compression is invisible and the savings are largest. Switch to lossless for UI assets, icons and anything with sharp edges or flat color regions, where even a faint artifact would show and the source is small enough that lossless stays reasonable.
Browser support is effectively universal now — every current Chrome, Firefox, Safari and Edge renders WebP — so the old compatibility worry is largely historical. If you ever need to reverse the conversion for a tool that predates WebP, WebP to PNG handles the round trip; for photographs where you are not tied to PNG input, Convert to WebP accepts JPG too.
Frequently asked questions
- How do I convert PNG to WebP?
- Drop the PNG, pick a quality (or toggle Lossless), and download the WebP. Batch conversion is supported.
- Why convert PNG to WebP?
- WebP files are smaller than PNGs at the same visual quality, which means faster page loads and lower bandwidth costs while still supporting transparency.
- Will transparency be preserved?
- Yes. WebP supports alpha transparency, so a transparent PNG becomes a transparent WebP.
- Is WebP supported by all browsers?
- Every modern browser supports WebP — Chrome, Firefox, Safari, Edge. Older browsers (pre-2020) may not.
- How much smaller will the WebP be?
- Typically 25–35% smaller at quality 80. Photos see the biggest savings; line art with few colours sees less.
- Lossless or lossy — which should I pick?
- Use lossy at quality 80 for photos and screenshots — it's much smaller. Use lossless when you can't afford any quality change, like for app assets or icons.
- Can I convert multiple PNGs at once?
- Yes. Drop a batch and download the WebP files individually or as a ZIP.
- Are my PNGs uploaded?
- No. Conversion happens in your browser, so your images stay on your device.
- Is the PNG to WebP converter free?
- Yes, totally free, no signup, no watermark.
- Can I convert PNG to WebP on mobile?
