PNG files — especially screenshots, logos and graphics with transparency — are often several times larger than they need to be. Converting them to WebP keeps the transparency and the crisp edges while cutting the file size dramatically, which is why it has become one of the most common optimisations for modern websites.
PNG's lossless compression is why it's the default for screenshots and logos — and why the files run big. WebP keeps what matters here (full alpha transparency, crisp detail at high quality) while compressing far harder, typically landing 25–35% under an equivalent PNG and often much more for flat graphics. Every modern browser has displayed WebP since around 2020 — our WebP vs PNG guide digs into the numbers.

How PNG and WebP compare
PNG is best for logos, icons, screenshots, graphics with transparency, and images you will edit repeatedly. WebP is best for web images and page-speed optimisation — the best default for most websites today.
Here's how PNG and WebP line up on the things that matter:
| Property | PNG | WebP |
|---|---|---|
| Compression | Lossless | Both (lossy & lossless) |
| Transparency | Yes | Yes |
| Animation | No | Yes |
| Typical file size | Larger than JPG/WebP for photos; efficient for flat graphics | Typically 25–35% smaller than JPG/PNG at equivalent quality |
| Support | Universal — supported everywhere | All modern browsers (Chrome, Firefox, Safari, Edge) since ~2020 |
| Best for | Logos, icons, screenshots, graphics with transparency, and images you will edit repeatedly. | Web images and page-speed optimisation — the best default for most websites today. |
Things to keep in mind when converting PNG to WebP
- For typical images, going from PNG to WebP is straightforward — there are no meaningful downsides to watch for.
PNG to WebP: quality, file size and privacy
You decide the trade-off: the slider sets the WebP compression level, and for typical PNG images anything around 80 looks exactly like the original while shrinking the file substantially.
Nothing you convert is uploaded anywhere. The work happens inside the browser tab, so a sensitive PNG scan gets the same privacy as a meme — and the tool stays free, with no watermark and no account.
Frequently asked questions
Are my files uploaded when I convert PNG to WebP?
No — nothing is uploaded, ever. Your browser does the conversion itself, so your PNG files stay on your device from start to finish.
Is the PNG to WebP converter free?
It's free for personal and commercial use alike. There's no watermark on the WebP output and nothing to sign up for.
Can I convert many PNG files at once?
Yes — drop multiple PNG files and download them individually or as a single zip.
Is WebP supported by all browsers?
Yes. Chrome, Firefox, Edge and Safari (14 and later) all render WebP, so for the vast majority of visitors it simply works — keep a PNG fallback only if you must support ancient browsers.
Does converting to WebP work in every browser?
Creating WebP needs a browser with a built-in WebP encoder — Chrome, Edge and Firefox all have one. Safari can display WebP but can't produce it, so on Safari your PNG files are saved as PNG or JPG instead, with a note explaining the switch.
Will the WebP file be smaller than my PNG?
Usually yes. WebP is typically 25–35% smaller than PNG at the same visual quality, and often more for graphics.
Do I need to install software to convert PNG to WebP?
No installation, no extension, no app. Open this page in your browser — Windows, Mac, Linux or a phone — and convert your PNG files there and then.
Will converting PNG to WebP reduce quality?
You control it. WebP uses adjustable compression; a quality around 80 looks identical to the original PNG for most images while keeping the file small.
