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 is a lossless format with full alpha transparency, so it never degrades and is the standard for logos, icons, screenshots and any graphic that needs a transparent background.
WebP is a modern web format that supports both lossy and lossless compression, transparency and animation. It produces noticeably smaller files than JPG or PNG at the same visual quality, which is why it is now the go-to format for fast websites.

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 the two formats 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
- For typical images this conversion is straightforward, with no meaningful downsides.
Quality, file size and privacy
WebP uses adjustable compression, so you can balance quality against file size with the quality slider. A setting around 80 is visually indistinguishable from the original for most images while keeping files small.
Every conversion runs on your own device, so you can convert as many PNG files as you like — with no limits, no watermarks and no sign-up, and nothing is ever uploaded.
Frequently asked questions
Are my files uploaded when I convert PNG to WebP?
No. The conversion runs entirely in your browser — your PNG files never leave your device, so it's completely private.
Is the PNG to WebP converter free?
Yes. Converting PNG to WebP is free and unlimited, with no sign-up and no watermark.
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 — every modern browser (Chrome, Firefox, Edge and Safari 14+) and platforms like WordPress and Shopify display WebP. Only very old browsers need a PNG fallback.
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 any software?
No. The PNG to WebP converter runs in your web browser, so there's nothing to download or install — on Windows, Mac, Linux, Android or iPhone.
Will converting reduce the image quality?
You control it. WebP uses adjustable compression; a quality around 80 looks identical to the original for most images while keeping the file small.
