About PNG files
PNG files are lossless and often large, which slows down web pages. WebP was built for the web and can store the same image in far fewer bytes, with transparency if needed.
Site owners and developers convert PNG to WebP to make pages load faster. All current major browsers show WebP.
How we convert PNG to WebP
- WebP output
- Lossy at quality 85 with encoding effort 4 of 6. A lossless mode is available as an option.
- Transparency
- Kept, because WebP supports an alpha channel.
- Size
- The original pixel size is kept unless you choose a smaller one.
- Measured
- A 212 KB PNG of 2000 by 1500 pixels became a 33 KB WebP.
Common problems and fixes
Thin lines or small text look soft.
Turn on the lossless option. The file is larger but every pixel stays the same.
An older program cannot open the WebP.
Keep the PNG for that program and use the WebP only on your website.
The WebP is not much smaller.
Lower the quality, or resize the image to the width your page shows.
About PNG to WebP Conversion
PNG's lossless quality and transparency support make it essential for web graphics, but file sizes can be substantial. WebP delivers the same capabilities with dramatically smaller files—typically 30-50% reduction while preserving transparency and visual quality.
Our PNG to WebP converter creates optimized images that maintain PNG's features while loading significantly faster. For websites serving PNG graphics, logos, and UI elements, this conversion is one of the most impactful optimizations available.
Why Convert PNG to WebP?
File size reduction is dramatic. WebP's superior compression achieves 30-50% smaller files than PNG at equivalent quality. For a website loading 20 PNG images, that's substantial bandwidth savings and faster page loads.
Transparency preserves completely. Unlike JPG conversion which loses transparency, WebP supports full alpha channel. Logos, icons, and graphics with transparent backgrounds convert perfectly.
Web performance metrics improve. Google's PageSpeed Insights specifically recommends WebP. Converting PNG assets to WebP directly improves Core Web Vitals scores and search rankings.
