Why Convert PNG to WEBP?
WEBP is the modern image format built for the web — smaller files, same quality, full browser support.
Superior Compression
WEBP files are 25–35% smaller than PNG without any visible quality loss, which helps websites load faster.
Batch Conversion
Batch convert up to 2 PNG images at once on the free plan, or up to 20 on Pro.
Transparency Preserved
Full alpha channel support — your transparent PNGs stay perfectly transparent in WEBP.
100% Secure
Files are processed on secure servers and automatically deleted within 1 hour.
Universal Browser Support
WEBP is supported by all modern browsers including Chrome, Firefox, Safari, and Edge.
No Quality Loss
Lossless WEBP keeps the image identical to the PNG while reducing file size.

What actually happens when you convert
When WebP saves space, and when it doesn't.
Lossy vs. lossless WebP — which do we use?
WebP supports both modes. We convert PNG using lossless WebP compression by default, since PNG itself is lossless — this keeps every pixel identical while still shrinking the file, rather than introducing quality loss you didn't ask for.
Transparency in WebP
WebP fully supports transparency, just like PNG, so any transparent areas in your source image carry over exactly. This is one of WebP's real advantages over JPG, which can't represent transparency at all.
How much smaller does the file actually get?
Lossless WebP typically produces files 25-35% smaller than the equivalent PNG with identical visual quality — the exact savings depend on the image's content, with detailed photos compressing less than flat-color graphics.
Browser and app support for WebP
All modern browsers — Chrome, Firefox, Safari, and Edge — support WebP natively, and most image editors and CMS platforms accept it too. Older software or some email clients may not display WebP — if compatibility is uncertain, keep the PNG as a fallback.
Animated PNG (APNG) — does it convert?
This tool is built for static PNG images. An animated PNG converts using only its first frame, since WebP's own animation format works differently — a dedicated APNG-to-animated-WebP tool handles that conversion if you need an animated result.
Converting back to PNG later
WebP to PNG conversion is lossless in the reverse direction too, when the WebP was created losslessly in the first place — you'll get the original pixel data back. If the WebP was created with lossy compression, that quality loss can't be recovered by converting back.
Frequently Asked Questions
Quick answers on limits, privacy and results.
What Is WEBP and Why Should You Use It?
WEBP is a modern image format developed by Google, designed specifically for the web. It uses advanced compression algorithms to deliver smaller file sizes than PNG and JPEG while maintaining excellent visual quality.
For website owners, switching from PNG to WEBP can significantly improve page load speed, reduce bandwidth usage, and boost Core Web Vitals scores — all factors that affect SEO rankings.
PNG vs WEBP: Key Differences
PNG is a lossless format ideal for graphics with transparency, while WEBP compresses further. A PNG logo that weighs 150 KB can often be reduced to under 100 KB as WEBP, with no visible quality difference.
When to Use WEBP on Your Website
Use WEBP for all images on your website — product photos, blog images, icons, and logos. Most modern CMS platforms like WordPress, Shopify, and Webflow support WEBP natively. Converting your existing PNG library to WEBP is one of the easiest performance wins available.
