PNG vs WebP — What You Need to Know

PNG is the go-to format for images that need transparency or lossless quality — logos, icons, screenshots, and UI elements. The downside is file size: PNG images can be several megabytes, slowing down websites and eating up storage.

WebP solves this problem. Developed by Google, it delivers lossless compression 26% smaller than PNG, with full transparency support. If you choose lossy compression, the savings are even larger — up to 80% — while keeping visual quality virtually identical to the original.

Every modern browser supports WebP, including Chrome, Firefox, Safari, and Edge. If you run a website, switching your PNG assets to WebP is one of the easiest wins for faster page loads and better Core Web Vitals scores.

Frequently Asked Questions

How do I convert PNG to WebP?

Drag and drop your PNG file into the upload area, adjust the quality slider if needed, and click "Convert to WebP". The conversion runs entirely in your browser — no upload, no account, completely free.

Does converting PNG to WebP lose transparency?

No. WebP fully supports alpha channel transparency, just like PNG. When you convert a PNG with a transparent background to WebP, the transparency is preserved exactly as it was in the original file.

How much smaller is WebP compared to PNG?

WebP lossless images are typically 26% smaller than PNG files. With lossy compression at quality 80-85%, WebP files can be up to 60-80% smaller than the equivalent PNG while maintaining visually identical quality. This makes a significant difference for website loading speed.

Should I use lossy or lossless WebP for PNG images?

It depends on your use case. For screenshots, UI elements, and graphics with text, use lossless or high quality (90-100%) to preserve sharp edges. For photographs originally saved as PNG, lossy compression at 80-85% offers the best balance between quality and file size.

Is it safe to convert my PNG files here?

Absolutely. WebPify processes your images entirely in your browser using WebAssembly. Your PNG files are never uploaded to any server — they stay on your device throughout the entire conversion process. No data is collected or stored.
