PNG to WebP

Compress PNG to modern WebP format online free. Reduce PNG file size while preserving transparency with WebP.

Convert PNG images to WebP while keeping transparency intact — and typically at a fraction of the file size. This browser-based tool re-encodes your PNGs locally, preserving alpha channels for logos, UI assets, and product cutouts while trimming the weight that slows pages down on mobile connections.

Transparency Without the Weight

WebP supports full alpha transparency just like PNG, but its compression is smarter about the data around those transparent edges. The result: logos and cutouts that look identical against any background yet load noticeably faster. For asset-heavy interfaces, the savings compound with every icon and illustration on the page.

Quality Settings Explained

A balanced quality level preserves the crisp edges that define PNG-sourced graphics while still capturing WebP's size advantages. Push the slider higher for intricate illustrations with fine linework; dial it back for simple marks that hold up under aggressive compression.

  • Quality 85-90: detailed illustrations and product art
  • Quality 75-82: solid default for UI and logo assets
  • Quality 65-72: dense grids of thumbnails or icons

Lossless Mode for Critical Artwork

When absolute pixel identity matters — brand marks, pixel art, assets feeding a further edit — lean on lossless WebP output. It behaves like PNG in fidelity while still exploiting WebP's packing efficiency, often landing smaller than the PNG you converted from.

Browser Support Reality

Every current browser renders WebP, and mainstream CMS platforms accept it on upload. For audiences stuck on very old software, pair WebP with a PNG fallback in responsive markup. In most consumer-facing projects today, shipping WebP alone is entirely reasonable.

Migration Tips

Convert a representative sample of your PNG library first, compare sizes and visual quality at real display sizes, then roll through the rest. Local processing means client assets and pre-launch branding remain on your device for the entire migration.
