Convert WebP to PNG While Preserving Full Transparency

WebP is excellent for web delivery, but sometimes you need your image in a more universally supported format — especially for editing, print workflows, or applications that don’t yet recognize WebP. This free converter transforms your WebP files into transparent PNG images that work everywhere, all without uploading anything.

Why PNG Is the Right Destination

  • Transparency preserved — both formats support full alpha channels, so transparent pixels come through intact.
  • Lossless fidelity — PNG captures exactly what the WebP decoder produced, no further quality loss.
  • Universal editor support — every major image editor (Photoshop, GIMP, Affinity, Figma, Sketch) handles PNG natively.
  • Safe for archives — PNG is a stable, well-supported format that will keep opening correctly decades from now.

How This WebP to PNG Tool Works

Your WebP file is decoded using your browser’s native WebP support, re-encoded as lossless PNG, then optionally optimized with oxipng — an open-source PNG compressor that finds the smallest possible lossless encoding. Oxipng never changes pixels; it just stores them more efficiently. The Compression slider controls how hard oxipng searches — higher settings produce smaller files at the cost of processing time.

About File Size

PNG files are typically 2–5x larger than the WebP source because WebP uses more efficient compression. That’s the trade-off for universal compatibility and lossless fidelity. For many use cases — editing, archival, graphics work — the larger file is completely worth it.

100% Browser-Based, 100% Private

All processing happens locally using WebAssembly. Your WebP files never touch a server. The tool works offline after the initial page load. There are no file size limits imposed by upload servers, and your images remain private regardless of their content.

FAQ

Frequently Asked Questions

PNG is a lossless format supported by virtually every image editor, operating system, and application. Converting WebP to PNG is ideal when you need to edit the image further, use it in software that does not accept WebP, or want a universally compatible file for presentations, documents, and print.

Yes. Both WebP and PNG support full alpha transparency, so transparent areas in your WebP file will be preserved perfectly in the converted PNG. This makes PNG an excellent destination format for logos, icons, and graphics that need a transparent background.

Usually yes. WebP uses more efficient compression than PNG, so PNG output is typically 2–5x larger than the WebP source. Use the Compression slider to apply oxipng lossless optimization, which can reduce PNG file size by 10–40% without any quality loss.

Yes — the conversion itself is lossless. If your WebP was originally encoded losslessly (e.g., from a PNG source), the output PNG will be pixel-identical to the original. If the WebP was lossy, the PNG captures the exact pixels of that lossy encoding without any further quality loss.

No. All conversion happens entirely on your device using WebAssembly. Your WebP files are never transmitted, uploaded, stored, or accessed by any server. The tool works offline after the initial page load.
