WebP to PNG Converter

Convert WebP assets to PNG with transparency preserved — privately in your browser. Processing stays on your device.

How to Use

  1. Drop a WebP file (or click to browse).
  2. Preview appears instantly from a local object URL.
  3. Hit Convert, then Download the PNG — nothing is uploaded.

Key Features & Privacy Advantage

  • All processing happens locally in your browser. Your files are never uploaded to a server.
  • Transparency is preserved via canvas PNG export.
  • Uses the browser’s native WebP decoder — no heavy WASM required.
  • Clear errors for unsupported or corrupt files.

Technical Breakdown

WebP is efficient for the web, but design tools and some print pipelines still prefer PNG. This converter loads your WebP with the Image / createImageBitmap path, draws it to a canvas at native dimensions, then calls canvas.toBlob with image/png.

Because PNG is lossless for typical 8-bit RGBA data, transparency and sharp edges survive the round trip better than JPEG. The trade-off is larger files — expected when you need an edit-friendly raster.

Everything runs in the main thread of your tab. Large megapixel images allocate a full canvas bitmap; if conversion fails with a memory error, try resizing first with Image Resizer & Compressor.

No server round-trip means your product screenshots and brand assets stay on-device. After conversion you can embed with Image to Base64 or recompress with PNG to WebP.

Frequently Asked Questions

Does transparency survive?

Yes. PNG export keeps the alpha channel from the WebP when the browser can decode it.

Do you upload my images?

No. All processing happens locally in your browser. Your files are never uploaded to a server.

What browsers work?

Any modern browser with WebP decode and canvas PNG support (Chrome, Firefox, Safari, Edge).

Why is the PNG bigger?

PNG is usually less space-efficient than WebP. Use it when you need lossless editing or wider tool support.
