WebP to PNG Converter
Use the CaseSwitch WebP to PNG Converter to decode WebP to PNG in your browser so editors and printers that lack WebP still get a usable bitmap — with alpha when the source had it. Nothing is uploaded.

Examples
Transparent marketing WebP
Input
badge.webp (alpha)
Output
badge.png · alpha kept for Photoshop/Figma import
Lossy photo WebP
Input
thumb.webp (lossy)
Output
thumb.png · larger; artifacts remain
UI capture
Input
modal.webp
Output
modal.png · sharp pixels preserved from decode
Size expectation
Input
icon.webp (8 KB)
Output
icon.png · often tens of KB; compare before bulk converting
Legacy editor bridge
Input
Tool rejects .webp
Output
Provide .png from this converter, keep .webp for the web
How to use
- Select a WebP file.
- Convert to PNG (no quality control).
- Download and open in your editor — confirm alpha on a checkerboard if you need it.
What this tool is for
Recover a PNG-friendly file from WebP stickers, UI exports, and graphics. If the WebP was lossy, PNG will not recreate missing detail; it losslessly stores the decoded pixels from that point. File size often jumps versus a compact WebP.
How it works
WebP → canvas → PNG blob. No quality slider (PNG). Transparency is preserved when present in the decoded image. Browser must decode WebP. Canvas export typically strips metadata.
When to use it
Opening a WebP in an older editor, handing files to a print vendor that wants PNG, and keeping transparency for further design work.
When not to use it
Expecting a tiny lossy WebP photo to become a high-detail RAW. Filling the disk with huge lossless screenshots without checking dimensions. Prefer WebP to JPG when you need a small opaque photo for legacy mail.
How it compares to related tools
WebP to JPG for opaque compatibility. PNG to WebP is the shrink direction. JPG to PNG is the JPEG sibling of this wrap.
Common mistakes
Converting a 4K lossless WebP screenshot without checking output megabytes, and assuming PNG “upgrades” a lossy WebP.
Lossless after decode
PNG is lossless relative to what the browser decoded. It cannot invent detail WebP discarded. Think of this as a container change plus possible alpha retention, not a restoration filter.
Local Canvas processing
Conversion never leaves your machine. Use that when stickers or unreleased UI must not hit a random upload site.
Frequently asked questions
Will PNG be lossless compared to the WebP?+
PNG is lossless relative to decoded pixels. If WebP already discarded data, PNG cannot invent it back.
Is the file uploaded?+
No. Conversion is in the browser.
Is transparency kept?+
When the WebP had alpha and the browser decodes it, PNG export can retain it. Spot-check the result.
Why is the PNG huge?+
Lossless PNG of a detailed bitmap is often much larger than lossy WebP. That is expected.
Quality slider?+
Not for PNG output. Use WebP→JPG if you need a lossy size knob.
Animated WebP?+
This canvas path is still-frame oriented. Do not expect animation in the PNG.
Are images uploaded to a server?+
No. Image tools use the Canvas API in your browser. Files stay on your device and object URLs are revoked after use.
