Convert WebP to PNG instantly – no upload needed
Drop a WebP image into the tool above and download a crisp PNG in seconds. Everything runs in your browser, so your image is never sent to any server and stays completely private.
WebP files are great for the web, but not every app, photo editor, or printer accepts them. Converting to PNG gives you a lossless (no quality loss), universally supported image you can open anywhere.
How to convert WebP to PNG
- Choose your file – click the upload area above or drag and drop your .webp image onto it.
- Preview & convert – the tool reads the file, draws it onto an off-screen canvas, and produces a PNG automatically.
- Download – hit the download button to save your new .png file. Done.
There's nothing to install, no account to create, and the conversion is free.
Worked example: WebP to PNG in practice
Say you downloaded a product photo from a website — it arrives as banner.webp (640 × 480 px, 38 KB). After conversion the output is banner.png (640 × 480 px, ~120 KB). The PNG is larger because it stores every pixel without lossy compression, but the image looks identical and can now open in Photoshop, Windows Photo Viewer, or any app that doesn't speak WebP.
Transparency is preserved. If your WebP has a transparent background (alpha channel), the PNG output keeps it — unlike JPEG, which would fill the transparency with white.
How to do this in Python or Node.js
Need to convert a batch of files programmatically? Here are minimal, runnable snippets:
Python (Pillow)
# pip install Pillow
from PIL import Image
img = Image.open('photo.webp')
img.save('photo.png', 'PNG')
print('Saved photo.png')
Pillow handles WebP files on all platforms. The output is a standard 24-bit (or 32-bit with alpha) PNG.
Node.js (sharp)
// npm install sharp
const sharp = require('sharp');
sharp('photo.webp')
.png()
.toFile('photo.png')
.then(() => console.log('Saved photo.png'))
.catch(console.error);
sharp is a fast Node.js image library backed by libvips. It's the go-to choice for server-side batch conversion.
How it works under the hood
The browser's built-in Canvas API does the heavy lifting. When you drop a WebP file, it's decoded by your browser's native WebP decoder (the same engine that renders WebP images on websites). The decoded pixel data is drawn onto an HTML <canvas> element. Then canvas.toBlob('image/png') encodes those pixels as a PNG and hands you the download. No third-party library, no server round-trip.
For the official PNG specification, see the W3C PNG specification. WebP is documented at Google's WebP developer page.
When to use WebP → PNG (and when not to)
| Situation | Use PNG? | Why |
|---|---|---|
| Opening in Photoshop / GIMP | ✅ Yes | Both apps handle PNG natively; WebP support varies |
| Sending to a printer or print shop | ✅ Yes | PNG is universally accepted; WebP often isn't |
| Uploading to apps that reject WebP | ✅ Yes | PNG works everywhere |
| Publishing on a website for web users | ⚠️ Maybe not | WebP is smaller; stay WebP unless you need PNG for compatibility |
| Need to compress a photo further | ❌ No | Convert to JPEG instead — PNG is lossless and larger for photos |
Rule of thumb: WebP → PNG when you need compatibility; PNG → WebP when you need smaller file size for the web.
Your image never leaves your device
This tool runs entirely in your browser. Your WebP file is decoded and re-encoded locally using the Canvas API — nothing is uploaded to a server, logged, or stored. Close the tab and the image is gone. This matters when you're handling private photos, internal design assets, or anything sensitive.
Drop your WebP file into the tool above and download your PNG — it takes about two seconds.
