Convert WebP to PNG Online — Free
Convert WebP to PNG online — lossless output with transparency preserved. Useful when an app rejects WebP or you need a universally compatible file.
How to convert WebP to PNG
- 1
Add your WebP file
Drop or select a .webp file. Files up to 50MB process locally in your browser — nothing uploaded.
- 2
Run the conversion
The WebP is decoded by the browser and re-exported as PNG with DEFLATE compression. PNG preserves the WebP's alpha channel exactly — transparent pixels stay transparent. No further quality loss is introduced during this step.
- 3
Download your PNG
One click saves the result as a .png file. Your original file stays on your device.
Why convert WebP to PNG?
Some image editors (older Photoshop, Paint, Windows Photo Viewer), older Office versions, certain CMS uploaders, and many enterprise imaging tools only accept PNG. Converting from WebP gives you a universally compatible file at the cost of larger file size.
Common WebP to PNG use cases
- Importing a WebP into Photoshop CS6 or earlier (WebP support was added in Photoshop 23.2 / early 2022 via plugin, native in 24+)
- Uploading to a CMS or asset manager that rejects WebP on upload (older Confluence, Jira, SharePoint, and WordPress pre-5.8)
- Preparing WebP assets for a team still using Windows Photo Viewer or legacy image preview tools
- Archiving a master copy of a design asset delivered as WebP where the archival standard is PNG
What file size to expect
A 1600×900 lossy WebP at quality 80 is typically 80-140 KB. The PNG output lands at 280-600 KB — 2-4× larger. Lossless WebP sources re-encode to PNG at roughly 1.3-1.5× the WebP size (PNG's DEFLATE is less efficient than WebP's lossless scheme).
Technical notes: WebP → PNG
PNG and WebP are both lossless-capable, but they use different compression schemes. PNG uses DEFLATE (zlib), which compresses horizontal pixel runs efficiently but struggles with diagonal patterns and noise. WebP lossless uses predictive coding with a more sophisticated dictionary. When converting from lossy WebP, the PNG captures the WebP's decoded pixels exactly — including any VP8 compression artifacts present in the source. No new artifacts are introduced. Canvas-based conversion drops ICC color profiles and EXIF metadata chunks.
Compatibility and browser support
PNG is universally supported — every modern OS, browser, and image viewer since the late 1990s. WebP input requires a browser that decodes WebP (Chrome, Firefox, Safari 14+, Edge). Very old browsers will fail to load the WebP input.
WebP vs PNG
| WebP | PNG | |
|---|---|---|
| File size | Smallest at equivalent quality | Larger (lossless) |
| Quality | Lossy or lossless | Lossless |
| Transparency | Yes | Yes |
| Browser / app support | Modern browsers (Chrome, Firefox, Safari, Edge) | Universal |
| Best for | Web images, performance-focused sites | Screenshots, logos, graphics with transparency |

Frequently Asked Questions
Will the PNG be larger than the WebP?
Yes — PNG is less efficient than WebP. Expect 2-4× the file size from lossy WebP, or 1.3-1.5× from lossless WebP.
Transparency preserved?
Yes, fully. Both WebP and PNG support an alpha channel, so transparent pixels stay transparent at the same coordinates.
Quality loss during this step?
None — PNG is lossless. The conversion preserves the WebP's decoded pixels exactly, including any compression artifacts that were already in a lossy WebP.
Does it work for animated WebPs?
Only the first frame is extracted — PNG is a static format. For animated WebPs, consider converting to animated GIF or MP4 instead.
Will ICC profiles survive?
No — Canvas-based conversion drops ICC color profiles. Colors are interpreted as sRGB during rendering.
File size cap?
50MB per WebP input. Everything runs in your browser.
