What it actually does
02
ALPHA
Transparency preserved
Full 8-bit alpha channel survives the round-trip losslessly. Both formats handle transparency natively; Morph never quantizes during conversion.
04
SPEED
Folder of 200, no queue
Free tier has no batch cap. Memory is the only ceiling.
How it works
- Open morph.cool in any modern browser — no account, no install.
- Drag the .webp onto the drop zone, or pick a folder of WebPs.
- Pick PNG from the format menu.
- Morph decodes via Canvas, re-encodes lossless PNG with full alpha.
- Download. The WebP is still where you dropped it from. Nothing uploaded.

Why people need this conversion
Google launched WebP in 2010 and pushed it hard for web delivery — 25–35% smaller than equivalent JPG, full alpha like PNG, animation like GIF. The economics of CDN bandwidth made it inevitable on the publishing side. The compatibility side took a decade to catch up. Safari held out until version 14 in 2020. The big desktop image editor didn't add native WebP until late 2021. Most CMS upload forms still reject it. Email clients flag it as suspicious. Many older Android phones and Windows machines pre-2020 just refuse to render it. So while WebP is great for "browser viewing a hot website", it's hostile for "send a logo to grandma." PNG has been universally readable since 1996 and isn't going anywhere. Convert when you need compatibility; keep WebP when you control the delivery surface.
Where the upload sites still win
If you need batch conversion of a hundred-thousand WebPs every night as part of a CDN pipeline, server-side tools with proper queueing and retry logic still rule. A conversion API is genuinely good for that. Morph is the local-only daily-driver version for everyone trying to get a single file into something Word, Slack, and Outlook will actually display.
Frequently asked
Why do I need to convert WebP to PNG at all?
WebP is Google's modern image format, fantastic for web delivery. But Safari didn't add support until version 14 in 2020, the big desktop image editor only added native WebP in late 2021, many CMS uploaders still reject it, and most macOS apps before Big Sur cannot preview it. PNG is the universal lossless format that has worked everywhere since 1996.
How is this different from the converter sites?
The compressor sites cap free conversions at 5 MB and force an upload to their server. Morph runs the WebP decoder + PNG encoder via Canvas directly in your browser tab — no upload, no queue, no ad wall, no daily quota.
Is the alpha channel preserved?
Yes — full 8-bit alpha channel preserved losslessly. PNG and WebP both support transparency natively, and Morph never compresses or quantizes the alpha during conversion. Animated WebP is decoded as a static first frame.
Will it work on animated WebP?
It will convert the first frame to PNG. PNG itself doesn't support animation in any browser-compatible way — APNG exists but is poorly supported. For animated WebP, use Morph's GIF converter to preserve motion.
Can I batch a whole folder?
Yes. Drop a folder, drop fifty files, drop two hundred. The free tier has no batch limit. The only constraint is your device's available memory.
Does it work on iPhone or iPad?
Yes — Safari on iOS 14+ supports WebP natively and Canvas PNG export fully. Drop a WebP, pick PNG, download to Files. The conversion runs locally on your iPhone, never touches a server.
