How to convert WebP to PNG
- Choose one valid static WebP within the 25 MiB and 40 megapixel limits.
- Press Convert to PNG. PicRecast checks the RIFF container for animation, decodes it, and preserves alpha locally.
- Compare both images on the transparency grid, then download the verified PNG.
WebP vs PNG
WebP can use lossy or lossless compression and supports alpha. PNG stores the converted pixels losslessly with broad compatibility, but the output is often larger and cannot restore detail already lost by WebP compression.
WebP transparency is preserved
The conversion canvas remains transparent: fully transparent, semi-transparent, and opaque alpha values pass into the PNG instead of being composited over white or black. The checkerboard preview makes alpha visible.
Animated WebP is rejected
This tool handles still images only. PicRecast checks the VP8X animation flag and ANIM or ANMF chunks before decoding, then returns a clear error instead of silently exporting one frame.
Why the PNG may be larger
WebP is designed for compact web delivery. PNG lossless encoding can use considerably more bytes for the same decoded pixels, so this tool reports the real size change without promising compression.
When PNG is useful
PNG is useful when another application requires PNG, when a lossless editing container is preferred, or when transparent pixels need broad support. Format conversion itself does not improve image quality.
Limitations
This tool processes one static WebP at a time. It does not convert animation, resize, crop, compress, remove backgrounds, or enhance quality. Metadata and color-profile details may not survive browser re-encoding.
Privacy
The selected WebP and generated PNG stay in your browser. There is no conversion API, storage upload, AI request, login requirement, payment flow, or quota call for this tool.
Frequently asked questions
Will WebP transparency remain in the PNG?
Yes. Static WebP alpha is preserved, including fully transparent and semi-transparent pixels, without adding a white or black background.
What happens to an animated WebP?
It is rejected before conversion with an animated-WebP error. The tool never silently chooses only the first frame.
Why is my PNG larger than the WebP?
PNG's lossless encoding is often less compact than WebP, so a larger output is normal.
Are WebP metadata and color profiles preserved?
Not guaranteed. Browser decoding and PNG re-encoding may discard EXIF, ICC, XMP, and other metadata.
Is my WebP uploaded?
No. Container validation, decoding, alpha-preserving drawing, and PNG encoding run locally in your browser.
