Why PNG from WebP
Transparency preserved
PNG supports the same alpha channel WebP uses.

Archival fidelity
PNG is a better archive format than WebP for future-proof storage.
よくある質問
Does this preserve transparency?
Yes. PNG supports the same alpha channel WebP uses.
Is the PNG lossless?
PNG encoding is lossless. The source WebP quality is preserved as-is.
Why is the PNG so much larger?
PNG uses deflate; WebP uses a custom encoder. Expect PNG output 3–8× larger.
Are my files uploaded?
No — zero network activity during conversion.
Any batch limit?
No count or size limit since there is no upload.
Animated WebPs?
Canvas decodes only the first frame.
Is metadata preserved?
No. Canvas re-encoding strips EXIF, XMP, and color profiles.
Why convert instead of just renaming?
File extension alone does not change the format. Real re-encoding is required.
