常见问题

Can I convert JPG, WEBP, GIF, or AVIF to PNG?

Yes. If your browser can decode the source image, this tool can draw it to a canvas and export a PNG file. Animated images are converted from the first rendered frame.

PNG 保持透明度吗？

PNG supports transparency. Transparent WEBP or PNG sources should keep alpha when converted. JPEG sources do not contain transparency, so their background remains opaque.

Will converting to PNG make the file larger?

Often yes. PNG is lossless and can be larger than JPG or WEBP. Use PNG for transparency, sharp UI assets, screenshots, and master files; use WEBP or JPG for smaller web delivery when transparency is not needed.
