Are my images uploaded to a server?

No. The entire conversion runs inside your browser using the HTML5 Canvas API. Your image never leaves your device.

Is transparency preserved when converting WebP to PNG?

Yes. PNG fully supports alpha transparency. If your WebP image has transparent areas, they will be preserved in the output PNG.

Why is the PNG file larger than the original WebP?

WebP uses advanced compression that is generally more efficient than PNG, especially for photographic images. A larger file size is normal when converting to PNG.

Can I convert animated WebP files?

The tool extracts the first frame of an animated WebP as a static PNG. Full animated WebP conversion is not supported in the browser Canvas API.

Is there a file size limit?

The practical limit is your browser's available memory — typically several hundred megabytes. Very large images over 30 megapixels may be slow to process on low-end devices.

Will the PNG quality match the original WebP?

The PNG output is lossless from the decoded pixel data. However, if the original WebP used lossy compression, those artifacts are already baked into the pixels — the PNG preserves them exactly as decoded.
