WebP to PNG Converter

Quick answer

Convert a WebP back to PNG when something in your workflow, such as an older editing tool, a print shop, or an upload form, simply refuses to open the newer format. The conversion is lossless in both directions when the source WebP was itself lossless.

What the webp to png converter does

WebP is over a decade old now, but plenty of software still does not read it: some print shops still want PNG or TIFF specifically, some older versions of design tools reject WebP outright, and some corporate upload portals only recognise a short, old list of extensions. This tool exists for exactly that mismatch, not because WebP is worse, but because acceptance is not universal.

If the WebP you are converting was saved in lossless mode, this round trip is exact: every pixel comes back out the other side unchanged, and the PNG will typically be somewhat larger than the WebP, mirroring the same efficiency gap in reverse. If the WebP was saved as lossy, converting to PNG locks in whatever compression artefacts that lossy encode introduced; PNG stores them faithfully but cannot remove them.

Alpha transparency carries through completely in either case, since both formats support a full alpha channel. There is no flattening step here, unlike converting to JPEG.

How to use it

  1. Upload the WebP

    Drag or browse. Both lossless and lossy WebP sources are accepted.

  2. Confirm the output

    PNG has no settings to configure; the encoder always produces a lossless file.

  3. Download the PNG

    Use it anywhere WebP is rejected: legacy design software, print submission portals, older upload forms.

Your images never leave your device

The decode and re-encode both happen locally through your browser canvas, which is worth knowing if the file in question is a scanned contract page a colleague saved as WebP from a screenshot tool, and now needs to paste into a document system that still, for whatever internal reason, only accepts PNG.

  • No file is ever uploaded to a server
  • Works offline after the first visit
  • No account, no watermark, no limits

Format and quality tips

Check whether the WebP was lossless first

If you saved it yourself and chose lossless mode, this conversion is exact. If you downloaded it from somewhere and do not know, treat the PNG as carrying whatever compression the original WebP already had.

PNG will usually be larger, and that is expected

PNG cannot match WebP efficiency for photographic content, so seeing the file size grow after this conversion is normal, not a sign anything went wrong.

Frequently asked questions

Why would I convert WebP back to PNG?

Usually because something in your workflow does not accept WebP: an older design tool, a print shop upload form, or a corporate portal with a short list of allowed extensions.

Does WebP to PNG conversion lose quality?

Only if the source WebP was saved as lossy. Converting a lossless WebP to PNG is an exact, pixel-for-pixel copy with no further loss.

Will the PNG be bigger than the WebP?

Almost always, since PNG is generally less efficient than WebP for the same visual content. This is expected and not a sign of a failed conversion.

Does converting WebP to PNG keep transparency?

Yes, both formats support a full alpha channel, so transparent and semi-transparent pixels carry over exactly.

Can old software actually not open WebP files?

Yes, plenty of design and print software predates widespread WebP support, and some corporate upload systems still only whitelist a short, older list of formats.

Is there any downside to always converting WebP to PNG for safety?

Only file size. PNG is the safer choice for compatibility but is typically larger, so it is worth keeping the WebP as your working copy and only converting when a specific tool demands it.
