How to Convert WebP to PNG (Keep Transparency)

How to convert WebP to PNG

When a WebP has a transparent background, PNG is the format to convert it to. Both store an alpha channel, so the cut-out survives — which it would not if you converted to JPG and got a white box around your logo.

This guide covers converting WebP to PNG free in your browser, and why the resulting file is usually larger than what you started with.

Convert WebP to PNG in your browser

The alpha channel is carried straight through, and the conversion happens on your own device.

1Open the free WebP to PNG converter.
2Drag in your .webp files, or click to browse for them.
3Each is decoded and re-saved as a lossless PNG, transparency included.
4Download a single PNG, or a ZIP if you converted several.

Why PNG for editing work

PNG is lossless, so you can open it, mark it up and re-save repeatedly without the compression artifacts that accumulate every time a lossy file is re-encoded. That makes it the safer working format for anything still in progress.

It's also the format design tools, presentation software and documentation systems handle most predictably, particularly where transparency is involved.

Expect a bigger file

WebP compresses far more aggressively than PNG, so a lossless PNG of the same image is routinely several times larger. That's the honest trade for keeping every pixel exact. Convert to PNG for editing and archiving; keep the WebP for anything you're actually publishing to the web.

Frequently asked questions

Does this keep transparent backgrounds?

Yes. PNG supports an alpha channel just like WebP, so transparency comes through intact.

Is the result truly lossless?

The PNG is lossless, but it can only preserve what the WebP already holds. Detail the original WebP discarded can't be recovered.

Why is my PNG bigger than the WebP?

PNG stores every pixel exactly while WebP compresses aggressively. Lossless quality costs space.

Are my images uploaded?

No. Everything happens in your browser.
