How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a WebP from your desktop. Files of any size, there's no upload, so there's no upload limit.

  2. 2

    Convert in your browser

    The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.

  3. 3

    Download

    Get your PNG the moment the conversion finishes. Convert another, or close the tab.

Files stay on your device

Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.

No file size limit

Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.

Free, no signup, no ads on conversions

No account required. No watermark on the output. No queue. Drop a file, get a converted file.

Why convert WebP → PNG

What this conversion is actually for

You downloaded a WebP (Google Images, a website's right-click-save, a generated AI image) and a tool you need to use won't accept it, older Photoshop, a print shop's upload form, a legacy CMS. PNG is the universal lossless fallback that everything from 1996 onward reads, and it preserves the WebP's transparency.

A real example

You saved an illustration from a website and it came down as `art.webp`. Your print-on-demand service only accepts PNG/TIFF. Convert here, upload the PNG, transparency preserved, no quality loss.

Troubleshooting

The original WebP was animated and only the first frame converted.

Animated WebP → PNG only extracts the first frame (PNG isn't an animation format). If you need the full animation, convert WebP → GIF instead, or WebP → MP4 for better quality.

About WebP and PNG

WebP, Web Picture

WebP is Google's image format, designed in 2010 specifically for the web. It compresses 25-35% smaller than JPG at equivalent quality, supports transparency like PNG, and supports animation like GIF. Browser support is universal as of 2020 (Safari was the last holdout). The main reason most images aren't already WebP: legacy software (older Office versions, some email clients) doesn't open it.

How to open

All modern browsers display WebP natively. Photoshop added native support in version 23 (2021); earlier versions need a plugin. macOS Preview reads WebP since macOS Monterey. On Windows, the Photos app supports it; older viewers may not.

PNG, Portable Network Graphics

PNG is a lossless image format, the file size is larger than JPG, but every pixel is preserved exactly. It supports full transparency (alpha channel), which JPG cannot. Created in 1996 specifically as a patent-free replacement for GIF, PNG is the standard for screenshots, logos, icons, UI graphics, and any image that needs sharp text or transparent backgrounds.

How to open

Universal support, every OS, browser, and image editor reads PNG. macOS Preview, Windows Photos, and any web browser open PNGs without any conversion step.

FAQ

Common questions

Is this WebP → PNG converter really free?

Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.

Where does my file go when I convert it?

Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.

What's the maximum file size?

Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.

Why convert WebP to PNG?

Modern web imagery where smaller files load faster. Screenshots, logos, UI graphics, and any image needing transparency. The most common reason to convert is compatibility, PNG works in places where WebP doesn't, or vice versa.

How do I open a WebP file in the first place?

All modern browsers display WebP natively. Photoshop added native support in version 23 (2021); earlier versions need a plugin. macOS Preview reads WebP since macOS Monterey. On Windows, the Photos app supports it; older viewers may not.

Does this work offline?

Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.

Can I convert multiple files at once?

Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
