How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a PNG 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 GIF 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. Open source, every line of conversion code is public.

Formats involved

About PNG and GIF

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.

GIF, Graphics Interchange Format

GIF dates to 1987 and is best known today for animated short clips. The format is limited to 256 colors per frame, which is why photographic GIFs look blotchy, but for low-color animations and reaction loops it's the universal compatibility format. For any animation longer than a few seconds, MP4 is dramatically smaller (often 10-20×) and every social platform converts uploaded GIFs to MP4 internally.

How to open

Every browser and OS displays GIFs inline. Windows, macOS, iOS, Android, and Linux all open them by default with no extra software.

FAQ

Common questions

Is this PNG → GIF converter really free?

Yes. No signup, no watermark, no daily file count limit. The entire engine is open source, you can read the conversion code on GitHub.

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 PNG to GIF?

Screenshots, logos, UI graphics, and any image needing transparency. Short animated loops; reaction images; legacy compatibility. The most common reason to convert is compatibility, GIF works in places where PNG doesn't, or vice versa.

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

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

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.
