How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a GIF 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 WebP 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 GIF → WebP

What this conversion is actually for

WebP is the modern web image format: 25 to 35 percent smaller than PNG or JPEG at the same quality, with alpha transparency support. This converts GIF images to WebP entirely in your browser using the Canvas API, so the file never leaves your device. Transparency in the source is preserved.

A real example

You have a GIF image and a tool, site, or workflow that needs WebP. Drop the GIF here and download the WebP in one step, no upload.

Troubleshooting

The WebP looks slightly different in an old browser.

WebP is supported in all current browsers; very old versions may not render it. The file itself is a standard lossy WebP at quality 0.9.

About GIF and WebP

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.

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.

FAQ

Common questions

Is this GIF → WebP 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 GIF to WebP?

Short animated loops; reaction images; legacy compatibility. Modern web imagery where smaller files load faster. The most common reason to convert is compatibility, WebP works in places where GIF doesn't, or vice versa.

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

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

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.
