MKV to GIF Converter — Free Online, Make Animated GIF

Turn short MKV video clips into animated GIFs free online. In-browser, no upload, no signup. Best for clips under 30 seconds.

How to convert MKV to GIF

Step 01

Drop a video file (MKV / MOV / WebM). The first time, the FFmpeg engine downloads (~30 MB).

Step 02

Pick a start time, duration, frame rate, and width. Smaller width = smaller GIF.

Step 03

Click Convert. Encoding happens entirely in your browser — nothing is uploaded.

When the GIF is ready, click Download.

Turn a short video clip into a looping GIF animation, encoded entirely inside your browser. Like every tool on this site, the mkv to gif converter — free online, make animated gif runs entirely inside your browser. Your files are never uploaded to a server. There are no accounts, no monthly limits, and no watermarks — just an honest tool that does one job well.

Common use cases

Creating reaction GIFs or product demos from screen recordings — small files that auto-play in chat apps and embeds without requiring video controls.

Sharing a brief moment from a longer clip on platforms or messaging tools that handle GIFs better than MKV (or that disable video preview by default).

Producing tutorial snippets where a silent looping animation is more effective than a full video player.

How it works

Drop your MKV or other video file in. FFmpeg compiled to WebAssembly opens the video locally — no upload happens.

Pick start and end times, frame rate, and output size. Lower frame rates and smaller dimensions produce dramatically smaller GIFs at the cost of smoothness.

Click convert. The encoder runs locally and produces a standards-compliant GIF that loops by default in every modern browser, chat app, and email client.

Privacy by design

We built this tool to demonstrate that powerful file utilities do not require sending your data to a remote server. Every byte stays on your device.

Hosting and bandwidth aren't free, so the site is supported by privacy-respecting display advertising. Ads never have access to your files because the ads run in a separate iframe and the files never leave your browser memory in the first place.

You can opt out of personalised advertising at any time via the cookie banner at the bottom of the page. Functional behaviour of the tools does not change based on your consent — it only affects the type of ads displayed.

Frequently asked questions

Is it really free?

Yes. There are no fees, no monthly limits, and no premium tier. The tools are funded by display advertising.

Are my files private?

Completely. Everything runs in your browser. We don't have a server that sees your files.

Will it work on my phone?

Yes. Every tool is responsive and works on iOS Safari and Android Chrome. Some heavy operations (large videos, complex PDFs) may be slow on older devices because the work happens locally rather than on a server.

Do I need an account?

No. Tools work immediately, with no signup or login.

Can I use it for commercial work?

Yes. There are no restrictions on the type of file you process or what you do with the result, beyond not violating the law or our Terms of Service.

Where can I report a bug or request a feature?

The Contact page lists an email address — we read every message and try to respond within a couple of business days.
