Turn your MKV file into a GIF that plays where you need it, right in your browser.
Drag and drop the file, or click to browse. Files up to 500 MB are supported, and nothing is installed.
GIF is already selected, so there is nothing to configure. You can switch formats in the panel if you need to.
We convert on our servers, usually in under a minute. Create a free account to download the GIF, or keep editing the file in REQO.
MKV (Matroska) is an open container that can hold any codec plus unlimited audio tracks, subtitle tracks and chapters. That flexibility makes it great for archives and useless for sharing.
The practical problem: Browsers, phones and social uploads reject MKV almost universally. Editing tools often refuse to import it, or import picture without audio. Nobody can preview it without installing VLC first.
GIF solves that. Auto-plays and loops in email, docs, issue trackers and chat apps where video is blocked. Needs no player, no controls and no click to start.
| MKV | GIF | |
|---|---|---|
| Container | Matroska | Graphics Interchange Format |
| Typical codecs | Almost anything: H.264, HEVC, AV1, VP9 | Indexed colour, up to 256 colours, no audio |
| Best for | Archiving with multiple audio and subtitle tracks | Short silent loops in docs, chat and email |
| Plays on | VLC and desktop players; rarely anywhere else | Everywhere an image can be shown |
| File size | Depends entirely on the codec inside | Huge for anything over a few seconds |
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the GIF itself beyond the free-plan badge.
No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android.
Visibly, yes. GIF is limited to 256 colours, so gradients and camera footage band. It is the right format for short UI loops and reaction clips, not for anything you want to look sharp.
Up to 500 MB per file. For anything bigger, trim or compress it first, both are free tools here.
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
