GIF to MKV converter
Turn GIF files into MKV for free. The conversion runs entirely in your browser, so your pictures are never uploaded anywhere.
How to convert GIF to MKV
- Add your GIF files. Drop one or more .gif files on the box above, or tap it to pick them from your device.
- Let it convert. The first image you convert loads the converter once (about 31 MB, then cached). After that it runs on your device; a progress bar shows how far along it is.
- Download the MKV. Press Download next to each file. Nothing was sent to a server, so close the tab and it's gone.
What is a GIF file?
GIF is the classic format for short looping animations and simple graphics. It is limited to 256 colors per frame.
What is MKV?
MKV (Matroska) is a flexible container that can hold any codec, several audio tracks and subtitles. It is popular for downloads and recordings.
Why convert GIF to MKV?
GIF is great for animations that play anywhere without a video player, but only 256 colors, and animated GIFs are very large compared with video. MKV is the better choice for holding many tracks and subtitles in one file; keep in mind phones, TVs, browsers and social networks often won't play MKV.
Will I lose quality?
MKV uses lossy compression tuned so the difference is invisible at normal use. We use high-quality settings by default.
Private by design
Most online converters upload your file to their servers. This one doesn't: the converter itself is loaded into your browser and works offline from there, so your pictures never leave your phone or computer.
