How to use the MKV to GIF converter
- Choose the MKV. Large files are fine; only the part you choose is processed.
- Enter the start time of the scene and its length.
- Choose a width and frame rate.
- Make the GIF and download it.
Working with long files
The converter jumps straight to your start time, so making a 4-second GIF from a 2-hour MKV is fast. Subtitles inside the MKV are not burned into the GIF.
Good to know
Each GIF gets its own optimised 256-colour palette built from your clip, with ordered dithering that keeps gradients smooth without the flicker of error-diffusion dithering. GIFs loop forever by default. The longest clip is 30 seconds.

Frequently asked questions
Can I add the subtitles to the GIF?
Not on this page. GIFs are made from the picture only.
Do I have to pay or sign up to use the MKV to GIF Converter?
No. There is no account, no payment and no watermark. The only limit is 1 GB per file, set by what browsers can handle.
Is my file uploaded to a server?
No. The converter runs inside your browser using WebAssembly, so your file is processed on your own device and never sent to us or anyone else.
Can I use it on my phone?
Yes. Open the page in your phone's browser and choose a file. Phones have less memory than computers, so very large files are better converted on a laptop or desktop.
