GIF to MKV Conversion FAQ
How do I convert a GIF into a MKV video?
+
PDF.to reads each frame of your GIF and re-encodes the sequence as a MKV video with a real video codec. Animated GIF files become smooth MKV clips; a single still GIF becomes a short fixed-length MKV.
Why convert a GIF to MKV instead of leaving it as is?
+
A MKV video is far smaller than an animated GIF of the same length and plays inline on phones without auto-looping quirks. Converting GIF to MKV is the standard fix for heavy animations that lag in a feed.
Does the MKV loop like the original GIF?
+
The MKV contains the same frames once through. Looping is a player setting rather than part of the video, so add a loop attribute when you embed the MKV if you want the endless-loop behavior a GIF has by default.
How small will the MKV be compared with the GIF?
+
Typically a fraction of the size. Video codecs compress motion between frames far better than a GIF can, so a multi-megabyte GIF routinely converts to a MKV a tenth of the size with no visible loss.
Can I batch-convert many GIF files to MKV?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Is the GIF to MKV conversion free?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
Will the MKV play on social media and messaging apps?
+
Yes. PDF.to outputs the MKV with a widely supported codec and a compatible pixel format, so it plays inline where an animated GIF would otherwise be re-encoded or rejected.
Does PDF.to keep my GIF after conversion?
+
Only for a short time. Your uploaded GIF and the resulting MKV are deleted from our servers automatically about 24 hours after the conversion, which leaves time to download the result. Nobody reads the contents, and nothing is shared.
