PDF.to reads each frame of your GIF and re-encodes the sequence as a MP4 video with a real video codec. Animated GIF files become smooth MP4 clips; a single still GIF becomes a short fixed-length MP4.
Why convert a GIF to MP4 instead of leaving it as is?
+
A MP4 video is far smaller than an animated GIF of the same length and plays inline on phones without auto-looping quirks. Converting GIF to MP4 is the standard fix for heavy animations that lag in a feed.
Will the MP4 keep the animation timing of my GIF?
+
Yes. PDF.to reads the per-frame delays in the GIF and reproduces them as the frame rate of the MP4, so the motion runs at the original speed.
Does the MP4 loop like the original GIF?
+
The MP4 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 MP4 if you want the endless-loop behavior a GIF has by default.
How small will the MP4 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 MP4 a tenth of the size with no visible loss.
Does the MP4 have sound?
+
No. A GIF has no audio track, so the resulting MP4 is silent. You can add a soundtrack afterward with our video tools if you need one.
What frame rate does the MP4 use?
+
By default PDF.to preserves the effective frame rate of the GIF. Very high-rate animations are capped at 30 or 60 fps so the MP4 stays smooth and broadly compatible.
Will a transparent GIF keep its transparency in the MP4?
+
Standard MP4 video does not support an alpha channel, so transparent areas of the GIF are flattened onto a solid background. Pick the background color in the options panel before converting.
Can I batch-convert many GIF files to MP4?
+
Yes. Upload several GIF files at once and each is converted to its own MP4; the results are zipped for one download.
Is the GIF to MP4 conversion free?
+
Yes, within the free size limit. PRO raises the limit, allows higher output resolutions, and runs conversions in parallel.
Will the MP4 play on social media and messaging apps?
+
Yes. PDF.to outputs the MP4 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?
+
No. Your GIF and the resulting MP4 are encrypted in transit and deleted automatically a short time after the download completes.
