does gif to pdf keep the animation

A PDF page is a static document format — it renders one fixed layout of text and images, the same every time it's viewed, with no concept of a timeline or frame sequence. An animated GIF, by contrast, is fundamentally a sequence of frames displayed one after another over time. These two formats are structurally incompatible for preserving motion, regardless of which conversion tool you use.

When this tool converts a GIF to PDF, it captures whichever frame the browser is displaying at the moment the file finishes loading — for an animated GIF, that's almost always the first frame, since the animation hasn't had a chance to advance yet by the time the image is drawn onto canvas. The rest of the animation's frames are simply not part of the output.

If you specifically need to preserve an animated GIF's full sequence in some form, the realistic options are different from a static PDF: converting the GIF to a video file (which does support motion) is the appropriate path, or extracting and printing multiple key frames as separate images if you need paper documentation of specific moments in the sequence — neither of which this tool does, since it's built specifically for GIF-to-PDF, not GIF-to-video or frame extraction.

For a static GIF, none of this applies — there's only one frame, and it converts to PDF exactly as you'd expect, with no missing motion to worry about.
