Why turn a GIF into a PDF?
PDFs can’t animate, but they’re the right tool when you need to review, annotate or print an animation: a storyboard for client sign-off, a motion study for a class, the steps of a UI flow for a bug report, or a flip-book to print and bind. Contact sheets show many frames at a glance; one frame per page is better for presenting or for flip-books.
Use “Frames to include” to sample long GIFs — every 3rd or 5th frame often captures the motion without hundreds of pages. Transparent areas are filled with the background colour you choose, since PDF images here are opaque.
The reverse: PDF to GIF
To animate a document instead — for example a slide deck preview — use PDF to GIF. To get the frames as separate image files, use the GIF Splitter; for print-industry formats, GIF to TIFF creates a multi-page TIFF.
