A PDF is a page-based document, while a WEBM file is video; converting one is useful when a video player or presentation system accepts WEBM but not PDFs. The conversion renders each PDF page as a still image and shows the pages in sequence for a chosen duration.

What the PDF format is

PDF preserves page layout, text, fonts, and graphics across devices. Office programs, publishing software, and scanners commonly create PDFs, which are used for forms, manuals, reports, and documents intended for consistent printing or viewing.

What the WEBM format is

WEBM is a container for web video, commonly using VP8 or VP9 video codecs and optionally Vorbis or Opus audio. It is suited to browser playback and video platforms. A PDF converted to WEBM becomes a video of page images; it does not retain selectable text, links, forms, or document navigation.

Start the conversion, then download the WEBM file.

Offline with desktop software

Use Poppler’s pdftoppm to render pages and FFmpeg to encode them as video. Both tools are available for Linux, macOS, and Windows. In a terminal, run these commands from the folder containing the PDF:

Render the pages to PNG files: pdftoppm -png -r 150 input.pdf page. This creates files such as page-1.png.
Make a WEBM with each page displayed for three seconds: ffmpeg -framerate 1/3 -i page-%d.png -vf "scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2,format=yuv420p" -c:v libvpx-vp9 -crf 32 -b:v 0 output.webm.

Quality and limitations

The example encodes silent video at 1280 × 720; the scale-and-pad filter fits pages of different proportions on a consistent canvas. Increase the pdftoppm resolution or adjust the FFmpeg canvas dimensions for more detail, bearing in mind that larger dimensions and higher quality can increase file size. The page duration sets the video length: a 20-page PDF at three seconds per page runs for about one minute.
