Free online DOC to WEBM converter

When a recipient, presentation system, or video player accepts WEBM but not Word documents, a DOC can be rendered as a timed video of its pages. The result is a page-by-page slideshow, not an editable document or a recording of document content.

What the DOC format is

DOC is the binary word-processing format used by Microsoft Word versions 97–2003. Microsoft Word, LibreOffice Writer, and other compatible word processors can open or create DOC files; they commonly contain formatted text, tables, and images.

What the WEBM format is

WEBM is a media container for web video, commonly carrying VP8 or VP9 video and optionally Opus or Vorbis audio. It is useful for browser playback and video-sharing workflows. Converting a DOC normally renders each page as a still frame shown for a set duration; the output has no audio unless audio is added separately.

How to convert DOC to WEBM

Online on 101convert.com

1. Upload one or more DOC files and select WEBM as the output format. Several files can be processed in a batch; the page shows the per-file size limit.
2. Set show each page for to choose how long each document page appears.
3. Start the conversion, then download the resulting WEBM file or files.

Offline with desktop software

A DOC is not a video stream, so this workflow first renders it to PDF, then converts the PDF pages to images and assembles them into a WEBM. LibreOffice, Poppler’s pdftoppm, and FFmpeg are free tools available for Linux, macOS, and Windows; command names and shell syntax can vary by installation.

1. Open the DOC in LibreOffice Writer and export it to PDF using File → Export As → Export as PDF. Alternatively, from a terminal, run soffice --headless --convert-to pdf --outdir out report.doc after creating the out folder.
2. Render the PDF pages to PNG images at the desired resolution, for example: pdftoppm -png -r 150 out/report.pdf out/page. This produces files such as out/page-1.png.
3. Use FFmpeg to show each page for five seconds and encode the frames as VP9 video: ffmpeg -framerate 1/5 -i out/page-%d.png -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" -c:v libvpx-vp9 -pix_fmt yuv420p -r 30 out/report.webm. Change 1/5 to another duration, such as 1/8 for eight seconds per page. The FFmpeg build must include the libvpx-vp9 encoder.

Quality and limitations

Check the PDF before rendering: missing fonts or layout changes in the word processor will carry into the video. The -r 150 setting controls page-image resolution; higher values improve detail but increase processing time and output size. The conversion turns each page into a static image, so text is no longer selectable and document links, animations, and editing features do not carry over.
