Why Convert PUB to 3GP?
Microsoft Publisher (.pub) files can only be opened with Publisher — a Windows-only application. 3GP is a mobile video format for GSM networks. Converting PUB to 3GP is useful for sharing Publisher flyers or brochures as video on mobile phones, sending Publisher designs via MMS where document formats aren't supported, creating mobile-viewable presentations from Publisher layouts, and distributing Publisher content to recipients without Publisher installed.
PUB to 3GP Settings
| Setting | Default | Options |
|---|---|---|
| Video Codec | H.264 | H.264, H.263, MPEG-4, others |
| Audio Codec | AMR | AMR, AAC, MP3 |
| Merge Strategy | Merge images | Single video or per-page |
| Background Color | Black | Black, White, and 20+ colors |
| Image Duration | Configurable | 1/60s to 10 seconds per frame |
Why is the Trim option not available?
Trim is hidden for image-to-video conversions because there is no existing video timeline to trim. Control the video length by adjusting Image Duration and the number of PUB files you upload.
What resolution should I use for readable text?
For Publisher documents with text, use at least 480p to keep text legible. Lower resolutions (240p, 360p) work for simple graphics but make small text unreadable.
Why is AMR the default audio codec?
AMR is the native audio codec for 3GP — designed for GSM mobile networks. Since PUB files don't contain audio, the 3GP output will be a silent video regardless of the audio codec setting.
How long should each page display?
For documents with text, use 8-10 seconds per page so viewers have time to read. For simple graphics or logos, 3-5 seconds is sufficient.
Should I use 3GP or MP4?
For modern phones, use PUB to MP4. 3GP is only needed for legacy GSM feature phones and MMS with strict file size limits.
Can I convert multi-page PUB files?
Each uploaded PUB file is rendered as a single image (first page). For multi-page Publisher documents, each page becomes a separate frame in the slideshow when using "Merge images" mode.
