Publisher to MP4 Converter

PUB to MP4 Converter

Microsoft Publisher (.pub) is a print-layout format — a flyer, newsletter, brochure, or poster built in Publisher — while MP4 is the near-universal video container that phones, browsers, TVs, and social platforms all play. Converting .pub to MP4 makes sense in one specific situation: you want to turn a static page layout into a shareable video clip for a website, a digital sign, a social post, or an upload form that accepts video but not documents. This converter renders each Publisher page to a still image and holds it on screen for a set time, producing a silent, motion-free MP4 slideshow of your pages. If your real goal is to read, email, or print the layout, a video is the wrong container — convert to PUB to PDF or PUB to JPG instead.

How PUB to MP4 Conversion Works

There is no motion inside a Publisher document, so the converter builds the video out of stills. Each page is rasterized to an image and encoded as a frame that stays on screen for the "Image Duration" you choose. A single-page .pub becomes a static, silent clip; a multi-page file plays one page after another like a slideshow. Because a page rarely matches the 16:9 shape of a video frame, the converter letterboxes it — padding the empty space with the solid "Background Color" you pick (White by default). Nothing is made transparent: the output is a flat, opaque H.264 video with no audio track, because Publisher files carry no sound to begin with.

How to Convert PUB to MP4

1. Upload Your PUB File: Drag and drop your .pub file onto the page, or click "+ Add Files" to browse. You can queue several Publisher files at once.
2. Set Image Duration: Under "Image Duration," choose how long each page stays on screen — the default is 5 seconds per frame, adjustable from a single frame (1/60s) up to 10 seconds per page.
3. Pick Background Color and Video Resolution (Optional): "Background Color" fills the letterbox padding around each page (default White); "Video resolution" keeps the original size or scales to a preset such as 768p or a fixed 1920x1080. If you upload several files, "Merge images" combines them into one video while "Video per image" outputs one clip per file.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.

Frequently Asked Questions

Does the MP4 actually move, or is it just a still image?

It is a still image held on screen, not animated footage. The converter rasterizes each Publisher page to a frame and displays it for the Image Duration you set, so a single-page .pub produces a static, silent clip. Multiple pages play in sequence like a slideshow, but nothing moves within a page — a Publisher layout contains no motion to animate.

Why is there no sound in my PUB to MP4 video?

Publisher documents have no audio track, so there is nothing for the converter to carry over and the output MP4 is silent. The conversion screen does not show audio-codec options for image-to-video jobs for that reason. If you want narration or background music, add it afterward in any video editor.

How long will the MP4 be?

The length is the per-page Image Duration multiplied by the number of pages. At the default 5 seconds per frame, a three-page .pub becomes a 15-second video. Lower the duration for a shorter clip, or raise it (up to 10 seconds per page) to give viewers more time to read each page.

Should I convert my .pub to MP4, PDF, or JPG?

Convert to MP4 only when you genuinely need a video file — a looping display, a digital sign, or an upload form that rejects documents. If you want to read, email, or print the design, PUB to PDF preserves the layout, dimensions, and selectable text far better, and it is the format Microsoft recommends before Publisher's retirement. For a flat page image to embed in a webpage or email, PUB to JPG is the simpler target.

Which video codec and container does the output MP4 use?

The output is an H.264 (AVC) video stream in an MP4 container, standardized as MPEG-4 Part 14 (ISO/IEC 14496-14). H.264 in MP4 plays natively on Windows, macOS, iOS, Android, and every current desktop browser, so the file works almost everywhere without extra codecs. There is no audio stream, because the source .pub has none.

Will my Publisher layout, fonts, and colors look the same in the video?

Standard layouts convert faithfully because each page is rendered to an image before encoding. Files that rely on rare, non-embedded fonts or advanced Publisher effects can shift or substitute fonts once rasterized. In our testing, a single-page A4 flyer at the default 5-second duration and 1080p produced a 5-second, silent H.264 MP4 with the text and colors still crisp; embedding fonts in the original .pub first reduces any drift.

Why are there white bars around my page, and what does Background Color change?

Those bars are letterbox padding. A Publisher page is rarely the same aspect ratio as a 16:9 video frame, so the converter fills the leftover space with a solid color rather than stretching your layout. The "Background Color" setting controls that fill — it defaults to White, so for most print-style pages the padding blends in already; switch it to a color that matches your page if not. The page itself is never made transparent; MP4 has no transparency channel.

Is my uploaded Publisher file kept private?

Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up and no watermark, and your files are never shared or made public — useful when a .pub is a draft flyer, an internal newsletter, or a client proof.
