Publisher to FLV Converter

PUB to FLV — Should You Really Convert a Publisher File to Flash Video?

A .pub is a Microsoft Publisher document — a multi-page print layout for flyers, brochures, and newsletters — and FLV is Adobe's Flash Video container from 2003, a format whose player Adobe killed at the end of 2020. These two formats have nothing in common, so this converter does not turn your document into an editable Flash file. It rasterizes each Publisher page to a still image and holds it on screen as a silent FLV clip. For almost everyone the right target is PUB to PDF, which keeps every page, your fonts, and selectable text. Convert to FLV only if a specific, un-migrated Flash pipeline still demands an .flv file.

PUB vs FLV at a Glance

When to Pick FLV (rarely)

• A legacy media server, learning-management system, or video pipeline from the Flash era that still ingests only .flv files.
• A placeholder or static title slide you need to drop into an old Flash/AS3 project that has not been migrated yet.
• An upload form or encoder built around .flv that rejects modern containers — and that you cannot change.
• In short: pick FLV only when something downstream literally demands the extension. There is no quality or compatibility reason to choose it today.

When to Pick PDF or a Modern Video Instead (almost always)

• You want to read, print, email, or archive the layout: use PUB to PDF. PDF keeps all pages, your fonts, and selectable text, and it is exactly what Microsoft recommends before Publisher support ends.
• You just need a shareable image of a page: use PUB to JPG or PUB to PNG.
• You genuinely need a modern video (a flyer looping on a screen, a clip for the web): use PUB to MP4. H.264 in an MP4 plays on essentially every phone, browser, and TV — none of which can play FLV in a browser anymore.

How to Convert PUB to FLV

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. Pick Image Duration: Under "Image Duration" set 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. Set Background Color and Resolution (Optional): Choose a "Background Color" to fill space around the page (default Black), pick a "Video resolution" (keep original or a preset), and leave the "Quality Preset" on "Very High (Recommended)" to keep text crisp. The "Video Codec" defaults to FLV (Sorenson Spark); H.264 is also available under Advanced Options if your target player supports it.
4. Convert and Download: Click "Convert" and download your FLV. No sign-up, no watermark.

Frequently Asked Questions

Does the FLV actually play video, or is it just my page held as a still?

It is a still image held on screen. xconvert rasterizes each Publisher page to a frame and displays it for the Image Duration you set, so a single-page .pub becomes a static, silent clip — a Publisher layout contains nothing to animate. The "video" is simply your page wrapped in a Flash Video container.

Why is my converted FLV silent?

A Publisher document has no audio track, so there is nothing for the converter to carry over. For image-to-video jobs the conversion screen does not expose an audio codec at all, which is why the output is silent by design. To add narration or music, drop the file into a video editor and lay an audio track on top afterward.

What happens to a multi-page Publisher file?

Each page is rasterized to its own frame, so a multi-page .pub plays one page after another like a slideshow, with every page held for the Image Duration you choose. The total length is that duration multiplied by the page count — at the default 5 seconds, a three-page file becomes a 15-second clip. Because a video cannot carry a real page structure, PUB to PDF is the better choice when you want to keep the document as a document.

Will the FLV even play, given Flash is dead?

Adobe ended Flash Player support on December 31, 2020 and began blocking Flash content on January 12, 2021, so no mainstream browser will play an FLV anymore. The container itself still works in desktop players like VLC and anything built on FFmpeg, because they decode the video stream directly without Flash. If you need a file that plays widely today, convert to PUB to MP4 instead.

Should I convert my .pub to FLV or to PDF?

For almost everyone, PDF. Convert to FLV only if a legacy Flash-era pipeline specifically requires an .flv file. If you want to read, email, print, or archive the layout, use PUB to PDF — it keeps your fonts and selectable text across every page, and Microsoft itself recommends moving Publisher files to PDF before support ends on October 1, 2026.

Which video codec does the FLV use, and can I change it?

By default the FLV is encoded with the classic Flash codec — FFmpeg's "FLV" encoder, a Sorenson Spark (H.263) variant — which is what old Flash players and encoders expect. Under Advanced Options you can switch the "Video Codec" to H.264 if your target player supports H.264-in-FLV (Flash Player 9 Update 3 and later did). In our testing, a single-page A4 flyer at the default 5-second duration produced a short, sharp silent FLV with the layout intact; H.264 kept small text cleaner than Sorenson Spark at the same resolution.

Is the conversion private, and are my files kept?

Your file is uploaded over an encrypted connection, converted on our servers, and the result is sent back to you — no sign-up, no watermark, and nothing is shared or made public. Uploaded files and their outputs are deleted automatically a few hours after conversion.
