Publisher to HEVC Converter

Publisher to HEVC Converter

This converter turns a Microsoft Publisher document into an H.265/HEVC-encoded slideshow: every page of the .pub is rendered to an image, and those images become the frames of a single video file. HEVC is the successor to H.264, standardised in 2013 as ITU-T H.265 and ISO/IEC 23008-2, and it typically reaches similar quality at meaningfully lower bitrates — which is why it is the right target when file size matters more than universal playback. Before you use the result, read the section below on what a .hevc file actually is, because the extension is misleading in a way that trips up most media players.

What a .hevc File From This Converter Really Is

"HEVC" names a codec, not a container, so an .hevc extension does not describe a file format on its own. Our pipeline does not write a raw elementary stream under that name — it writes a Matroska file and gives it the .hevc extension you asked for.

How to Convert Publisher to HEVC

1. Upload Your Publisher File: Drag and drop your .pub onto the page or click "+ Add Files" to browse. Several Publisher files can be queued together.
2. Confirm the Video Codec: "Video Codec" offers H.265 and HEVC, which select the same encoder under two names. There is no wrong choice here.
3. Set Image Duration and Quality (Optional): "Image Duration" controls how long each page holds on screen, from a fraction of a second to 10 seconds. "Quality Preset" starts at "Very High (Recommended)"; "Video resolution" offers Keep original or Fixed Resolutions presets.
4. Convert and Download: Click "Convert", download the file, and rename it to .mkv if your player refuses to open it. Files upload over an encrypted connection and are deleted automatically after a few hours. No sign-up, no watermark.

HEVC Compared With the Other Video Targets

Frequently Asked Questions

Why will my media player not open the .hevc file?

Because the extension does not match what most players expect. Many players treat .hevc as a raw elementary stream and refuse a file that is actually a Matroska container. The file itself is fine — rename it from .hevc to .mkv and it should open immediately in VLC, MPV, or anything else that reads Matroska. Nothing about the video data changes when you rename it; you are only correcting the label. If you would rather not rename anything, convert to Publisher to MKV instead and get the same content with the right extension from the start.

Does the output carry an audio track?

No. General HEVC conversions on this site carry an AAC audio track, but that only applies when the source has sound. A Publisher document has no audio at all, so the pipeline encodes a video-only file and the audio controls do not render. There is no setting that will add silence-as-a-track or restore audio. If you need music or narration over the slideshow, add it in a video editor afterwards.

How long will the finished video be?

Pages multiplied by seconds per page. At the 5-second default a six-page brochure produces a 30-second video. "Image Duration" adjusts this from a fraction of a second up to 10 seconds per page, applied uniformly — there is no way to give individual pages different durations in one pass.

Is HEVC actually smaller than H.264 for a page slideshow?

Usually yes, though the gap is narrower than it is for real footage. HEVC's advantage comes largely from better prediction of motion and complex detail, and a slideshow of static pages has neither — most frames are exact duplicates, which any modern codec compresses to almost nothing. You will still generally see a smaller file than the equivalent H.264 encode, but if maximum compatibility matters more than a modest size saving, Publisher to MP4 is the more sensible target.

Why is the frame rate only 1 fps?

Because there is no motion to capture. A page held on screen for five seconds is five identical frames at 1 fps, and encoding at a higher rate would only duplicate more identical frames for no visual gain. B-frames are also disabled for still content, since they add a start-up delay without helping compress frames that are already identical.

What does the Background Color option change?

Only the padding bars around the page, not the page itself. In our testing, LibreOffice's Draw-based PDF export paints an opaque white page background, so each page reaches the encoder already flattened with nothing transparent left to fill. The colour becomes visible when you pick a frame shape that differs from the page shape — a portrait A4 page placed into a 1920 × 1080 frame leaves bars on both sides, and those bars take the chosen colour.

Can I set a target bitrate or file size?

Not on this path. Because a still image has no source bitrate to scale from, the bitrate and target-file-size modes are hidden and only Quality Preset, Constant Quality and Constraint Quality are offered. Start with Quality Preset, which opens at "Very High (Recommended)". Constraint Quality is the option to use if you need to cap the maximum bitrate. Reducing the resolution remains the most predictable way to shrink the file.

Will the text on my pages remain searchable in the video?

No. Every page is rasterized into a frame, so the text becomes pixels and cannot be searched, selected or copied. If preserving the actual words matters, convert to Publisher to PDF, which keeps text as text, and treat the video as a presentation artefact rather than a document.

How is my Publisher file handled, and is it kept private?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared or made public. For long publications the practical limit is upload time rather than the number of pages.
