PUB Converter

How to Convert PUB to PDF, an Image, or More

1. Upload Your PUB File: Drag and drop your .pub file or click "Upload". The converter accepts Microsoft Publisher documents; batch is supported, so you can queue several .pub files and download them together.
2. Pick an Output Format and Conversion Quality: Choose the target from the format dropdown — PDF to share or print a fixed layout, or an image (PNG, JPG, WEBP, TIFF, GIF, BMP, and more) for previews and the web. For image output, set Conversion Quality in DPI: 150 DPI for screen, 300 DPI (the default) for print, 600 DPI for archival.
3. Set Background, Resolution, or File Size (Optional): Image Transparency fills the page background (default White), Image resolution keeps the original or scales to a Preset Resolution or custom Width × Height, and Image Compression caps output with a Quality Preset or a Specific file size.
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, never shared or made public.

Why Convert a PUB File?

PUB is the proprietary document format of Microsoft Publisher, the desktop-publishing app in the Office family used to lay out flyers, newsletters, brochures, business cards, and labels. The catch is that almost nothing outside Publisher opens a .pub file cleanly — Word and PowerPoint cannot open it natively, and most recipients have no Publisher at all. Converting is how you turn a Publisher-only file into something the rest of the world can read.

That gap is now urgent. Microsoft will retire Publisher after October 1, 2026 — on that date the app reaches end of support, and Microsoft 365 subscribers will no longer be able to install it or open .pub files in it. Microsoft's own guidance is to convert existing files before then: to PDF for viewing and printing, or to Word for editing. If your .pub files matter, exporting them to a durable format now is the safe move.

The two dominant reasons people convert a PUB file:

• Share or print a fixed layout (PDF). A PDF preserves the page design, fonts (when embedded), and print dimensions, and opens on Windows, macOS, iOS, Android, and every modern browser. This is the closest thing to "save my Publisher design so anyone can see it exactly."
• Drop a page into the web, a slide, or an email (PNG / JPG / WEBP). Rasterizing each page to an image gives you a preview that embeds anywhere — a thumbnail for a listing, a figure in a document, or a graphic for social. For print-grade rasters, TIFF at 300–600 DPI keeps the detail.

One honest caveat: this is a one-way render, not a round trip. Complex Publisher layouts — text boxes, overlapping objects, and especially non-embedded fonts — can shift or substitute, and the output is not editable back into Publisher. For a faithful share-and-print copy, PDF holds the layout best; for editing the content, Microsoft points you to Word.

Frequently Asked Questions

What opens a PUB file if I don't have Microsoft Publisher?

Very little opens .pub natively. Word and PowerPoint cannot, and there is no built-in Windows or macOS viewer for it. The free LibreOffice suite (LibreOffice Draw) can import many Publisher files, and some design apps read them with mixed results. The most reliable path for everyone else is to convert the file to PDF or an image first — then it opens anywhere without Publisher installed.

Is converting PUB to PDF the best choice?

For sharing and printing, yes. A PDF preserves the page layout, dimensions, and embedded fonts, and Microsoft itself recommends converting .pub files to PDF for viewing before Publisher's October 2026 retirement. Pick PDF when the goal is "let anyone open and print this design exactly as I made it." Choose an image (PNG/JPG/WEBP) instead when you only need a flat page preview to embed in a webpage, slide, or email.

Will my Publisher layout and fonts stay exactly the same?

Mostly, with caveats. Simple layouts convert cleanly. Complex Publisher pages — many overlapping objects, custom text boxes, or fonts that aren't embedded — can reflow or substitute fonts during conversion, because the output is a render of the page rather than a live Publisher document. PDF holds the layout most faithfully of the targets here. There is no way to convert back into an editable .pub; for editing, Microsoft suggests exporting to Word.

Why is Microsoft retiring Publisher, and what should I do with my .pub files?

Microsoft is discontinuing Publisher after October 1, 2026, when it reaches end of support alongside Office LTSC 2021; Microsoft 365 subscribers will no longer be able to install it or open .pub files in it after that date. Microsoft's recommendation is to convert your existing Publisher files before then — to PDF for viewing and printing, or to Word for editing. Converting now means your designs stay openable long after the app is gone.

What DPI should I pick when converting PUB to an image?

It depends on where the image goes. Use 150 DPI for on-screen use like web pages and slides, 300 DPI (the default) for general printing, and 600 DPI or higher for archival or fine-detail print where small text must stay sharp. Higher DPI means a larger, sharper file and a slightly longer conversion; lower DPI is fine when the page is only viewed on a screen.

What does the converter produce when a page background is transparent?

In our testing, PUB-to-image conversions fill the page background with solid White by default — the Image Transparency setting controls this, and White keeps printed and on-screen pages looking like the original sheet rather than showing a checkerboard. If you specifically need a transparent background, convert to PNG and set Image Transparency to Unchanged; for PDF and JPG output the background is always rendered as a solid color.

Are my uploaded Publisher files 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 brochure, an internal newsletter, or a client proof.
