Merge PUB to PDF

How to Merge PUB to PDF Online

1. Upload Your PUB Files: Drag and drop or click "Add Files" to select one or more Microsoft Publisher (.pub) files — flyers, brochures, newsletters, postcards, business cards. Batch upload is supported, and files process in your browser session.
2. Pick Combine Mode, Paper Size, and Page Layout: Under Combine?, choose "Single PDF" to bind every .pub into one multi-page document, or "Individual PDFs" for a separate PDF per file. Pick Paper size (Original, Letter, A4 (default), A3, Tabloid, Ledger, Legal, Executive, ARCH_A/B, ISO_B4/B5) and Page layout (Portrait default, or Landscape for tabloid newsletters).
3. Set Margin, Placement, Alignment, and Quality (Optional): Choose a Margin (No margin 0", Narrow 0.5" default, Moderate 0.75x1", Normal 1", Large 2x1"). Set Image placement to "Contained" (default — full design visible, may have whitespace) or "Cover" (fills page, edges may crop). Pick Image alignment (Top, Center default, Bottom). Drag Image Quality (%) from 1 to 100 (default 75) and pick Image Transparency (Unchanged or Removed).
4. Convert and Download: Click Convert. Your merged PDF is ready to download — no Microsoft Publisher install, no Windows VM, no watermark, no sign-up.

Why Merge PUB to PDF?

Microsoft Publisher's end-of-support date is October 1, 2026. After that, Microsoft 365 subscribers can no longer install, download, or use Publisher, and existing .pub files become unopenable through the subscription channel (perpetual / Office LTSC 2024 keeps working). Microsoft's own retirement notice recommends exporting Publisher files to PDF or Word before the deadline. PDF is the safe long-term container — every browser, phone, and operating system renders it identically, and embedded fonts and graphics survive the migration.

• Beat the October 2026 deadline — A school's flyers, a non-profit's annual brochures, or a small business's price lists kept in .pub format become inaccessible to Microsoft 365 subscribers after October 1, 2026. Merging the whole archive into PDFs preserves the layouts before the apps go dark.
• Open .pub files without Publisher — Publisher only runs on Windows, and even LibreOffice Draw and Scribus import .pub with imperfect formatting on complex layouts. Converting to PDF lets recipients on macOS, iOS, Android, Linux, and ChromeOS view the exact original layout.
• Combine multi-part newsletters and brochures — Quarterly newsletters split across 4 separate .pub files (one per issue) merge into a single 16-page yearbook PDF, ready to email or post.
• Print-ready output for shops — Pick A3, A4, Letter, Tabloid, or ARCH_B paper, Landscape orientation, and Image placement = Cover to send a single PDF to print shops instead of asking them to install Publisher.
• Archive Publisher work for compliance — Marketing teams, schools, and HOAs that need 7-year document retention can lock down their .pub library as PDF/A-style archives that won't depend on a retiring app.
• Share designs without distribution friction — Email attachments, Google Drive, Slack, and Dropbox all preview PDF inline; .pub files force the recipient to download and find a viewer.

Frequently Asked Questions

What is the difference between Single PDF and Individual PDFs?

"Single PDF" stitches every uploaded .pub file into one multi-page PDF in upload order — ideal for combining a 4-issue newsletter series, a brochure set, or a year's worth of flyers. "Individual PDFs" produces one PDF per .pub file, returned together in a zip. Use Individual PDFs when each file needs to be distributed separately (e.g., one client per design).

Does this still work after Microsoft retires Publisher in October 2026?

Yes. The tool runs server-side using third-party rendering — it does not require a Microsoft Publisher installation on your machine, and it does not depend on Microsoft's online services. Use it as your migration path: upload your .pub archive, merge to PDF, archive the result. We recommend completing the migration before October 1, 2026, while you still have working Publisher copies for sanity-checking the rendered output against the original.

Does the merged PDF preserve Publisher fonts, colors, and layouts?

The tool renders each .pub page as a high-resolution raster image and places it on a PDF page. Visual fidelity — fonts, colors, shapes, gradients, image positions, master pages — is preserved exactly as Publisher renders them. The trade-off: text in the output PDF is not selectable or searchable because each page is an embedded image. If you need selectable text, convert to Word with a separate tool first, then merge those PDFs.

What is the difference between Cover and Contained image placement?

"Contained" (default) scales each Publisher page to fit fully inside the PDF page margins — the entire design is visible, but you may see whitespace around it when your .pub aspect ratio differs from the chosen paper size. "Cover" scales the design to fill the entire PDF page edge-to-edge — the layout reaches every corner, but content past the page boundary is cropped. Pick Contained for archival/print accuracy; pick Cover for full-bleed display.

How do I control output file size?

Drop Image Quality (%) below the default 75 — 50-60% typically halves the size with negligible visual loss for newsletters and flyers, while 30-40% suits screen-only viewing. Set Image Transparency to "Removed" to flatten transparent layers (smaller and more print-shop compatible). For aggressive post-processing, run the result through our Compress PDF tool to drop another 30-60%.

Can I open .pub files on Mac, iPhone, or Android without converting?

No. Microsoft never shipped Publisher for macOS, iOS, or Android. LibreOffice Draw on Mac and Linux can import .pub files but mangles complex layouts (multi-column text, advanced typography, embedded objects). Converting to PDF is the only way to guarantee the original layout displays identically on any platform — and after October 2026, the only Microsoft-recommended path for 365 subscribers is to migrate to PDF or Word.

Why are A3, Tabloid, ARCH_B, and ISO_B4 in the paper size list?

Publisher is commonly used for designs larger than letter/A4 — tabloid newsletters (11x17"), A3 brochures (297x420 mm), architectural ARCH_A/B sheets, and ISO_B4/B5 booklets. The dropdown carries every size Publisher's own layout presets generate, so a tabloid .pub stays tabloid in the merged PDF instead of being awkwardly down-scaled to Letter.

Can I convert .pub files individually instead of merging?

Yes. Use Convert PUB to PDF for one-at-a-time conversion with the same layout controls, or Convert PUB to JPG if you need image previews of each page. If you already have a stack of PDFs (from any source) and just need them merged, use Merge PDF. The .pub → PDF merge tool on this page is the right choice when you start with Publisher files and want one bound output.

Are my Publisher files private?

Yes. Files upload over HTTPS and are processed in an isolated browser session, then deleted from servers automatically — they are never inspected, indexed, or kept for training. There is no account, no email, no watermark on the output PDF.
