Convert Your .pub Files to an Editable Format

Microsoft Publisher's .pub format is locked to a single application. Copisto unlocks those files. Convert them to an editable format you can work with from any browser.

The Problem with .pub Files

The .pub file format is entirely proprietary to Microsoft Publisher. Unlike .docx or .xlsx, which can be opened by dozens of applications, .pub files can only be opened by Publisher itself. There is no open standard, no published specification, and no built-in conversion tool in Windows or Microsoft 365.

With Publisher reaching end of life on October 13, 2026, this becomes a pressing issue. If you have newsletters, brochures, flyers, or any other documents saved as .pub files, you risk losing access to editable versions of that work entirely.

You could open them in Publisher and "Save As PDF," but that destroys editability. You get a flat image, not a document you can update next month. Copisto solves this by converting your .pub files into a fully editable format.

How It Works

Step 1

Upload

Drag and drop your .pub files into Copisto. Upload a single file or an entire batch, with no size limits on paid plans.

Step 2

Convert

Copisto's conversion pipeline automatically extracts layouts, text, images, and formatting from your .pub file.

Step 3

Edit

Open the converted document in Copisto's browser-based editor. Adjust text, swap images, update layouts. Everything stays editable.

Step 4

Export

Export your finished document as a high-quality PDF, PNG, or JPEG. Ready for print or digital distribution.

Supported Output Formats

Editable Copisto Format

The primary output. Your document becomes a fully editable Copisto project with live text boxes, images, and layouts you can continue working with.

PDF

High-quality PDF export suitable for professional printing or digital distribution. Preserves fonts, colors, and layout exactly.

PNG

Lossless image export at up to 300 DPI. Ideal for web use, social media, or embedding in other documents.

JPEG

Compressed image export with adjustable quality. Good for email attachments and situations where file size matters.

Conversion Pricing

File conversion is available as part of any paid Copisto plan. The conversion cost is $0.15 per page, applied to your account when the conversion completes.

A 4-page newsletter costs $0.60 to convert. A 20-page brochure costs $3.00. You only pay for pages that successfully convert.

Paid plan subscribers ($10/month or $120 lifetime) get access to the full editing suite after conversion, so you can make changes and export as many times as you need, with no additional per-export charges.

What Gets Preserved

Copisto's conversion pipeline is designed to maintain the highest possible fidelity to your original document. Here's what carries over:

  • Page layouts: dimensions, margins, columns, and multi-page structure
  • Text formatting: fonts, sizes, colors, bold, italic, alignment, and spacing
  • Images: embedded photos, clip art, and background images at their original resolution
  • Shapes and borders: rectangles, lines, and decorative borders
  • Colors: fill colors, line colors, and text colors mapped to their closest equivalents
