What is PUB?

Microsoft Publisher (PUB) is a desktop publishing format used for creating professional layouts, newsletters, flyers, and marketing materials.

What is CFG?

Configuration (CFG) files store application settings and parameters in plain text, often using INI-style key-value pairs.

When Should You Use PUB vs CFG?

Use PUB When...

Reach for PUB when your priority is desktop publishing, flyers, newsletters — its efficient compression makes sharing fast and storage minimal.

Use CFG When...

Reach for CFG when your priority is application config, ini-style settings — its uncompromising quality ensures every detail is preserved.

PUB vs CFG: Key Differences

  • •The core technical difference: PUB relies on lossy compression whereas CFG uses lossless compression.
  • •Moving from PUB (lossless) to CFG (lossless) means the output file will be larger — but every bit of the original is preserved.
  • •How transparency is handled: CFG supports transparency, so alpha information is preserved during conversion.
  • •Storage footprint: 500KB to 50MB with images for PUB vs Very small, text only for CFG.
  • •Use case fit: PUB targets desktop publishing, flyers, newsletters and CFG targets application config, ini-style settings — your choice depends on which workflow stage you are serving.

Advantages of PUB

  • ✓PUB uses lossy compression tailored for Desktop publishing, flyers, newsletters.
  • ✓PUB is supported natively on virtually every device, browser, and operating system.
  • ✓PUB files are compact and quick to transfer, even over slow connections.
  • ✓PUB integrates seamlessly with all major creative tools and workflows.

Advantages of CFG

  • ✓At its core, CFG relies on lossless encoding — a design choice that makes it perfect for Application config, INI-style settings.
  • ✓You won't run into compatibility issues with CFG — it's a universal standard across platforms.
  • ✓File size management with CFG: larger files guaranteed to match the original exactly.
  • ✓Every major application in the Application config, INI-style settings space supports CFG natively.

Best Practices for PUB to CFG Conversion

  • →Before converting PUB to CFG, review the document structure — multi-column layouts, text boxes, and floating images behave differently across formats
  • →Export a PDF preview alongside the CFG file so you have a reference of how the document should look
  • →Check that hyperlinks and cross-references survived the PUB to CFG conversion — some formats handle links differently
  • →Run a spell check before conversion to avoid propagating errors into the final document
  • →Keep the original editable file in case the conversion introduces layout shifts
  • →Test the output on at least two different applications or devices

Troubleshooting PUB to CFG Conversion

  • !PUB to CFG formatting looks off → complex layouts with tables and columns may shift between formats
  • !Fonts render differently in CFG → embed fonts or use standard web-safe fonts before converting
  • !Images missing from the CFG output → ensure images are embedded in PUB, not linked externally
  • !Tracked changes disappeared after converting PUB to CFG → some document formats don't support revision tracking

Does converting PUB to CFG lose quality?

No, converting PUB to CFG does not cause additional quality loss — CFG uses lossless compression. However, any artifacts already present in the original PUB file will persist in the CFG output.

What file size should I expect after converting PUB to CFG?

CFG files are typically 2-5x larger than equivalent PUB files because CFG preserves all pixel data. This is expected and necessary for lossless quality.
