Word to PDF Best Practices for Pixel-Perfect Output

You sent a polished Word document to a client. They opened it on a different OS, with a different version of Word, and watched your carefully aligned tables collapse, your custom fonts fall back to Calibri, and your margins shift by half an inch. PDF was invented to solve exactly this problem.

The five rules

1. Embed fonts. If the converter offers a “subset all fonts” option, take it. The recipient sees the file with your typography, not theirs.
2. Resolve tracked changes first. Accept or reject every change in Word before exporting; tracked changes can survive into PDF as comments or worse.
3. Flatten form fields if not interactive. If your PDF doesn’t need fillable fields, flatten them. They’re a frequent source of rendering quirks.
4. Match output to purpose. Print-bound PDF: 300 dpi images, CMYK colourspace, no compression. Email-bound: 150 dpi, RGB, lossy compression.
5. Verify on a different device. Open the PDF on a phone and another computer before sending. Catches font issues that don’t show on the originating machine.

What Word’s built-in export gets wrong

Microsoft’s “Save As PDF” works for everyday docs, but it sometimes:

• Skips font embedding for “system” fonts you customised.
• Inflates file size by storing images at the original camera resolution.
• Loses hyperlink targets in cross-references.

A purpose-built converter handles these consistently across input variations.

For batch conversion

If you regularly convert dozens of Word files (reports, invoices, certificates), batch conversion with a saved preset eliminates the per-file tweaking. Defaults stay correct across the run, and the output is byte-consistent across files — useful when downstream tools (printers, ATS systems, client portals) check file properties.
