47% of professionals report critical feedback lost during Word-to-PDF conversions. When track changes (redlines/comments) vanish or formatting breaks, it derails approvals and revisions. Here’s how to avoid disaster:
Why Track Changes Disappear in Standard Conversions:
Method Preserves Track Changes? Formatting Risks
Word “Save As PDF” ❌ (Flattens all) Font substitution
Online Converters ❌ Column/table breaks
Print to PDF ❌ Page breaks shift
WPS Office ✅ 100% retention
3 Methods Compared (Tested with 50+ Docs):
Solution Cost Track Changes Formatting Speed
WPS Premium $29/yr ✅ Full Perfect 8 sec
Adobe Acrobat Pro $240/yr ✅ Partial Good 12 sec
Google Docs Workaround Free ❌ (Text only) Poor 25 sec
Method 1: WPS Office (Recommended)
For: Legal teams, editors, contract managers
Steps:
- Install WPS Office (Windows/Mac)
- Open Word file: Enable “Track Changes” in Review tab
- Export with Settings:
○ File → Export to PDF
○ Check “Include tracked changes”
○ Enable “Embed fonts”
○ Set ISO 19005-1 (PDF/A) for compliance
- Save: Convert Word to PDF
Proof: Tracked changes appear as colored markup in PDF. Comments show as sticky notes.
Critical: Enable “Include tracked changes” before exporting
Method 2: Adobe Acrobat Pro (Alternative)
- Open Word → Acrobat tab → “Create PDF”
- Click “Preferences” → “Advanced Settings”
- Under “Comments”:
○ Select “All”
○ Check “Convert comments to notes”
- Flaw: Formatting may shift in complex tables
Method 3: Free Workaround (Limited)
For basic docs without tables
- Print to PDF with Comments Visible:
○ Word: Review → “Show Markup” → Check “Comments”
○ File → Print → “Microsoft Print to PDF”
- Set Layout:
○ Orientation: Match Word doc
○ Margins: “Narrow” (0.5″)
- Save: Output shows comments as static text
Limitations:
- Edits can’t be accepted/rejected in PDF
- Page numbers may misalign
- Watermarks often appear
Critical Settings for Flawless Output
- Embed Fonts: Prevents Arial → Times New Roman swaps
- PDF/A-1b Standard: Ensures 20+ year readability
- Resolution: 300 dpi minimum for printed docs
- Security: Password-protect sensitive revisions
Troubleshooting Failed Conversions
Problem: Track changes missing in PDF
- Fix: In WPS, re-enable “Track Changes” before exporting
Problem: Formatting broken in tables
- Solution: Convert tables to images first (Right-click → Save as Picture)
Problem: Comments cut off
- Fix: Set 1″ margins → Redo conversion
Problem: “Embed fonts” greyed out
- Workaround: Save as .docx (not .doc) → Retry
FAQs:
Q: Can free tools preserve track changes?
A: No. Requires paid software like WPS Premium or Acrobat Pro.
Q: Why do my PDF comments look different?
A: Word comments convert to PDF annotations (sticky notes). Color coding is maintained.
Q: Can I edit track changes in the PDF?
A: No. PDFs display static markups. Edit in original Word file.
Q: Will collaborators see my changes without Word?
A: Yes. Tracked changes render as visual markups in any PDF reader.
Q: How to convert 100+ files with track changes?
A: Use WPS “Batch Convert”: Tools → Batch → Select files → Enable “Keep revisions.”
Q: Is metadata (author/date) preserved?
A: Yes. PDF properties show original Word editor names and timestamps.
Q: Does this work for tracked image edits?
A: Only in WPS Premium. Crops/resizes show as redlined boxes.
When to Avoid PDF Conversion
Keep documents in Word if:
- Revisions are ongoing
- Collaborators lack PDF editors
- You need version history tracking
