10 Common PDF to Kindle Conversion Mistakes (And How to Fix Them)
By CreatorFormat Team
TL;DR: The most common PDF to Kindle conversion mistakes are: not converting to EPUB format, ignoring font embedding issues, skipping table of contents, using scanned PDFs, and uploading files with DRM protection. Use CreatorFormat's PDF to Kindle converter to automatically fix these issues and get KDP-ready files in minutes.
You've spent months writing your book, but when you convert your PDF to Kindle format, everything looks wrong. Text overlaps, images disappear, fonts change randomly, and the table of contents doesn't work.
Sound familiar?
PDF to Kindle conversion mistakes are incredibly common—even experienced authors make them. This guide identifies the 10 most frequent errors and shows you exactly how to fix them.
Why PDF to Kindle Conversion Fails
Before diving into specific mistakes, understand why PDFs are problematic for Kindle:
- Fixed layout: PDFs lock content position, but Kindles need reflowable text
- Embedded fonts: Kindle has limited font support
- Complex formatting: Multi-column layouts break on small screens
- Large file sizes: PDFs are 10x bigger than EPUBs
- Poor metadata: PDFs rarely include proper ebook metadata
The solution? Convert PDF to EPUB format first, then upload to Amazon KDP.
Mistake #1: Not Converting PDF to EPUB
The Problem:
Uploading PDFs directly to Amazon KDP creates a terrible reading experience:
- Text doesn't reflow to fit screen
- Readers must zoom and scroll constantly
- Font size can't be adjusted
- Poor battery life (more screen refreshes)
- Negative reviews mentioning "unreadable formatting"
The Fix:
✅ Convert PDF to EPUB before uploading
How to Fix:
- Use CreatorFormat's PDF to Kindle Converter
- Upload your PDF file
- Click "Convert to EPUB"
- Download the optimized EPUB
- Upload EPUB to Amazon KDP
Amazon automatically converts EPUB to Kindle format (AZW3/KFX) with proper text reflow and font support.
Impact: 73% of readers abandon ebooks with poor formatting (Publisher's Weekly, 2024).
Mistake #2: Using Scanned PDFs Instead of Text PDFs
The Problem:
Scanned PDFs are essentially images of pages, not actual text. Kindle treats them as large image files:
- No text selection or highlighting
- Can't adjust font size
- No searchable text
- Accessibility features don't work (screen readers fail)
- Massive file sizes (50-100MB+)
How to Identify Scanned PDFs:
Try to select text in your PDF. If you can't, it's a scanned image.
The Fix:
✅ Use OCR (Optical Character Recognition) to extract text
How to Fix:
Option 1: Use Adobe Acrobat
- Open PDF in Adobe Acrobat Pro
- Tools → Enhance Scans → Recognize Text
- Select "In This File"
- Save as searchable PDF
- Convert to EPUB using CreatorFormat
Option 2: Use Free Online OCR
- Upload to OCR.space or Google Docs
- Let it extract text
- Export as DOCX
- Convert DOCX to EPUB
Pro Tip: Modern scanners have built-in OCR. Always use OCR when scanning documents.
Mistake #3: Ignoring Font Embedding Issues
The Problem:
Your PDF uses custom fonts not available on Kindle devices:
- Fonts revert to default (Times New Roman or Bookerly)
- Inconsistent appearance across devices
- Broken special characters
- Line spacing looks wrong
The Fix:
✅ Use Kindle-safe fonts or embed properly
Kindle-Safe Fonts:
- Bookerly (Kindle default)
- Times New Roman
- Arial
- Georgia
- Verdana
- Courier
How to Fix:
For PDFs:
- Open in Adobe Acrobat
- File → Properties → Fonts
- Check if fonts are embedded
- If not, re-export PDF with embedded fonts
Better Solution: Convert to EPUB—fonts automatically fallback to Kindle-supported options.
Use PDF to EPUB converter to let Amazon handle font substitution properly.
Mistake #4: Missing or Broken Table of Contents
The Problem:
Readers tap "Go To" on Kindle and see:
- No table of contents
- Table exists but links don't work
- TOC shows page numbers instead of chapters
- Broken navigation
Amazon KDP requires a working TOC for publication approval.
The Fix:
✅ Create an interactive, HTML-based table of contents
How to Fix:
Option 1: Use CreatorFormat (Easiest)
- Upload PDF to CreatorFormat
- Tool auto-detects chapters from headings
- Generates working TOC automatically
- Download with interactive navigation
Option 2: Manual with Calibre
- Open PDF in Calibre
- Edit Book → Tools → Table of Contents
- Detect chapters or add manually
- Generate TOC from headings
- Save and export
Option 3: In Original Document
- Use heading styles (Heading 1, Heading 2) in Word/Google Docs
- Insert automatic TOC
- Export as PDF
- Convert to EPUB
Amazon Requirement: All KDP ebooks must have a working table of contents with clickable chapter links.
Mistake #5: Uploading Files with DRM or Password Protection
The Problem:
Your PDF has:
- Password protection
- DRM (Digital Rights Management)
- Print restrictions
- Copy restrictions
Amazon KDP rejects these files immediately.
The Fix:
✅ Remove DRM and passwords before conversion
How to Fix:
For Password-Protected PDFs:
- Open in PDF reader
- Enter password
- File → Print → Save as PDF (without password)
- Use the new unprotected PDF
For DRM-Protected PDFs:
- DRM removal is complex and often illegal
- Only remove DRM from files you own
- Use Calibre + DeDRM plugin for personal files
- Never remove DRM from copyrighted material you don't own
Legal Note: Only remove DRM from content you legally own. Removing DRM from others' content may violate copyright laws.
Mistake #6: Not Optimizing Images for Kindle
The Problem:
Your Kindle book has:
- Blurry, pixelated images
- Huge file size (over 50MB)
- Images that don't display
- Slow loading times
- Delivery fees (Amazon charges per MB)
The Fix:
✅ Optimize images to 300 DPI for print, 72 DPI for digital
Image Guidelines:
| Aspect | Kindle Requirement |
|---|---|
| Resolution | 72-150 DPI for screen display |
| Format | JPG or PNG (no GIF or BMP) |
| Color Space | RGB (not CMYK) |
| Max Size | Under 5MB per image |
| Total Book Size | Under 650MB |
How to Fix:
Using Photoshop/GIMP:
- Image → Image Size
- Set resolution to 150 DPI
- Set width to 600-800 pixels (Kindle screen width)
- Export as JPG with 80% quality
Using Online Tools:
- Upload to TinyPNG
- Compress images
- Download optimized versions
- Replace in your PDF
Automatic Option: CreatorFormat automatically optimizes images during conversion.
Amazon Delivery Fee: Amazon charges $0.15 per MB for delivery. A 50MB book costs $7.50 per sale in delivery fees!
Mistake #7: Keeping Multi-Column or Complex Layouts
The Problem:
Your PDF has:
- 2-column magazine layout
- Sidebars and callout boxes
- Text wrapping around images
- Complex tables
Kindle can't handle these layouts. Text appears jumbled, columns overlap, and reading order breaks.
The Fix:
✅ Simplify to single-column, linear layout
How to Fix:
Before Creating PDF:
- Remove multi-column layouts
- Convert sidebars to regular paragraphs
- Place images between paragraphs (not wrapped)
- Simplify complex tables
For Existing PDFs:
- Use CreatorFormat to linearize content
- Tool automatically converts multi-column to single-column
- Reflows content for Kindle reading
Kindle Best Practice: Always use single-column, top-to-bottom reading flow.
Mistake #8: Ignoring Metadata and Book Information
The Problem:
Your converted Kindle book shows:
- "Unknown Author"
- Generic title ("Document.pdf")
- No book description
- Missing publication date
- No ISBN or ASIN
This hurts discoverability on Amazon.
The Fix:
✅ Add complete metadata before uploading
Required Metadata:
- Book title
- Author name
- Publisher
- Publication date
- ISBN (optional but recommended)
- Language
- Categories/keywords
How to Fix:
In EPUB (Recommended):
- Use Calibre → Edit Book → Edit Metadata
- Fill in all fields
- Save and upload to KDP
In Amazon KDP Dashboard:
- Enter all metadata during upload
- Don't rely on metadata in PDF
- KDP dashboard overrides file metadata
With CreatorFormat:
- Add metadata during conversion
- Automatically included in EPUB output
Mistake #9: Not Testing on Actual Kindle Devices
The Problem:
Your book looks perfect on your computer, but on Kindle:
- Line breaks appear randomly
- Text runs off the screen
- Images are misplaced
- Navigation doesn't work
Different Kindle devices display content differently.
The Fix:
✅ Test on multiple Kindle devices and apps before publishing
Testing Tools:
1. Kindle Previewer (Free from Amazon)
- Download from Amazon's website
- Tests on all Kindle device types
- Shows how your book looks on different screens
- Available for Windows and Mac
2. EPUB Viewer (Online)
- Use CreatorFormat's EPUB Viewer
- Instant preview in browser
- No software installation
- Quick formatting checks
3. Physical Kindle Devices
- Test on actual Kindle, Kindle Paperwhite, etc.
- Check on Kindle app (iOS and Android)
- Read at least 3-4 chapters
- Test all navigation features
Amazon Recommendation: Always preview your book using Kindle Previewer before publishing.
Mistake #10: Skipping Amazon KDP Formatting Guidelines
The Problem:
Your book gets rejected by Amazon KDP because:
- Doesn't meet technical specifications
- Missing required elements (TOC, copyright page)
- File size too large
- Invalid formatting
- DRM issues
The Fix:
✅ Follow Amazon KDP formatting guidelines exactly
Amazon KDP Requirements (2025):

| Table of Contents | Required, must be functional |

| DRM | None (Amazon adds its own) |
How to Fix:
Read Official Guidelines:
Use KDP-Approved Tools:

- Calibre with KDP export settings
