Common File Conversion Problems and How to Fix Them

Problem 1: Garbled or Incorrect Text After OCR

Symptoms: The converted text has random characters, wrong words, or unreadable output.

Causes:

• Low-resolution image or scan
• Poor contrast (gray text, colored paper)
• Unusual or decorative fonts
• Watermarks overlapping text

Solutions:

• Re-scan at 300 DPI in black and white
• Adjust contrast before converting
• For watermarked documents, try digitally enhancing contrast first

Problem 2: Missing Pages or Content

Symptoms: Some pages are missing from the converted output.

Causes:

• Corrupted PDF pages
• Password-protected PDFs (protected content can't be extracted)
• Very large files causing memory issues

Solutions:

• Remove password protection first
• Try converting specific page ranges
• Split large PDFs before converting

Problem 3: No Text Extracted from PDF

Symptoms: Tool runs but outputs empty text.

Causes:

• PDF is purely image-based (scanned) and OCR wasn't applied
• PDF is encrypted or has restricted permissions

Solutions:

• Use a tool with OCR support (like ConvertIQ's PDF to Text or PDF to Word)
• Remove password protection before converting

Problem 4: Incorrect Document Formatting in DOCX Output

Symptoms: Tables are missing, text is out of order, columns are wrong.

Causes:

• Complex PDF layouts don't convert perfectly
• Tables and multi-column content are hard to reconstruct

Solutions:

• Accept that some manual cleanup is needed
• Use PDF to Text first to verify content is readable, then paste into Word
• For critical formatting, consider manually recreating the layout in Word

Problem 5: Conversion Stalls or Doesn't Complete

Symptoms: Progress bar stops, browser freezes, or nothing happens.

Causes:

• Very large file
• Insufficient device memory
• Older browser without full WebAssembly support

Solutions:

• Use a modern browser (Chrome, Firefox, Edge)
• Try a smaller or lower-resolution file
• Close other browser tabs to free memory
• Refresh the page and try again
