10 Common PDF Problems and How to Fix Them
PDFs are everywhere in our digital world, but they're not without their problems. From files that won't open to formatting nightmares, PDF issues can be incredibly frustrating. Here's your complete guide to solving the most common PDF problems quickly and effectively.
Before You Start
Always keep backup copies of important PDFs before attempting any fixes. Some solutions may modify the original file, and you'll want to preserve the original in case something goes wrong.
1. PDF Won't Open or Displays Error Messages
The Problem: You double-click a PDF file, but it won't open, shows an error message, or displays a blank screen.
Solutions:
Update your PDF reader
Outdated PDF readers often can't handle newer PDF formats. Update Adobe Reader, Chrome, or your preferred PDF viewer.
Try a different PDF reader
If Adobe Reader fails, try opening the file in Chrome, Firefox, or alternative readers like Foxit or Sumatra PDF.
Re-download the file
The file might be corrupted during download. Try downloading it again from the original source.
2. PDF File Size is Too Large
The Problem: Your PDF is too large to email, upload, or share, making it impractical for everyday use.
Solutions:
Use our PDF compression tool
Our PDF compressor can reduce file sizes by 60-80% while maintaining quality.
Optimize images within the PDF
Large images are often the culprit. Reduce image resolution and quality for web sharing.
Remove unnecessary elements
Delete unused bookmarks, comments, form fields, and embedded fonts that aren't essential.
3. Text is Blurry or Pixelated
The Problem: Text appears fuzzy, pixelated, or difficult to read, especially when zooming in.
Solutions:
Check your zoom level
Sometimes the issue is simply viewing at an inappropriate zoom level. Try 100% or 125% zoom.
Enable font smoothing
In Adobe Reader, go to Edit > Preferences > Page Display and enable "Smooth text and monochrome images."
Recreate from source
If possible, recreate the PDF from the original document with higher quality settings.
4. PDF Pages Won't Print Correctly
The Problem: Pages print with cut-off content, wrong orientation, or scaling issues.
Solutions:
Adjust print scaling
In print dialog, try "Fit to page," "Actual size," or "Shrink oversized pages" options.
Check page orientation
Ensure your printer settings match the PDF orientation (portrait vs. landscape).
Print as image
In advanced print options, select "Print as image" to bypass font and vector rendering issues.
5. Can't Copy or Select Text
The Problem: You can't select, copy, or search text within the PDF, making it difficult to extract information.
Solutions:
Check if it's a scanned document
Scanned PDFs are essentially images. You'll need OCR (Optical Character Recognition) to make text selectable.
Use OCR tools
Adobe Acrobat Pro, Google Drive, or online OCR tools can convert image-based text to selectable text.
Check security restrictions
The PDF might have copy protection enabled. Look for a lock icon in your PDF reader.
6. PDF Forms Won't Save or Submit
The Problem: You fill out a PDF form, but your entries disappear when you reopen the file, or the form won't submit.
Solutions:
Save with a new name
Use "Save As" instead of "Save" to create a new file with your form data preserved.
Use Adobe Reader
Some forms only work properly in Adobe Reader. Avoid browser PDF viewers for complex forms.
Check form permissions
The form might not allow saving. Try printing to PDF to preserve your entries.
7. Password-Protected PDF Won't Open
The Problem: You have the password, but the PDF still won't open, or you've forgotten the password entirely.
Solutions:
Check password accuracy
Passwords are case-sensitive. Try typing in a text editor first to verify, then copy-paste.
Contact the sender
If you received the PDF from someone else, they might have the password or can send an unprotected version.
Password recovery tools
Only use these for PDFs you own. Password cracking may violate terms of service or laws.
8. PDF Displays Incorrectly on Mobile Devices
The Problem: PDFs look fine on desktop but are difficult to read or navigate on smartphones and tablets.
Solutions:
Use mobile-friendly PDF readers
Adobe Acrobat Reader mobile app offers better mobile viewing than browser PDF viewers.
Enable reflow mode
Many mobile PDF readers have a "reflow" or "liquid mode" that reformats text for smaller screens.
Convert to mobile-friendly format
Consider converting to images or creating a mobile-optimized version of the PDF.
9. PDF Loading is Extremely Slow
The Problem: PDFs take forever to load, especially large documents or those with many images.
Solutions:
Compress the PDF
Use our PDF compression tool to reduce file size and improve loading speed.
Enable fast web view
When creating PDFs, enable "Fast Web View" to allow page-by-page loading instead of downloading the entire file.
Split large PDFs
Use our PDF splitter to break large documents into smaller, faster-loading sections.
10. PDF Compatibility Issues Between Different Readers
The Problem: A PDF looks different or has missing elements when opened in different PDF readers or browsers.
Solutions:
Use standard fonts
Stick to common fonts like Arial, Times New Roman, or embed fonts in the PDF to ensure consistency.
Save as PDF/A
PDF/A format ensures long-term compatibility and consistent rendering across different readers.
Test across multiple readers
Before distributing, test your PDF in Adobe Reader, Chrome, Firefox, and mobile apps.
