How to Fix a PDF That Freezes When Splitting or Reducing File Size
Question details
The user needs to resolve an issue where the PDF software freezes or crashes during document optimization or splitting.
- Product
- PDF Editor
- Device & OS
- not provided
- Scenario
- Attempting to split a PDF into multiple files or compress it to reduce the overall file size.
- Observed behavior
- The application freezes, lags severely, or throws an array-related error, preventing the split or compression process from completing.
Test processing a different PDF file first to determine if the freezing issue is caused by your software or if it is isolated to that specific damaged or overly complex document.
Flatten the PDF by Printing to PDF
This method removes complex interactive elements, hidden layers, and corrupted background data that often cause processing tools to freeze.
PDFs with damaged internal structures or unsupported document data can overwhelm the software's processing engine. Flattening the file creates a fresh, clean PDF structure that is much easier to split or compress.
Launch your PDF editor or viewer and open the file that is freezing.
Go to 'File' in the top menu bar and select 'Print', or press Ctrl+P (Windows) / Cmd+P (Mac).
In the Printer drop-down menu, choose 'Microsoft Print to PDF' or your software's built-in PDF printer.
Click 'Print' and save the newly generated file with a different name. Try splitting or compressing this new file.
Clear Software Cache and Update the Application
Outdated software or corrupted temporary files can cause lagging and freezing during intensive tasks like PDF optimization.
Split and Compress Complex PDFs Smoothly with WPS Office
If your current PDF software freezes or displays errors during file optimization, switch to WPS Office. Its powerful PDF engine handles complex, large, or slightly damaged files efficiently, allowing you to split pages or reduce file sizes without frustrating lag.
- 1. Open the PDF in WPS Office: Launch WPS Office and open your complex or large PDF document.
- 2. Split the PDF: Navigate to the 'Page' tab on the top ribbon and click on 'Split PDF' to divide your document safely.
- 3. Compress the PDF: To reduce the file size without freezing, go to the 'Tools' tab and select 'Compress' to optimize the document instantly.
Frequently Asked Questions
Why does my PDF freeze only when I try to split it?
Splitting a PDF requires the software to rewrite the document's internal structure. If the file contains corrupted metadata, overly complex vector graphics, or embedded fonts, it can overload the software's processing capabilities and cause it to freeze.
What does an array-related error mean in a PDF?
An array-related error typically indicates that the document's internal object tree (the code defining page order and elements) is damaged. When the software attempts to parse or divide this array of pages during a split, the corrupted code causes the operation to fail.
Will reducing the PDF file size lower its quality?
It depends on your compression settings. Most PDF compressors reduce size by downsampling images and removing unnecessary background data. While this may cause a slight drop in image resolution, the text will remain sharp and fully readable.
