Fix: Word Extremely Slow with Large Documents

Why Large Documents Slow Down Word

Word loads the entire document into memory and processes it continuously. The larger the file, the more resources it needs.

Pasos para solucionar

Step 1: Switch to Draft View

Draft view is significantly faster than Print Layout:

1. Go to View > Draft
2. Images appear as placeholders, reducing rendering load
3. Use Print Layout only when you need to check final formatting

Step 2: Disable Background Proofing

1. Go to File > Options > Proofing
2. Uncheck Check spelling as you type
3. Uncheck Mark grammar errors as you type

Step 3: Compress All Images

1. Click any image in the document
2. Go to Picture Format > Compress Pictures
3. Select Apply to all pictures in this document
4. Choose 150 ppi (good for printing) or 96 ppi (screen only)
5. Check Delete cropped areas of pictures
6. Save the document

Step 4: Use Master Documents

For very long documents (dissertations, reports):

1. Go to View > Outline
2. Use Show Document in the Master Document group
3. Break your document into subdocuments by chapter
4. Each subdocument is a separate file that loads on demand

Step 5: Remove Unused Styles and Formatting

1. Press Ctrl+A to select all
2. Go to Home > Styles and apply Normal to clear overrides
3. Reapply only the styles you need

Prevención Tips

• Insert images as linked files instead of embedded when possible
• Use paragraph styles instead of manual formatting
• Avoid excessive use of text boxes and shapes
• Save in .docx format (not .doc) for better compression
