Frequently Asked Questions
This is a PDF Optimizer that works 100% in your browser. While it doesn't provide the same level of compression as server-based tools (like Adobe Acrobat or online services), it offers:
- Security: Files never leave your computer
- Privacy: Perfect for confidential documents
- Free: No limits, no subscriptions
- 5-60% reduction depending on PDF content
The maximum recommended file size is 50MB. However, the actual limit depends on:
- Your computer's memory: Larger files require more RAM
- Browser capabilities: Some browsers handle large files better than others
- Processing time: Very large files may take several minutes
Tip: For PDFs larger than 50MB, consider splitting them first using our PDF Splitter tool.
