Frequently Asked Questions

What does it mean to resize a PDF file?

Resizing a PDF can mean two things: reducing the file size (compression) or changing the page dimensions. Our tool does both! Use file size mode for smaller documents, or dimension mode to change page size.

Is it safe to upload my PDF file?

Absolutely. All processing happens locally in your browser. Your files never leave your device, ensuring complete privacy for sensitive documents like contracts, financial statements, and personal information.

What's the maximum file size I can resize?

You can upload PDF files up to 100MB. For larger files, consider splitting them first.
