Frequently Asked Questions About Our PDF Tools
Are my PDF documents safe?
Absolutely. Files are never uploaded anywhere. All merging, splitting, and rendering operations run 100% inside your browser tab.
What is the file size limit?
There is no imposed limit. The practical cap is your device's available RAM. We recommend keeping individual files under 100MB for best performance.
Can I reorder files before merging?
