Frequently asked questions
Do my PDFs get uploaded?
No. The entire merge runs in-browser; files never leave your device.
Is there a count or size limit?
No hard limit — only your device's available memory. Merging dozens of multi-MB PDFs works fine.
Will bookmarks, links, and form fields survive?
Page content is preserved. Some bookmarks and interactive forms may need to be re-added due to pdf-lib limitations.
Can I merge password-protected PDFs?
Remove the password in a PDF reader first, then merge.
