Frequently Asked Questions
Are there limits on how many PDFs I can merge?
No limit on file count. For very large batches (50+ files), merge in groups for best performance.
Are bookmarks and hyperlinks preserved?
Text, images and layout are fully preserved. Bookmarks and hyperlinks from originals may not always carry over.
Can I merge password-protected PDFs?
Remove the password first in Adobe Reader or Preview, then upload the unprotected version.
What about scanned PDFs?
Scanned PDFs merge perfectly. Text will not be searchable unless OCR has been applied.
Can I merge only specific pages?
Use the PDF Splitter first to extract the pages you need, then merge those extracted files.
