Frequently asked questions
Is there a limit on how many PDFs I can merge?
No fixed count limit β the practical constraint is file size: each input can be up to 10 MB on the free tier (100 MB with Premium). Twenty small PDFs merge just as easily as two.
Will bookmarks, links, and form fields survive the merge?
Page content β text, images, vector graphics β is preserved exactly. Document-level extras like bookmarks and interactive form fields are not carried over, since they live outside the pages being copied.
Can I merge password-protected PDFs?
No. Encrypted files cannot be opened for copying. Remove the password in your PDF reader first, then merge.
Does merging reduce quality or re-compress my pages?
No. Pages are copied at the object level rather than being rasterized, so a 300-DPI scan stays a 300-DPI scan and vector text stays vector.
Your files stay private
All input PDFs are held in memory only for the duration of the merge and are gone the moment your download starts. Nothing is written to disk, logged, or shared. Signed-in users get a history entry with file sizes only.
