Questions
Is it safe to merge PDFs here?
Yes. The files are combined in your browser and never uploaded, so nobody else gets a copy. It works the same for contracts, invoices and ID scans.
Will the pages look the same?
Yes. Pages are copied as they are: text stays selectable, and fonts and links are kept. Bookmarks of the original files are not carried over, and fillable form fields may stop working in the merged file.
Is there a limit?
Up to 20 files of 100 MB each per merge, with no page limit. For more files, merge them in steps or use the File Acture app.
Can I merge password-protected PDFs?
Not here: a protected PDF can't be read without its password. Remove the password first (the File Acture app does it with Unlock PDF), then merge.
