Merge PDF →Frequently Asked Questions
Is joining PDFs the same as merging?
Yes. 'Join', 'merge', 'combine', and 'concatenate' all describe the same operation — taking two or more PDF files and combining them end-to-end into one document.
Are watermarks added to the joined PDF?
No. PDF Mavericks never adds watermarks, branding, or any modification to your documents.
What is the maximum file size for joining PDFs?
Each individual PDF can be up to 100MB. The practical total size limit depends on your device's available browser memory.
