PDF Document Merging Principles
Understand how PDF streams, vector outlines, and embedded assets are joined together safely.
Lossless Page Copying
Merging copies raw PDF page structures directly into a new target catalog. Vector geometry, fonts, and high-resolution elements remain uncompressed and unaltered.
Order Fidelity
The pages inside each document remain in their original sequence, while documents themselves are combined strictly according to your customized merge order.
Password Protection Rules
OfficeKit processes files strictly in the client environment without decryption keys. Encrypted and password-protected files must have their restrictions unlocked before merging.
