Organizing Your Digital Filing Cabinet

Merging PDFs isn't just about sticking files together—it's about creating a clean, professional digital footprint.

Project Archives:
Instead of sending a client 15 separate attachments (Quote, Specs, Contract, etc.), merge them into one "Client_Name_Project_Master.pdf". It looks professional and ensures they don't lose a file.
Tax Season:
Scan all your receipts for the month and merge them into a single "January_Expenses.pdf". This makes sharing with your accountant remarkably simple.
E-Books & Manuals:
If you have scanned chapters of a book or separate pages of a manual, combine them to create a seamless reading experience.

Tips for Seamless PDF Merging

Best Practices

Same Page Size: Ideally, merge PDFs with similar page dimensions (e.g., all A4 or Letter) for the most professional look.
Check File Names: Naming your files sequentially (e.g., "1-Intro.pdf", "2-Body.pdf") makes ordering them drag-and-drop easy.
Compress First: If your source files are huge, try compressing them individually with our PDF Compressor before merging to keep the final file manageable.

Troubleshooting

Password Protection: You cannot merge encrypted PDFs. Please use our "Unlock PDF" tool first to remove passwords.
Corrupted Files: If the merge fails, one of your input files might be corrupted. Try opening them individually to check.
Javascript Required: Ensure Javascript is enabled in your browser, as our secure client-side engine relies on it.
