Merge PDF

What Merge PDF does

Merge PDF combines multiple PDF files into a single PDF document, processed entirely in your browser so your files are never uploaded to a server.

How to use it

1. Choose multiple PDF files, selected in the order you want them combined.
2. Review the file list shown.
3. Click Merge PDFs and download the combined file.

Common uses

• Combining several scanned document pages into one PDF for submission.
• Merging separate chapter or section PDFs into a single complete document.
• Combining an invoice with supporting receipts into one file for expense reporting.
• Merging multiple signed contract pages into a single final document.
• Consolidating a batch of related PDFs before archiving or sharing.

Good to know

Files are combined in the exact order you selected them in the file picker, so if you need a specific final order, select or reorder your files accordingly before clicking merge — the tool doesn't reorder files automatically based on filename or content.

Combining PDFs used to require dedicated desktop software with licensing costs, largely because manipulating the PDF format correctly is more involved than it might seem — modern browser-based JavaScript libraries have made this kind of document manipulation accessible without installing anything, which is exactly what makes a tool like this practical for a one-off task.
