Merge PDF Tool

Why Merge PDFs?

Sometimes you end up with a bunch of separate PDF files that really belong together — maybe chapters of a document, pages of a form, or scanned pages you saved one at a time. Instead of sending ten different files, you can combine them into one clean PDF. Much easier for you, and for whoever you are sharing it with.

Situations Where This Helps

• Job Applications: Your CV, cover letter, and certificates are separate files. Merge them into one PDF to send as a single attachment.
• Contracts and Agreements: Combine a main contract with its annexures so everything is in one document.
• Scanned Documents: If you scanned a multi-page document one page at a time, merge all the pages back into one file.
• Reports: Put together monthly reports, charts, and supporting data pages into a single PDF for sharing.
• Study Notes: Merge lecture notes from different weeks into one revision document.

How to Merge Your PDFs

1. Click "Choose Files" and select two or more PDF files. You can select them all at once.
2. The list of selected files appears in the tool.
3. Click "Merge PDFs" — the files are combined in the order you selected them.
4. Watch the progress bar, then click "Download Merged PDF" when it is ready.

Good to Know

Q: Does the order matter?
A: Yes. The PDFs are merged in the order you select them. Pick your files in the order you want them to appear in the final document.

Q: How many files can I merge?
A: There is no hard limit. Just select all the files you need. Very large PDFs may take a moment to process.

Q: Are my files safe?
A: Yes. The merging happens in your browser using pdf-lib. Nothing is sent to any server.
