Merge PDF is a free tool that combines several PDF files into a single document. Add your files, put them in the right order, and download one PDF. The files are merged inside your browser and are never uploaded, so it is safe for contracts, statements and other private documents.
How to merge PDF files
- Drag your PDFs into the box, or tap Choose files. Add more at any time.
- Put them in order: drag a file up or down, or use the arrow buttons. The first file in the list comes first.
- Click Merge. The combined PDF downloads as
merged.pdf.
Common uses
- Combining a job application: cover letter, CV and certificates in one file.
- Joining scanned pages or receipts for an expense claim.
- Putting monthly bank or utility statements into a single file.
- Adding a signed page back into a contract.
Why merge PDFs in your browser?
Most online PDF tools upload your files to their servers to process them. This one does the work on your own device, so documents with personal or financial information never leave it. It also means there is no waiting for uploads, no file-count limits and no watermark.
Good to know
- Pages are copied exactly, with no loss of quality.
- Bookmarks and fillable form fields from the original files are not kept.
- Password-protected PDFs need their password removed first.
- To remove, reorder or rotate pages after merging, use Organize PDF. To add numbers to the combined document, use Add Page Numbers.
Frequently asked questions
Is my PDF uploaded?
No. The PDF is processed inside your browser, so it never leaves your device. That makes it safe for contracts, bank statements, medical letters and other private documents.
Is there a limit on files or size?
There is no fixed limit on the number of files. Very large PDFs (hundreds of megabytes in total) may run out of memory on phones; a computer handles much more.
Will the merged PDF keep links and bookmarks?
Pages keep their text, images and links. The bookmarks (outline) and form fields of the original files are not carried over.
Can I merge password-protected PDFs?
Not directly. Remove the password in your PDF app first, then merge.
Does it add a watermark?
No. The merged PDF contains only your pages.
