About Merge PDF
Merge PDF combines two or more PDF files into a single document. Add your files, arrange them in the order you want by dragging the cards (or with the arrow buttons), and download one merged PDF. The pages are copied directly from your originals rather than re-rendered, so text stays sharp and selectable and images keep their original quality.
You may know this as a PDF merger, or search for ways to join PDF files or merge PDF files from a scan batch. Whatever you call it, the job is the same: many documents in, one tidy PDF out.
Everything happens in your browser. Your files are read from your device, combined in memory and handed back to you as a download — nothing is uploaded. That makes it a good fit for contracts, statements and application documents that you would rather not send to a third-party server.
Tips
- Name files with numeric prefixes (01, 02, 03) so the order is obvious.
- Form fields, bookmarks and internal links in the originals may not carry over to the merged file.
- Need it smaller afterwards? Run the result through Compress PDF. Read our guide to merging PDFs for more advice.
Guides for Merge PDF
Good to know
Is there a limit to how many files I can merge?
There is no fixed limit. Because merging happens in your browser, the practical limit is your device’s memory.
Are my files uploaded anywhere?
No. Your PDFs are processed on your own device and never sent to a server.
Can I merge PDFs with different page sizes?
Yes. Every page keeps its original size and orientation, so A4 and US Letter pages can sit in the same document.
Will the merged PDF lose quality?
No. Pages are copied as they are, not re-rendered, so text stays sharp and selectable and images keep their resolution.
Is it free?
Yes — completely free, with no sign-up and no watermarks added by us.
