How to use Merge PDF
- Choose two or more PDF files.
- Use the arrows to put the pages in order, and remove any you do not need.
- Press Merge PDF and download the combined file.
When merging helps
Applications often ask for “one PDF”: an ID, a bill and a signed form together. Merging also keeps a month of statements or the chapters of an assignment in one place, in the right order, so nothing is lost when you email it.
Order and quality
Pages are copied exactly as they are — text stays selectable and pictures are not re-compressed. Every page appears as a thumbnail, so you can check the order before joining, and turn a sideways scan upright on the way.
Other names for this job
People call this many things: combine PDF files, join PDFs, put two PDFs together, add pages to a PDF, or make one PDF from many. They are all the same job. Whether you need to merge two PDF files or twenty, combine scanned pages into one document, or join a PDF to another before emailing it, this PDF merger does it online, free, without installing software and without a watermark.
Free, private and without a watermark
Merge PDF runs in your browser, so the file is not uploaded and no watermark is added. You can open a file and try the tool without signing in. To download the result, create a free Bol Ke Likho account — an email address and a six-digit code, no password and no card.
Questions people ask
How many PDFs can I merge?
As many as your device’s memory allows. Very large jobs (hundreds of pages) work best on a computer rather than a phone.
Does merging reduce quality?
No. Pages are copied as they are, without re-compressing.
Are my files uploaded?
No. The merging is done by your own browser; the files are not sent to any server.
How do I combine two PDF files into one?
Choose both files, check the order of the pages, and press Merge PDF. The two PDFs are joined into one file that downloads straight away.
Can I merge PDF files on my phone without an app?
Yes. Open this page in your phone’s browser, choose the PDFs from your files, and merge them. Nothing needs to be installed.
Is Merge PDF free? Is there a watermark?
Yes, it is free, and no watermark is added to your file. You can try the tool without an account; a free Bol Ke Likho account is needed to download the result. No payment details are asked for.
Is it safe to use Merge PDF online here?
Your file is processed inside your own browser and is not uploaded to our servers, which is the main risk with online PDF tools. Close the page and nothing is kept.
