How to use Merge PDF
- Select or drag two or more PDF files.
- Use the arrows to put the files in the order you want.
- Click Merge PDF and download the combined document.
Why merge PDF files?
Merging keeps related documents together: invoices for a month, scanned pages of a contract, or certificates for a job application. One file is easier to send, upload and archive.
Original quality is kept
Pages are copied exactly as they are. Text stays selectable, links keep working and no quality is lost.
Tips for merging PDFs
Name your files in the order you want them (for example 01-cover.pdf, 02-invoice.pdf) before selecting them, then fine-tune with the arrows. If the merged file is too large to email, run it through Compress PDF afterwards. To combine photos with PDFs, convert the photos first with JPG to PDF.
Frequently asked questions
Can I merge password-protected PDFs?
Files with an open password cannot be read until the password is removed in a PDF reader. Files with only editing restrictions usually merge fine.
Is there a page limit?
No fixed limit. Very large merges depend on your device's memory; computers handle more than phones.
How many PDFs can I merge at once?
There is no fixed limit. You can merge as many files as your device memory can handle — usually dozens of documents.
Can I change the order of pages?
You can reorder whole files before merging. To remove or extract specific pages, use the Split PDF tool first.
Are my files uploaded to a server?
No. Everything is processed directly in your browser using JavaScript. Your files never leave your device, so they stay completely private.
Is this tool really free?
Yes. It is 100% free with no sign-up, no watermark and no limit on how many times you use it.
