About Merge PDF

Merge PDF files when a portal takes one upload and you have five: a signed contract and its annexes, a visa application with bank statements, a pile of receipts for an expense claim. Add the files, drag the cards into order or press Sort by name, and they come out as a single PDF. Each card shows its page count, so you can check nothing is missing.

With Add a bookmark for each file switched on, the merged PDF gets a bookmark named after every source file, and bookmarks already inside those files come along too. Pages are copied as they are, so text stays selectable and nothing is redrawn. The finished file is named after the first one, like merged_contract.pdf, unless you type your own name.

How to use Merge PDF

  1. 1
    Add your PDFs

    Click Choose files or drop the PDFs on the page. You need at least two.

  2. 2
    Put them in order

    Drag the cards into place, or press Sort by name so part-2 comes before part-10.

  3. 3
    Check the options

    Leave Add a bookmark for each file on if you want one per file. Under More options you can name the merged file.

  4. 4
    Merge and download

    Click Merge PDF and save the combined document.

Why use Cubfile for this

  • Any order you like

    Drag files around or sort them by name, with numbers read the way people read them, so chapter-9 comes before chapter-10.

  • A bookmark per file

    Every source file becomes a bookmark in the merged PDF, and the bookmarks it already had are carried over.

  • Pages copied, not redrawn

    Text stays selectable and images keep their resolution, because each page goes into the new file unchanged.

  • Up to 50 files at once

    Free and guest users combine up to 20 PDFs per task. VIP raises that to 50, each file up to 1 GB.

FAQ

Merge PDF: questions and answers

Will my pages lose quality when I merge PDF files?
No. Each page is copied into the new document as it is, so text stays sharp and pictures are not recompressed. If the merged file is too big to send, run it through Compress PDF afterwards.
How many PDFs can I combine for free?
Up to 20 per task, each up to 50 MB. Visitors get 2 tasks in total and free accounts 2 a day, while VIP has no daily limit and takes up to 50 files of up to 1 GB each.
Can I merge PDF files on my phone?
Yes. Open this page in Safari or Chrome, tap Choose files and pick the PDFs from Files or Downloads. Add them in the order you want, or use Sort by name.
Can I merge PDF files that have a password?
PDFs that open without a password but block printing or copying merge normally. If a file asks for a password when you open it, take the password off first, then add it here. You can do that with Unlock PDF, as long as you know the password.
What happens to my files after merging?
They travel over HTTPS, are merged in an isolated process and are deleted automatically after one hour. If you'd rather not wait, press Delete my files now on the result screen.
