Combine PDF files into one online, free

PDF Vision combines your PDFs ENTIRELY in your browser: the files never leave your device to be merged. Add them, drag them into the order you want, and download the single document that comes out. The common reason is not tidiness but a form that accepts one attachment — an application, its annexes and its supporting documents have to arrive as one file — and professional sends where several documents should land bound together rather than as loose attachments. One free document a day with no account, more with a free account.

How to combine PDF files into one

  1. Add your files

    Drop several PDFs onto the upload zone, or pick them all at once.

  2. Set the order

    Drag the thumbnails: the order you see is the order of the finished document.

  3. Merge and download

    The single document is assembled in your browser, then downloaded.

Why use it

Nothing leaves your device

The merge runs locally. On supporting documents or contracts, that is the guarantee that matters most — there is no upload to worry about.

An order you control

The order you added the files in is not forced on you: rearrange them before merging instead of starting over.

One file to submit

Most administrative forms accept a single attachment. Merging saves you from choosing what to leave out.

Frequently asked questions

Are my files uploaded?
No. The merge runs entirely in your browser, so the documents never leave your device.
How many PDFs can I merge?
There is no fixed count, but the work happens in your browser’s memory: a very large batch on a modest device can slow down. Merge in two passes if that happens.
Can I change the order of the files?
Yes, by dragging the thumbnails before you merge. The order shown is the order you get.
Are bookmarks and links preserved?
Pages, their content and their layout are. Bookmarks and some internal links belonging to each source file may not survive the assembly.
Do I need an account?
One free document a day without an account. A free account lifts that limit.
Can I merge a password-protected PDF?
No. An encrypted document has to be unlocked first — with the password you already hold — before it can be assembled.
Is there a size limit?
No ceiling is applied here, because nothing is uploaded. The real constraint is that every file you add is held in your browser’s memory at once, so what matters is their combined size rather than any single document. If a large batch stalls on a phone or an older laptop, merge half, then merge the two halves.
