How it works

How to use the Merge PDF tool

  1. 1

    Add your PDFs

    Drop the files onto the upload area or click to browse. You can add up to 50 PDFs at once.

  2. 2

    Set the order

    Drag files up and down, or use the arrow buttons. Pages are combined top to bottom.

  3. 3

    Merge and download

    Click Merge PDFs. Your combined file is created instantly and downloads as a single PDF.

Why merge PDFs?

Many applications, from job portals to visa and university forms, accept just one file. Merging lets you send a CV, cover letter and certificates as one tidy document instead of a handful of attachments.

It also keeps related documents together: invoices for a month, scanned receipts for an expense claim, or chapters of a report exported separately.

What stays the same after merging

FreeToolsDaily copies pages as they are. Text stays selectable, images keep their original resolution and page sizes are preserved, so a mix of A4 and Letter pages stays a mix. Nothing is re-compressed or rasterized, and no watermark is added.

Limitations

We’d rather be upfront about what this tool can’t do yet:

  • Password-protected PDFs can't be merged until the password is removed.
  • Bookmarks (the outline panel) and interactive form fields from the source files aren't carried over into the merged document.
  • Very large merges are limited by your device's memory. Up to a few hundred MB in total works on most computers.

FAQ

Frequently asked questions

Are my PDF files uploaded to a server?

No. FreeToolsDaily processes PDFs with JavaScript running inside your browser, so the file never leaves your device. You can even disconnect from the internet after the page loads and the tool keeps working.

Is there a limit on how many PDFs I can merge?

You can add up to 50 files per merge, each up to 200 MB. For larger jobs, merge in batches and then merge the results.

Will merging reduce the quality of my PDF?

No. Pages are copied without re-encoding, so text and images look exactly as they did in the originals.

Can I merge PDFs on my phone?

Yes. The tool works in modern mobile browsers on Android and iPhone. Use the arrow buttons to reorder files on a touch screen.

Does FreeToolsDaily add a watermark?

Never. The merged file contains only your pages.
