PDF · multiple files

Bring contracts, scans, invoices and reports together into a single PDF. Drop in as many files as you like, drag them into the right order, and PDF Converter stitches them together page-for-page without re-rendering anything, so text stays selectable and image quality is untouched.

How to merge PDF files

  1. Drop two or more PDF files into the box, or click to choose them.
  2. Drag the file cards (or use the arrows) to set the final order.
  3. Press Merge PDF and download the combined document.

Good to know

  • Pages are copied as-is: fonts, links inside pages, vector graphics and image quality are preserved.
  • Each source file can become a top-level bookmark so readers can jump between the original documents.
  • Password-protected files need unlocking first – use Unlock PDF if you know the password.

Frequently asked questions

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

There is no fixed file limit for merging. The practical limit is your device’s memory; a modern laptop comfortably handles several hundred megabytes.

Will merging reduce the quality of my PDF?

No. Pages are copied structurally rather than converted to images, so the merged file looks exactly like the originals.

Are my files uploaded to a server?

No. Merging runs entirely inside your browser tab, so the files never leave your device.
