Merge PDF Files

Combine multiple PDF documents into one file - processed locally in your browser

Combine two or more PDF files into a single document, in the order you choose. Useful for bundling invoices, reports, scans, or chapters into one file.

How it works

Select the PDF files you want to combine, then drag them into the order you need — the top file becomes the first section of the merged document. Click Merge and you get one PDF that contains every page of every file, in sequence.

Good to know

Page size can vary between files — merging a letter-size scan with an A4 report is fine; each page keeps its original size. Bookmarks and form fields from the source files are not carried over, but text, images, and links are preserved.

Worth knowing

  • Files are merged in the list order shown on screen — use the arrows or drag to rearrange before merging.
  • There is no page limit, but very large PDFs (hundreds of pages) take longer because everything is processed in memory.

Files are processed entirely in your browser — nothing is uploaded to a server.
