Merge PDF files

A PDF merger combines several documents — contracts, scans, invoices, chapters — into a single file that's easier to send and archive. This tool does it entirely in your browser with pdf-lib: add your PDFs (and images, which each become a page), drag them into the order you want, and download one combined document. Because nothing is uploaded, sensitive paperwork never leaves your device, and there's no sign-up or watermark.

1. Add your files

   Drop PDFs (and images) in any order.

2. Reorder

   Move files up or down to set the page order.

3. Merge & download

   Get one combined PDF in a click.

• Files stay on your device

  Merging runs locally — ideal for contracts, IDs and anything confidential.

• Images become pages

  Drop JPG, PNG or WebP alongside PDFs and each image is added as a page.

• Drag to reorder

  Set the exact page order before you merge.

• Free, no watermark

  No account, no limit, and a clean output PDF.

• Split PDF

  Do the opposite — pull pages or ranges out of a PDF.

• Image compressor

  Shrink images before adding them as PDF pages.

• Image converter

  Convert images to the format you need first.
