How to Merge PDF Files Safely

Whether you are combining legal documents, consolidating invoices for your accountant, or putting together a massive research portfolio, you need a PDF merger that is both fast and completely secure.

Why is our PDF Merger different?

Most free PDF tools online operate by forcing you to upload your highly sensitive documents to their servers. They process the files on their end, and send you a download link. This is a massive privacy risk for financial records, NDAs, and personal identification.

Angtool handles 100% of the PDF manipulation locally. When you drag and drop your PDFs into our tool, your browser's own memory is used to parse the code, extract the pages, and stitch them together into a new file.

  • Zero Uploads: Disconnect your internet after loading the page, and the tool will still work perfectly.
  • No File Size Limits: Because we don't have to pay for server bandwidth, you can merge massive files instantly.
  • No Watermarks: The output file is completely clean. We do not brand your documents.

Instructions

  1. Drag and drop two or more PDF files into the upload box above.
  2. Use the up and down arrows to rearrange the order of the documents. The top document will be the first pages of the new PDF.
  3. Click the Merge PDFs button.
  4. Your browser will instantly generate and download the combined file.
