About Merge PDF

Merge PDF is a free online tool from Supreme Pro. Combine several PDF files into one document. It runs in your browser, so there is nothing to install and no account to create. PDF work is one of the most common reasons people look for an online tool, and because this one runs locally your documents are never uploaded.

Common uses

  • Prepare documents for email, printing or upload to an online portal
  • Fix a file that is too big, in the wrong order or rotated
  • Combine and tidy PDFs without installing desktop software

Tips for best results

  • Keep a copy of the original file before you download the result
  • Very large files can be slow on older phones, so close other tabs first
  • Open the finished PDF and check it before you send it on

Practical tips

Put the files in their final order before merging, because changing it afterwards means starting again. If the merged file is too large for an upload limit, run it through the PDF Compress tool next. Keep your originals until you have checked the result.
