How it works

  1. Choose PDFs and images: Drag files into the tool or use the file picker. DropIn PDF checks the file type and keeps processing on your device.
  2. Arrange or choose options: Reorder pages or files, choose the output format, and set page options when the tool supports them.
  3. Download one PDF: Create the result and download it without a watermark, account signup, or server upload step.
