About quality

  • This tool merges PDFs without intentionally compressing them. Pages are copied directly, so text, images, fonts and vector graphics are not re-rendered or converted to images.
  • Page sizes and orientations are kept as they are in each original file.
  • Some advanced PDF features, such as digital signatures, interactive form fields and certain annotations, may not be preserved perfectly after merging.
  • Password-protected PDFs are not supported. Remove the password first.
