Tips for merging PDFs

• Put the files in the right order before merging — the tool keeps the exact sequence you set.
• Merging never reduces quality: text, images and formatting stay identical in the combined file.
• Need a smaller result? Run the merged file through Compress PDF afterwards.
• Only want certain pages? Use Split PDF or Extract Pages first, then merge.
