Tips for Merging PDFs

  • Plan your order first. Think about the logical flow before uploading. It's easy to reorder, but starting organized saves time.
  • Check page orientations. If some PDFs are portrait and others landscape, they'll merge as-is. Consider rotating pages first if uniformity matters.
  • Use descriptive filenames. Name your merged PDF clearly (e.g., "Q4-2024-Financial-Reports") so you can find it later.
  • Preview before merging. Use the thumbnail previews to verify you have the right documents in the right order before combining.
  • Compress if needed. If the merged PDF is too large, consider compressing the source files first or using a PDF compressor afterward.
