When should you compress a PDF?

  • When a website or online form rejects your PDF because the file size is too large.
  • Before emailing a CV, portfolio or project report so it loads quickly for the recipient.
  • To save space on cloud storage or shared drives that have limited capacity.
  • When you work with scanned documents that contain high-resolution images and take long to upload.

Which compression mode should you choose?

  • Balanced: Recommended for most documents. Gives a smaller size while keeping pages readable.
  • Strong: Best when file size is more important than visual quality, for example for archiving or quick uploads.
  • Preserve: Use this mode for PDFs that must stay very sharp, such as brochures, certificates or design work.
