How to Send PDF on WhatsApp — Compress to Under 100MB

3 min read · May 21, 2026

WhatsApp allows file sharing up to 100MB — but most large PDFs like brochures, books, or scanned documents are much bigger. The solution: compress your PDF to under 100MB (or ideally under 10MB for fast delivery) before sending.

Tips

  • For sending a brochure or presentation, 2–5MB is usually fine — most people read on mobile
  • If the PDF has mostly text, it will compress very well (80–90% reduction)
  • Scanned documents compress the most — try "Low" quality first
  • You can also use WhatsApp's "Document" option instead of "Gallery" — it keeps the PDF format
