How to Compress a PDF for Email & WhatsApp

Email providers and WhatsApp reject files that are too large — Gmail caps attachments at 25 MB and WhatsApp at 100 MB, and smaller files simply send faster. PdfWord's free Compress PDF tool shrinks your PDF right in your browser, so the original never leaves your device. No signup, no limits, no watermark.

Steps

  1. Open the Compress PDF tool — Go to the Compress PDF page and upload your large PDF file.
  2. Click “Compress PDF” — The file is rebuilt to remove wasted space — entirely on your device, in seconds.
  3. Check old vs. new size — You'll see the original and compressed sizes instantly, so you know exactly how much was saved.
  4. Download and share — Save the smaller PDF and attach it to your email or send it on WhatsApp.
