Why compress a PDF before sending on WhatsApp?
Smaller PDF files are easier to send through chats and easier for the receiver to download. This matters especially when someone is using mobile data, has limited phone storage, or needs to open the document quickly.

How to send a PDF on WhatsApp
- Open WhatsApp on your phone or computer.
- Open the chat where you want to send the file.
- Tap the attachment icon and select Document.
- Choose your PDF file.
- Send the file.
Sending it as a Document keeps the PDF intact; the receiver can open, save, or forward it like any other file.
What if the file is still too large?
If the compressed file is still too large, try splitting the PDF and sending only the needed pages. You can also remove extra pages before compressing again.
Compress scanned PDFs for WhatsApp
Scanned PDFs are often large because each page is stored like an image. If your PDF was created from phone photos or scans, compressing it can make a big difference. If you have a set of photos rather than a PDF, convert them to one PDF first, then compress it before sending.
