How to Compress a PDF to Send on WhatsApp (Free)
WhatsApp limits PDF file sharing to 100 MB, but large PDFs can be slow to send and receive. Compress yours for instant sharing — free, no app needed.
WhatsApp allows PDF sharing up to 100 MB, but large files are slow to send on mobile data and take up storage on the recipient's device. Compress your PDF first on your phone's browser for faster, lighter sharing.
WhatsApp PDF Limits
WhatsApp allows document files up to 100 MB. For practical sharing, under 10 MB is ideal — it sends and downloads quickly on mobile data and does not fill storage.
