Why compress PDF for WhatsApp?
WhatsApp has become a primary way to share documents in many parts of the world — invoices, receipts, contracts, homework, ID copies. While WhatsApp's 100MB limit is generous, large files take forever to upload on mobile data and eat through recipients' storage. Compressing your PDF before sharing makes the experience faster for everyone. AskPDF works directly in your phone's browser, so you can compress and share without downloading any app.
