Compress a PDF to Send on WhatsApp
WhatsApp lets you send documents up to 100 MB, but a smaller PDF sends faster, uses less of the recipient's data, and dodges failures on slow connections. Compress it first — all in your browser, so the document stays private.
The requirement
- WhatsApp document limit
- 100 MB
- Practical target
- 1 MB or less (fast send)
- Best for
- Scanned notes, forms, brochures
- Format
These are typical published values and can change from year to year and from one portal to another. Always confirm the exact requirement in the official notification or upload portal before you submit — the official source takes precedence over anything here.
