Does WhatsApp compress PDFs itself?

No — unlike photos, documents transfer as-is. Your 30MB PDF hits every recipient at 30MB unless you compress first.

What size works best for WhatsApp sharing?

Under 1–2MB sends and opens effortlessly on mobile connections; most documents compress there without visible loss.

Will the document stay readable on phone screens?

Yes — text is preserved sharply; phone rendering is exactly what the compressed file is optimized for.

Compress PDF for WhatsApp

WhatsApp carries documents everywhere now — but a 30MB PDF punishes the recipient\'s data plan and patience. Compress first and the document sends in seconds and opens on tap. We compress toward your target at the best quality that fits, never make the file larger than the original, and always show the real final size — very image-heavy files may land slightly above tight targets.

Phones are the destination

WhatsApp documents get opened on phone screens over mobile data — where a compressed PDF loads instantly and a bloated one stalls at 60%. Compression matches the file to how it will actually be consumed.

Group-chat mathematics

Send 25MB to a 50-member group and you have moved over a gigabyte of collective data for one document. The compressed version does the same job at a fraction — courtesy at scale.
