Compress PDF for WhatsApp — Shrink PDFs Under the 16MB Sharing Limit
WhatsApp caps document shares at 16MB — and phone-scanned PDFs sail right past it. Drop in your PDF and this tool recompresses its embedded images pass by pass, lowering quality only as far as needed to fit (or get close to) 16MB, so it sends cleanly in any chat and opens fast on phones. Your document never leaves your browser.

2 Compression approach

✅ Done — your WhatsApp-ready PDF
How it works
- Step 1 — Drop in one PDF (phone scans, reports, e-books — anything you want to share).
- Step 2 — Pick an approach preset: balanced, max quality, or aggressive.
- Step 3 — The tool decodes every embedded image, re-encodes it as JPEG at descending quality levels, rebuilds the PDF, and stops the moment the file fits under 16MB. Text and vector content is preserved losslessly.
Everyday uses
- Everyone — send scanned documents in WhatsApp chats without the “file too large” error.
- Students — share class notes and scanned textbooks in study groups.
- Freelancers — deliver invoices and contracts straight to a client’s WhatsApp.
- Families — share photo-heavy PDFs (recipes, manuals, kids’ schoolwork) that open fast on phones.
Rule of thumb: most PDFs are already under 16MB — the tool tells you instantly and rebuilds the file cleanly anyway. Phone scans are the usual culprits; the balanced preset handles them without visible quality loss.
