Wait, WhatsApp Has a PDF Size Limit?

Yep. Here's the thing nobody tells you until you're staring at that error message:

WhatsApp Document Limits:

100MB — maximum file size
~16MB — practical limit (depends on network)
2MB or less — what actually works every time

That 100MB limit sounds generous, but in reality? Larger files fail constantly. Sometimes they're "sending" for 20 minutes before giving up. The sweet spot is under 2MB — small enough to send instantly, even on a slow connection.

Why Is Your PDF So Big Anyway?

Your PDF isn't just text. It's probably packing:

📷High-res images — that scanned receipt? 3MB just for one page.
🔤Embedded fonts — every font style adds weight.
🗂️Multiple pages — more pages = more everything.
✏️Editing history — some PDFs carry invisible baggage from edits.

Quick Tips for Even Smaller Files

💡 Compress images before adding to PDF

If you're creating the PDF yourself, shrink the images first. Use our Image Compressor.

💡 Split multi-page PDFs

Sending a 20-page document? Split it into chunks. Our PDF Splitter can help.

💡 Skip the fancy formatting

Gradients, drop shadows, and decorative fonts add file size. Keep it simple if size matters.

Still Too Big? Try These

If compression isn't cutting it, you've got options:

Send as a link: Upload to Google Drive, share the link via WhatsApp
Remove pages: Only send what's actually needed
Convert to images: Sometimes JPGs are smaller than PDF pages
