Email PDF tips

📦

Most email providers cap attachments at 10–25 MB. Compress PDFs to under 5 MB to ensure reliable delivery.

⚡

A 20 MB PDF can take 30+ seconds to download on mobile. Compressing to 2 MB cuts that to 3 seconds.

🔒

Compression happens entirely in your browser. Sensitive documents never leave your device.

💡

Adjust the compression slider — start balanced and go smaller if the attachment still bounces.
