How to send large files without email attachments
Your file is ready, you hit send, and it bounces. Here's why that happens and the easiest way around it.
Why big attachments get rejected
Most email services cap attachments at around 20–25 MB. Gmail and Yahoo allow 25 MB, Outlook around 20 MB, and many company mail servers set the limit even lower.
Attachments also grow by about a third when they're sent, so a file that looks like 20 MB on your computer can already be over the limit.
Why zipping rarely helps
PDFs, slides and images are already compressed. Zipping them usually saves very little, and some company inboxes block zip files outright.
The easier way: send a link
Instead of attaching the file, upload it once and send a link. The email stays small, nothing bounces, and the recipient opens the file right in their browser.
- Upload your PDF, PowerPoint or Word file (up to 200 MB)
- Copy the link DeckDrop gives you
- Paste it into your email, chat or LinkedIn message
Bonus: know when they read it
Because the file is opened through a link, DeckDrop can show you when it was viewed, how long people spent, and — for PDFs — which pages they read. You'll know exactly when to follow up.
