How to send a presentation without an attachment
Mail servers cap attachments around 20 to 25 MB, PDFs strip the animation, and a .key file needs Keynote on the other end. Send a link and all three problems go away.
Why the attachment fails
A deck with video is bigger than most mail systems allow. Compressing it to a PDF loses builds, transitions and audio. Sending the original .key only works if the recipient has Keynote, which on Android or Windows they do not.
Send a link instead
The link route takes a few minutes the first time and under a minute after that.
- Keynote for Mac: File → Export To → HTML… and save.
- Right-click the export folder → Compress.
- Upload the .zip on linkdeck.me and paste the link into your email or message.
Size limits
Free decks can be up to 200 MB. Pro decks up to 500 MB. Both are far beyond an email attachment, and the recipient's mailbox stays empty because nothing is attached.
Any device, no software
The link opens in a browser on iPhone, Android, Mac and Windows. On a phone it runs landscape with tap to advance; video plays inside the slide and audio starts on the first tap.
Replace, do not resend
On Pro you can upload a new version in place. The link you already sent plays the new deck, so a correction never needs a second email.
Keynote only, and what that means
Linkdeck hosts Keynote's HTML export. If your deck is in PowerPoint or Google Slides, this route does not apply; there is no conversion.
Questions
What is the maximum size?
200 MB per deck on Free, 500 MB per deck on Pro.
Does the recipient need to sign in?
No. They tap the link and the deck opens. If you turn on the email gate (Pro), they enter an address first; there is still no account to create.
Can I see whether they opened it?
On Pro you get views, time per slide, countries and devices, and with the email gate on, the addresses of people who opened the deck.
Send your next deck as a link
Upload a Keynote export free and paste the link where the attachment would have gone.
