Zendesk attachment limits
- Ticket comments, web form and customer portal: 50 MB per file.
- Email: oversized attachments are replaced by links in notifications, which recipients often can’t open.
- Zendesk says the limit cannot be increased for an account.
For agents and for customers
Agents: ask customers to send a short screen recording and point them to this page — compression happens on their device, so nothing confidential passes through a third-party service. Customers: compress the recording here, then attach it to the ticket or the request form.
Keep it readable
- Keep Resolution: Original for screen recordings so small text stays sharp; 50 MB is enough for 10+ minutes of screen.
- Untick “Keep sound” if nobody is talking — it saves space.
