Jira attachment size limit: Cloud and Data Center
Updated
Jira Cloud accepts files up to 1 GB each by default, and an admin can raise that to 2 GB. Jira Data Center and Server default to only 10 MB per file, with the same 2 GB maximum. The limit is per file, and only someone with Jira admin rights can change it.
Jira Cloud
- Default: 1 GB per file.
- Maximum an admin can set: 2 GB per file.
- Who can change it: users with the Administer Jira global permission.
- Where: Settings → System → Advanced → Attachments → Edit Settings.
If a file well under 1 GB is refused on Cloud, the admin has probably lowered the limit. Your plan’s total file storage can also run out, which stops new attachments whatever their size.
Jira Data Center and Server
- Default: 10 MB per file (10,485,760 bytes). This catches many people out: a phone video or a log bundle is often bigger.
- Maximum: 2 GB per file (2,147,483,647 bytes).
- Where: Administration → System → Advanced → Attachments → Edit Settings, then the Attachment size field.
Raised the limit and uploads still fail?
Something in front of Jira has its own, lower limit. Atlassian documents the case of Microsoft IIS, where the maxAllowedContentLength setting in web.config must be at least the Jira limit. Reverse proxies and load balancers have equivalent request-size settings, such as nginx’s client_max_body_size, so check every layer between the browser and Jira.
When your file is bigger than the limit
- Ask your Jira admin whether the limit can go up. On Cloud there’s room up to 2 GB; on Data Center the 10 MB default is often just never changed.
- Reduce it. Trim a screen recording, zip log files, or export a PDF at reduced size. How to compress files for sharing covers each file type.
- Link to approved storage. Upload to your company’s file storage and paste the link into the work item, so access stays under your organisation’s control.
For a non-confidential file going to someone who isn’t in your Jira, such as a customer sending you a screen recording, a short-lived code can be simpler: ShareQuik takes up to 500 MB and gives an 8-character code. Don’t paste such a code into a work item many people can see, because anyone with the code can download the files until the share expires.

Frequently asked questions
What is the maximum attachment size in Jira?
Up to 2 GB per file on both Jira Cloud and Data Center. The default is 1 GB on Cloud and 10 MB on Data Center.
How do I increase the Jira attachment limit?
A Jira admin changes it under Advanced → Attachments in the system settings. Regular users can’t change it.
Is the Jira limit per file or per work item?
The size limit applies to each file you attach.
Why does Jira reject a file under the limit?
On Data Center, a web server or proxy in front of Jira may allow less than Jira does. On Cloud, check whether the admin lowered the limit or your site has run out of file storage.
Need to send a file from outside Jira?
For non-confidential files up to 500 MB, upload once and share an 8-character code.
