How to open .SJPG files on Linux
To open .SJPG files on Linux, check whether your desktop environment recognizes the MIME type image/vnd.sealedmedia.softseal.jpg; recognition alone may not include a working viewer without an Unsealer client.
Step-by-step instructions
- Check whether your desktop environment recognizes the MIME type image/vnd.sealedmedia.softseal.jpg; recognition alone may not include a working viewer without an Unsealer client.
- If your organization provides a supported Unsealer/IRM solution for Linux, install it and open the file with that application.
- If no Linux client is available, move the file to a supported desktop system with the Unsealer/IRM client.
Common issues
The file opens as gibberish or no image preview appears
.SJPG is a sealed/protected variant of JPEG (image/vnd.sealedmedia.softseal.jpg). Standard photo viewers typically cannot decode it, so thumbnails and previews often fail.
- Open the file using the Sealed Media “Unsealer” / Oracle IRM Desktop client instead of a regular image viewer.
- If you received the file by email or a download portal, re-download it to ensure it was not altered in transit.
‘Access denied’ / cannot unseal the file
Sealed files commonly require authorization (policies/rights). Without the correct account, credentials, or rights, the Unsealer/IRM client may refuse to open it.
- Confirm you are signed in with the correct organization account in the Unsealer/IRM client.
- Ask the sender or your administrator to verify you have permission to access the sealed content.
Renaming .SJPG to .JPG doesn’t work
Changing the extension does not remove the sealing/protection, so most JPEG tools will still fail to open it.
- Restore the original .sjpg extension if you changed it.
- Use the Unsealer/IRM client to open (or export/decrypt, if your permissions allow) a standard .jpg copy.
No application is associated with .SJPG
Your system may not have an Unsealer/IRM client installed or configured to handle the SealedMedia MIME type.
- Install the organization-approved Unsealer/IRM Desktop software and try again.
- On Linux desktops, ensure the MIME database/associations include image/vnd.sealedmedia.softseal.jpg and point to the correct application (where applicable).

Recover a deleted or lost .SJPG file
If the file was deleted by mistake or the drive was formatted, data recovery software may be able to get it back. Stop writing to that drive right away, because new data can overwrite what you want to recover.

Security note
.SJPG files are designed to enforce access control; if you obtain an .SJPG outside official channels, treat it as potentially sensitive protected content and avoid trying to bypass protection.
