How large can a file attachment be for a Secure Note?
File attachments are limited to 10 MB per item. While you can add multiple items to a Secure Note, we do not recommend going too far above the 10 MB threshold with multiple items attached to one note.
For attachment storage limits, free users can hold up to 50 MB of encrypted data. For Premium user, we offer up to 1 GB of encrypted data storage.
