File attachments are available for Premium users and members of paid organizations. These users paid have 1GB of encrypted storage for file attachments. More storage can be purchased in 1GB increments.
Files can be attached to vault items from any Bitwarden app. An individual file attachment must be 500 MB (100 MB if uploading from mobile) or smaller. Attachments are encrypted and decrypted locally, meaning no unencrypted attachment data is transported over the internet or stored by the server.
note
Attachments on individual vault items and all Sends use the individual storage space granted by premium subscriptions or organizations. Attachments on organization owned items use shared organizational storage space. Learn how to add storage space.

Add storage space
Paid users and members of paid organizations have 1GB of encrypted storage for file attachments. Individuals and organizations can purchase additional storage space by completing the following steps:
note
Adding storage space will adjust your billing totals and immediately charge your payment method. The first charge will be prorated for the remainder of the current billing cycle.
To add storage space in your individual vault:
In the Bitwarden web app, navigate to Settings → Subscription.
In the Storage section, select the Add Storage button:
Add storage to individual vault
Using the counter, choose the number of GB of Storage to Add and select Submit.
To add storage space in your organization vault:
In the Bitwarden web app, Open the Admin Console using the product switcher:
Product switcher
From the navigation, select Billing → Subscription.
In the Manage subscription section, select the Add Storage button:
Add storage to organization vault
Using the counter, choose the number of GB of Storage to Add and select Submit.
While attachment storage is still tied to being a paid user or member of an organization when self-hosted, the amount of storage space is only limited by how much space is available on the volume that contains your attachments directory, with an upward limit of 10 TB (10240 GB). Users and admins do not need to change any values to increase that limit.
Fixing old attachments
Prior to December 2018, file attachments used a different method of encrypting their data. We have since moved to a newer, better way of encrypting attachments. Any attachments that use the older encryption method will be labeled with an alert icon in your vault listing. You should upgrade these old attachments to the newer method of encryption so that other account-related features can function properly:
Open the page for editing your attachments.
Click the Fix button next to the old attachment. This process will download the attachment, re-encrypt it using the new encryption method, re-upload the attachment back to your vault, and delete the old version of the attachment.
Once an attachment has successfully been upgraded, the alert icon and fix button should disappear.
