Storage & Backups

Your screenshots remain in Owlbear storage. This version saves only names, tags, image URLs, and encounter lists in this browser. It does not sync your catalog to other devices.

↑ Import backup

Export a backup after you add or organize monsters. Import can also read the JSON backup from the earlier retrieval test. Import merges by image URL rather than duplicating cards. Removing a monster from this library never deletes its Owlbear image.

Add Screenshots to Owlbear

Step 1: Select screenshots on your computer and upload them into your Owlbear Notes collection.

Step 2: After the upload finishes, click Add monsters to select those screenshots once and register them in your library. Owlbear's API requires this separate selection step.
