Tens of thousands of saved images become useless the moment you cannot find the one you want, and Blombooru turns that private pile into a searchable, tag-organized library on your own server. Its Danbooru-style tagging uses familiar categories like artist, character, and copyright, with tag-based search and negative exclusion to slice a huge collection down to exactly the post you remembered. A dedicated tag gallery lets you browse and manage the vocabulary itself, and CSV imports bring existing tag lists in through the admin panel. Albums organize media with nested sub-albums and manual sorting, while parent-child relationships and a TF-IDF similarity engine surface variations, multi-page comics, and near-duplicates. Getting media in is flexible: upload files, compressed archives, filesystem scans, or paste a Danbooru or Gelbooru post URL and let it fetch media, tags, rating, and source automatically. AI-generated images keep their SwarmUI, ComfyUI, A1111, or NovelAI metadata viewable, optional WDv3 or PixAI auto-taggers suggest tags with one click, and tag implications and aliases keep everything consistent. Secure mode, share links, thumbnail blurring, scoped API keys, and custom themes from the admin panel finish the picture.
