reverse-image
IQDB
A combined reverse-image search across the major booru image boards. Danbooru, Gelbooru, Zerochan and others, covering tens of millions of tagged anime-style images. You give it an image or URL and it checks all the services at once; output is plain HTML with no API. The quickest way to find the catalogued, tagged source of an anime image when SauceNAO leaves doubt.

Por que é útil e como funciona
IQDB is purpose-built for the anime and manga booru ecosystem: it searches Danbooru, Gelbooru, Zerochan, Konachan, Sankaku Channel, and several other tagged image boards in a single query, returning the closest matching post from each. It is most useful when SauceNAO does not return a confident result for an anime-style image, since IQDB's fuzzy visual matching can find a source even from a cropped or slightly edited version. Echo passes your image URL directly to IQDB and links you through to review the HTML results page.
O que há dentro
