Imgbb API
Overview
Imgbb is a free image hosting API that accepts an image via URL, base64 string, or multipart upload and returns a permanent hosted link along with thumbnail variants. No account is needed for basic use — just a free API key obtained instantly from the website. Developers commonly use it for user avatar uploads, automated screenshot hosting, or storing generated images without managing their own storage.
Beginner Tip
Get a free API key at api.imgbb.com with no credit card required. The simplest upload method is to base64-encode your image and send it as the "image" POST parameter — this avoids multipart encoding complications for beginners.
