Imgbb API

⭐ Beginner's Pick Cloud Storage & File Sharing / API Key Intermediate HTTPS
Varies by plan (check documentation)

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.

Common Errors & Troubleshooting

400 Invalid image format The image parameter contains malformed base64 or a URL that Imgbb cannot fetch
Strip the data URI prefix (data:image/png;base64,) from base64 strings before sending; only the raw base64 data is accepted
100 Bad Request — API key missing The key query parameter was not included in the request URL
Append ?key=YOUR_API_KEY to the endpoint URL: https://api.imgbb.com/1/upload?key=YOUR_API_KEY
Image over 32 MB rejected Imgbb enforces a 32 MB per image size limit
Resize or compress the image before uploading using a library like sharp (Node.js) or Pillow (Python)
