Skip to contentMIME types (media types) label file formats for HTTP — application/pdf, image/png, application/json.
Browsers and APIs use MIME types in Content-Type headers to decide how to render or parse bytes. Wrong MIME types break downloads, CORS preflight and email attachments.
Common web types include text/html, application/javascript and multipart/form-data. Tentaco MIME lookup and file sniff utilities help debug upload issues locally before you fix server configs.
