image/jpeg
The MIME type for JPEG images — the most common photo format on the web.
Typical extensions
Primary uses
- Photographic content on web pages
- Inline images in HTML email
- Social media uploads
In a browser
Every browser renders inline. Progressive JPEGs paint from blurry to sharp while loading.
On a server
Long `Cache-Control: public, max-age=31536000` is standard. CDNs commonly re-serve WebP/AVIF based on `Accept`.
In email
Inline support is universal. EXIF data (including GPS) travels with the file — strip before sending if privacy matters.
