image/png
The MIME type for PNG images — the W3C's standard lossless raster format and the default choice for logos, screenshots, and UI assets on the web.
Typical extensions
Primary uses
- Serving images on the web
- Referenced by `<img>` and `<picture>` tags in HTML
- Screenshots shared between applications
In a browser
All browsers render PNG per spec. Also works inline as `data:image/png;base64,...`.
On a server
Combine `Content-Type: image/png` with a long `Cache-Control` for efficient CDN delivery.
In email
Embeds cleanly as an inline image in HTML email; very large files fall back to an attachment.
