FileHint

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.
