What is the MIME type of .tif files?
The MIME type (media type) for TIFF image files with the .tif extension is image/tiff. Common in print and scanning; most browsers (except Safari) cannot display TIFF.
Content-Type header
Content-Type: image/tiff
Server configuration
| Server | Configuration |
|---|---|
Nginx (mime.types or types {}) | image/tiff tif; |
Apache (.htaccess) | AddType image/tiff .tif |
IIS (web.config) | <mimeMap fileExtension=".tif" mimeType="image/tiff" /> |
| Node.js / Express | res.type('tif') or res.setHeader('Content-Type', 'image/tiff') |
| Amazon S3 | Set Content-Type: image/tiff on the object (metadata), or pass --content-type image/tiff to aws s3 cp |
Should .tif files be compressed?
No. TIFF image files are already compressed internally, so gzip or Brotli would waste CPU and barely reduce — sometimes even increase — the size. Leave image/tiff out of your compression configuration.
Why the MIME type matters
Browsers decide what to do with a response — render, run, play or download — from the Content-Type header, not the file extension. With X-Content-Type-Options: nosniff, a wrong type causes stylesheets and scripts to be blocked outright. For uploads, never trust the type sent by the client; check the file’s content (its magic bytes) on the server.
