Serve .ogg files with the right type
The response header to send:
Content-Type: audio/ogg
Most servers pick the type from the file extension. If yours sends the wrong one, map it explicitly:
nginx (inside the types block in mime.types)
audio/ogg ogg oga;
Apache (.htaccess or server config)
AddType audio/ogg .ogg .oga
Express
res.set("Content-Type", "audio/ogg");Python
import mimetypes
mimetypes.add_type("audio/ogg", ".ogg")
mimetypes.add_type("audio/ogg", ".oga")HTML file input
<input type="file" accept=".ogg,.oga,audio/ogg">
Check it
See what a server sends for a file, and what type a local file really is by its contents:
curl -sI https://example.com/file.ogg | grep -i '^content-type:' file --mime-type file.ogg
Frequently asked questions
What is the MIME type for .ogg files?
audio/ogg. You may also see application/ogg, but audio/ogg is the one to send. The same type covers .oga.
What Content-Type header should a .ogg file be served with?
Content-Type: audio/ogg. It's already compressed, so servers shouldn't gzip it.
How can I tell if a file is really a .ogg?
Check its bytes rather than the extension: OGG files start with 4F 67 67 53 (OggS). On the command line, file --mime-type name.ogg does this for you.
