FAQ
How many types are supported?+
100+ common extensions. Images, video, audio, documents, code, and archives.
What is a MIME type?+
Multipurpose Internet Mail Extensions — a standard identifier for file format (e.g., image/png, application/json). Used in HTTP and email standards.
Why does correct MIME matter?+
Wrong MIME can cause (1) browsers to mishandle files, (2) security bypass risks, (3) broken downloads or display.
How do I detect spoofed extensions?+
Don't trust the extension — also check the magic number (first bytes). Use the file-type library.
Custom format MIME types?+
If non-standard, use application/x-yourname. Standard formats are preferred for compatibility.
