Default handling

Handling verdict
The originating application is the safest default; browser support is not assumed.
Use a format-aware application rather than a plain-text editor.
HTTP content encoding can usually reduce this format further.
Audit licensing before embedding in commercial projects.
HTTP response headers
Content-Type: font/ttf
Content-Disposition: attachment; filename="example.ttf"
X-Content-Type-Options: nosniffThe MIME type describes the payload, Content-Disposition controls whether the browser previews or saves it, and nosniff prevents the browser from silently substituting a guessed type.
HTML file input
accept=".ttf,font/ttf"Use this value on <input type="file"> to steer the picker toward .ttf, its known aliases, and files reporting font/ttf. It improves selection, but it is not validation—check the bytes again after upload.

How to work with .ttf
operational notesOpen it with the format-aware tool first
Start with Font Book, Adobe Fonts, Design tooling. Self-host with proper `font-face` declarations and include fallbacks for accessibility. If the file came from someone else, keep the original untouched and work on a copy so a failed conversion cannot destroy the only source.
Safety note
Audit licensing before embedding in commercial projects.
