How it's rendered
opentype.js + the browser's FontFace API. Reads font metadata with opentype.js, and registers the file with the browser's FontFace API for accurate native text rendering.
Nothing about this file is ever sent to a server — open your browser's DevTools Network tab while using this viewer and you'll see no request carrying your file's contents.
100% Private
Files never leave your device. There is no server that ever receives your file's contents.
No Uploads
Every format is decoded and rendered locally via WebAssembly or JavaScript. Open your browser's Network tab and confirm nothing is sent.
No Storage
Nothing is written to a server or database. Memory clears the moment you close or reload the tab.
GDPR-friendly by design
There's no file data collection to comply with in the first place — no account, no tracking of file contents, no analytics on what you view.
Font viewer — FAQ
Which font formats are supported?
TrueType (.ttf), OpenType (.otf), and Web Open Font Format (.woff, .woff2).
Do I need to install the font to preview it?

Can I see all the characters in the font?
Yes, a character set grid shows the font's available glyphs.
Is the font file uploaded anywhere?
No, it's read and rendered entirely client-side.
Can I type my own sample text?
Yes, the sample text field is fully editable.
