Frequently Asked Questions

Is it safe to upload my proprietary fonts here?▼
Absolutely. The entire process runs locally in your browser. Your font files are never sent to our or any third-party servers. Your intellectual property remains secure on your machine.
What font formats are supported?▼
Our tool supports the most common font formats used on the web and in design: TrueType (.ttf), OpenType (.otf), Web Open Font Format (.woff), and Web Open Font Format 2 (.woff2).
Why do some glyphs appear as blank squares?▼
A font file contains a map of characters (like 'A') to glyphs (the visual representation of 'A'). Some glyphs in a font file might not have a character code assigned to them (these are often used for ligatures or other substitutions) or might be control characters. These will appear as blank or placeholder squares in the character map.
Can I use this tool to identify a font from an image?▼
No, this is a font *viewer*, not a font *identifier*. You need to have the font file itself to upload and inspect it. Tools like "WhatTheFont" are designed for identifying fonts from images.
