The maker has restricted this font. Do not convert it or put it on a website unless you have permission.
A font's licence decides how it may be used and converted. Read it first. Converting keeps the embedding setting as it is. This tool cannot remove any limit.

About the font viewer
You have a font file and want to see what it looks like. Normally you must install it first. Here you just open the file. You see your own words in that font, every glyph inside it, its name and its licence.
It works with TTF, OTF, WOFF and WOFF2 files. Your browser reads the file, and it is never uploaded. You can open several fonts and compare them in one list.
Features
- Your own text — type anything and change the size, weight, line height and colour
- Dark background — see how the font looks as light text on a dark page
- All sizes — the same line from 12 to 96 pixels, one under the other
- Glyph list — every glyph in pages, so even a font of 65,000 glyphs stays fast
- Glyph facts — click a glyph for its code point, name and width, and copy the character
- Font details — family, style, version, designer, licence, metrics, weights and OpenType features
- Compare fonts — all open fonts in one list, showing your text in each one
- Convert — TTF and OTF to WOFF2 and WOFF, WOFF and WOFF2 back to TTF or OTF, plus a CSS snippet
How to use it
- Drop one or more font files on the box, or press Choose font files
- Type your text and move the sliders on the Preview tab
- Click another font in Your fonts to compare them
- Open Glyphs and click a glyph to see its code point and name
- Open Details to read the family, designer and licence
- Open Convert, read the licence, and press the download button you need
Which format should I use?
| Format | What it is | Best for |
|---|---|---|
| TTF | Common desktop font | Installing on a computer |
| OTF | Desktop font, often with more features | Design programs |
| WOFF | Packed font for the web | Very old browsers |
| WOFF2 | Smallest font for the web | Websites today |
All current browsers can use WOFF2, and it is often about half the size of the TTF. For most websites, WOFF2 alone is enough.
Converting does not change how the letters look. Only the packing changes.
What the OpenType feature codes mean
The Details tab lists short codes for the extra skills of a font. These are the ones you will see most:
| Code | Meaning |
|---|---|
| kern | Better spacing between letter pairs |
| liga | Joined letters, like fi |
| smcp | Small capitals |
| onum | Old-style numbers |
| tnum | Numbers of equal width, for tables |
| ss01 | A set of other letter shapes |
Not every font has these. A list with few codes does not mean a bad font.
Font licences: read this before you convert
A font's licence decides how it may be used and converted. Some licences allow almost everything. Others do not allow web use or a change of format, even for a font that you paid for or that came with your computer.
The Convert tab shows the licence text from inside the file, if the maker put one there. It also shows the font's embedding setting, a small note from the maker about embedding the font in other files.
This tool never changes that setting and cannot remove any limit. If the maker has restricted a font, you see a warning. If there is no licence text, ask the maker or check where you got the font.
Frequently asked questions
Is my font uploaded?
No. Your browser reads the file on your device. The page only downloads two free helper programs (opentype.js and wawoff2), and your font is not sent anywhere.
Can I install a font with this tool?
No. A web page cannot install fonts. To install one, open the file with your computer's own font tool. You can use this page to look at it first.
Why does the WOFF2 button take so long on a big font?
WOFF2 uses very strong packing. A normal font takes a few seconds. A Chinese, Japanese or Korean font can take a minute or more, so it has its own Make WOFF2 button. You can keep using the page while it works.
Can I open a TTC file?
Yes. A TTC file is a collection: several fonts in one file. Many of the Windows fonts for Chinese and Japanese are TTC files. This tool opens each font in the collection as its own row, and you can save any of them as a TTF, OTF, WOFF or WOFF2 file.
Why does bold look wrong?
A normal font file holds one weight. When you ask for more, the browser only makes the letters thicker. A variable font holds all its weights, so its slider gives you real ones.
Why do some glyphs have no code point?
Fonts hold extra shapes, like small capitals and joined letters. You do not type these directly. The font swaps them in by itself, so they show a number in the list, not a code.
Good to know
- Files up to 150 MB can be opened, but a very large font needs a lot of memory
- The glyph pictures show the default weight, even in a variable font
- WOFF metadata and private data blocks are not kept when you convert
- Colour emoji show as plain outlines in the glyph list
- Without internet the preview still works, but the details and WOFF2 need their helper programs
