Frequently Asked Questions
Q: Why is Subsetter not accepting my font?
Make sure that you upload a FontFont with the file extension .ttf, .eot or .woff. Subsetter supports TrueType-flavoured Offc FontFonts and Web FontFonts in WOFF or EOT format.
topQ: Does Subsetter only works with Web FontFonts?
No, you can also subset your TrueType-flavoured Offc FontFonts (.ttf) in order to comply with § 2.2. Embedding in our EULA.
topQ: Why does Subsetter not always offer me all subsetting options?
Subsetter examines which features (i.e., kerning, hinting, figure sets and languages) your uploaded font contains and offers only the applicable options.
topQ: Why is there no option to change the number style?
Some fonts do not offer different number styles. You can check whether your font contains Oldstyle Figures (OSF) at FontFont.com.
topQ: How do I know what characters I need?
You should activate all languages that you wish to support. If you’re not sure, you can uncheck all language options and enter the desired text in the text box above the glyph table.
topQ: I disabled some languages. How can I reactivate individual characters?
Enter the desired characters in the text box above the glyph table.
topQ: Can I subset multiple fonts at once?
No, but Subsetter saves your current settings and applies them to the next font that you upload.
topQ: I chose Oldstyle Figures (OSF), but Tabular Figures (TF) are still shown in the glyph table. What happened?
The characters displayed in the glyph table depend on your system font. Some system fonts do not offer different number styles. This does not mean that your changes were not accepted.
topQ: Do I need to refresh the statistics under “Resulting Font” before downloading the optimized font file?
No. The optimized font file is generated according to your current settings.
topQ: The statistics under “Resulting font” do not change, even though I selected OSF. Does that mean that the file size has not been reduced?
Yes, that’s right.
topQ: I’m not sure if I need kerning. What do you recommend?
Most browsers do not support kerning, therefore we suggest further reducing the file size of your Web FontFont by removing the kerning information.
topQ: I’m not sure if I need screen optimization. What do you recommend?
If you want to use the font in other systems besides Mac OS or iOS, leave the option turned on.
topQ: I disabled almost everything, but certain characters remain in the glyph table. Why?
Some characters are used by certain systems to automatically optimize the screen display. Therefore, approximately 30 characters will always remain in the file to ensure that the font works properly. These characters cannot be removed by Subsetter.
topQ: Why do some of the cells in the glyph table appear empty?
The character is either not included in your uploaded font file or it is too small to be visible. Place the mouse over the cell in order to get more information (Unicode value) about the character in question.
topQ: I subsetted and downloaded a font, but now I need some more characters. What can I do?
You will need to upload the complete original font file once again and repeat the subsetting process.
topQ: The language I need is not listed. What should I do?
You can enter the characters needed in the text box above the glyph table. If you’re not sure, either insert the full text or find out which characters your desired language needs. (e.g. Eesti Keele Instituuti or Evertype).
topQ: Why can’t I see certain characters in the glyph table?
The uploaded font file does not contain these characters.
topQ: How can I enter special characters not accessible via my keyboard into the text box without the use of Unicode?
First select the desired special characters from the glyph table with your mouse, and then copy and paste your selection into the text box. Alternatively, you can drag and drop your selection into the text box.
