Karetkar is a simple, open-source web application that enables you to build bitmap fonts from custom glyph sets. The application has been developed in React and Typescript and you can use it to design fronts for specific use cases without the requirement of building all possible glyphs.

All that you need to do is navigate to the web application and use the various tools that have been provided for use.

What is a Bitmap Font

A Bitmap Font is a digital file that contains a set of glyphs (characters) that are graphically related to each other. When enlarged, the edges of a bitmap font get jagged unlike a scalable font which looks the same no matter how much you enlarge it. This is due to the fact that a bitmap font is comprised of several pixels that make up a single glyph which causes quality degradation when you zoom in.

Once you have built the required glyphs, you can export the font to an OTF file (OpenType format). This font format is a registered trademark of Microsoft Corporation. It is scalable but retains the TrueType’s basic structure but adds other intricate structures for enhancing and describing the typographic behaviour of the font.
