PixelCoder: Monochrome pixel font editor

Dive back into the golden era of 8-bit with this desktop-friendly monochrome pixel font editor.

It’s the go-to spot for demo scene artists, coders, and pixel artists, blending retro vibes with today’s ease of use and ready to integrate into your assembly code with just a copy and paste.

Diverse Font Dimensions

If you’re working on a retro-style demo or your unique project, PixelCoder supports 8×8, 8×16, 16×8, and 16×16 font styles, all designed to fit the classic bitmap style of the C64’s character memory.

Iconic C64 Fonts

I contacted Peter Kofler, who kindly allowed me to add over 600 fonts to my work from his extensive C64 collection. The collection covers everything from classic game titles to demo scene favourites. Big thanks to Peter for his fantastic contribution!

A quick breakdown of the file naming based on their sizes. All files ending with -x, -y, or -xy align with these dimensions:

-x Suffix: Indicates a 16×8 font, doubling the width

-y Suffix: Indicates an 8×16 font, doubling the height

-xy Suffix: Indicates a 16×16 font, doubling the width and height

Please contact me to request their removal if you have any copyright concerns.


Hold ALT to erase pixels or hold SHIFT to overwrite them while using the mouse. For more keyboard shortcut functions, just hover over the buttons – handy for those who like to keep things moving without fuss.

Assembler’s Dream

PixelCoder offers smooth integration with your assembler projects. With the “Show source code” feature, you can directly edit fonts as formatted source code, making it easy to copy and paste into your assembler. This real-time parsing feature also works in reverse; copy your existing assembler code into PixelCoder and instantly convert it into an editable font. This two-way interaction allows you to seamlessly transition between code and visual representation, turning your code snippets into a pixel canvas for further editing.

For the C64 Fans

PixelCoder is my way of tipping my hat to the good old Commodore 64 days. Sifting through these font files, I couldn’t help but feel a wave of nostalgia. It’s for those of us who get a kick out of bytes and have a soft spot for pixelated dreams.
