Stamp Font Engine++ Font Injector

1. Font Settings

Font File

Choose file No file chosen

Name of Font to be used in Project

Character Set to Inject

Presets Basic Default Expanded Expanded+ Expanded++

If the font name already exists in the sprite, all previously-injected characters under the font name will be removed before injecting the new character set using the new font file.

It is best not to inject excessive numbers of unused characters. Chromium-based browsers, including Chrome and Edge, have a bug that crashes the Scratch editor and project player when too many images are loaded.

Disable kerning (reduces JSON size, especially when injecting a lot of characters in one font)

2. Project Settings

SB3 Project File with Stamp Font Engine++ Sprite

Choose file No file chosen

The project must contain a Stamp Font Engine++ sprite. Using a blank project won’t work.

Name of Stamp Font Engine Sprite++ in Project

Reset font data instead of injecting font

3. Download

Inject and Download

The resulting SB3 file should automatically download after clicking the button above (this may take several seconds). If not, something has gone wrong.

If the resulting file size is too large, try saving the project in Scratch Desktop.
