Character-Level Formatting

The typeface applied to selected characters. FlashFX provides access to:

• -System fonts — fonts installed on the local operating system and accessible to the browser
• -Google Fonts — the full Google Fonts library, loaded on demand (requires internet connection on first use)
• -Uploaded fonts — custom font files (OTF, TTF, WOFF, WOFF2) uploaded by the user to their account

Font Search: The font family dropdown includes a search field. Type any portion of a font name to filter results.

Font Preview: Each font in the dropdown previews with a short text sample in that typeface.

The weight variant of the selected font family. Available weights depend on the font. Common weights:

Italic or Oblique, when available in the font family. Italic is a designed alternate style; Oblique is a mechanical slant applied to the regular style when a true italic is not available.

Faux Italic: When a true italic is not available, FlashFX can apply a synthetic oblique slant. This is a visual approximation and is generally less refined than a true italic. Indicated by an asterisk in the style selector.

The size of the text in pixels. Range: 1px to 2000px. Fractional values are supported (e.g., 14.5px).

Relative Sizing: While multiple characters are selected with different sizes, changing the font size applies relative scaling: typing +4 increases all selected characters by 4px regardless of their individual starting sizes.

Underline: A line drawn beneath the text baseline.

• -Style: Solid, Dashed, Dotted, Double
• -Color: Independent of the text fill color
• -Thickness: Weight of the underline in pixels
• -Offset: Vertical distance from the baseline in pixels

Strikethrough: A line drawn through the middle of the text. Style, Color, and Thickness controls are identical to Underline.

Superscript: Reduces character size and raises it above the baseline. Used for footnote markers, exponents.

Subscript: Reduces character size and lowers it below the baseline. Used for chemical formulas.

Size reduction factor and vertical offset are configurable in Typography Settings.

All Caps: Converts all selected characters to uppercase in the rendered output. The underlying text data is not modified.

Small Caps: Renders lowercase letters as uppercase letters at a reduced size (typically 70-80% of the regular cap height). When the font includes OpenType small caps glyphs, those are used; otherwise FlashFX synthesizes them.

Adjusts the uniform spacing between all characters in a selection. Measured in em units (1000 = 1em) or pixels, depending on the unit setting.

• -Positive values spread characters apart
• -Negative values bring characters closer together
• -0 = the font's default spacing

Adjusts the spacing between two specific adjacent characters. Distinct from tracking, which applies uniformly to all characters in a selection.

Auto Kerning: FlashFX applies the font's built-in kerning pairs automatically.

Optical Kerning: An algorithmic kerning mode that analyzes the actual shapes of adjacent characters and applies spacing corrections even when the font's kerning table does not include that pair.

Manual Kerning: Place the cursor between two characters and adjust the kerning value in the Properties Panel to apply a custom correction.

Moves selected characters vertically relative to the text baseline without changing font size or line height. Positive values move characters up; negative values move them down.

Useful for: custom superscript and subscript refinement, mixed-size type alignment, and creative typographic treatments.

Horizontal Scale: Widens (above 100%) or narrows (below 100%) the character horizontally.

Vertical Scale: Stretches (above 100%) or squashes (below 100%) the character vertically.

These are non-typographic transforms applied after rendering the glyph. They do not change the font's optical proportions the way a condensed or extended font variant would.
