Sometimes 'small text' means an image file — a PNG of styled lettering for a graphic — and sometimes it means characters you paste into a field. They solve different problems. For the paste-anywhere version, use the small text generator.
This guide lays out when each one is the right call.
What copy-paste Unicode gives you
Real text: selectable, searchable, editable, readable by screen readers, and it counts toward character limits. It works in any text field — bio, caption, message, document. The look is limited to what Unicode defines, and it can show as boxes on devices missing a glyph.
What a PNG gives you
Total control of the look — any font, colour, effect — and it renders identically everywhere because it's pixels, not characters. But it's not text: it can't be searched, selected, or read aloud, it can't go in a plain-text field like a bio, and it adds file weight.
Which to use when
Bio, username area, caption, chat, document body: copy-paste Unicode, always — a PNG can't go there. Logo, thumbnail, story graphic, header image: a PNG or SVG, because you want a specific typeface and guaranteed rendering. Never use a text image for body content you want found in search.
Getting a PNG if you need one
This site's generator produces Unicode text, not image files. For a PNG, screenshot the styled result or set the text in an image editor with the font you want. Keep alt text on it so it's still accessible.
