Supports PNG, JPG, BMP, WEBP up to 5MB
Available text-rendering Values
The text-rendering property accepts optimizeSpeed (fastest rendering, potentially sacrificing some quality), optimizeLegibility (prioritizes kerning and ligatures for readability), geometricPrecision (prioritizes exact geometric accuracy of glyph shapes), and auto (browser default balance), each hinting a different priority to the rendering engine.
- optimizeSpeed prioritizes fast rendering, potentially at some quality cost
- optimizeLegibility prioritizes kerning and ligature quality for readability
- geometricPrecision prioritizes exact geometric accuracy of glyph shapes
When to Adjust text-rendering Explicitly
Most SVG text renders fine with the default auto value, but optimizeLegibility becomes worth considering for body text-heavy content where kerning and ligature quality genuinely improve reading experience, while geometricPrecision matters more for technical diagrams or data visualizations where exact glyph shape accuracy affects measurement or alignment.
- Default auto value works well for the vast majority of typical SVG text content
- optimizeLegibility suits body text-heavy content where reading experience matters most
- geometricPrecision suits technical diagrams needing exact glyph shape accuracy
Frequently Asked Questions
Does text-rendering affect actual text content, or only its visual rendering?
It only affects visual rendering quality and browser rendering strategy — the actual text content, its selectability, and its accessibility to screen readers remain completely unaffected by this property.
Is there a meaningful performance difference between the text-rendering values?
For typical amounts of text, the performance difference is usually negligible, though optimizeSpeed can provide a measurable benefit specifically for pages rendering very large volumes of SVG text simultaneously.
