Overview

Readme Typing SVG generates animated SVG images that display a customizable typing-and-deleting text animation, commonly used in GitHub profile READMEs to add a dynamic introduction. You configure the text, font size, color, speed, and more via URL query parameters with no API key required. Just paste the generated URL into your Markdown file and the animation appears automatically.

💡

Beginner Tip

Use the hosted demo at https://readme-typing-svg.demolab.com/demo/ to build your animation URL visually by filling out a form, then copy the generated Markdown or URL into your README. Multiple lines of text are passed as separate lines[] parameters in the URL.

Common Errors & Troubleshooting

SVG not rendering on GitHub GitHub caches images aggressively, so changes to the URL parameters may not appear immediately.
✓ GitHub may take a few minutes to refresh the cached SVG; try adding a dummy parameter like &v=2 to bust the cache.
Text getting cut off The width parameter is too small for the text content.
✓ Increase the width parameter (default is 435); use the demo tool to preview and adjust until all text fits within the SVG boundary.
Colors not applying correctly Color values with hash symbols are not URL-encoded in the query string.
✓ Encode # as %23 in the URL (e.g., color=%23FF5733 instead of color=#FF5733) or use named colors supported by SVG.
