AMP Font Viewer: Preview, Inspect, and Optimize Web Fonts

AMP Font Viewer — Fast, Simple Font Preview Tool

What it is

AMP Font Viewer is a lightweight web tool for previewing and comparing fonts quickly. It’s designed for fast iteration when choosing typefaces for AMP pages or any web project where performance and clarity matter.

Key features

• Instant previews: Type custom text and see rendered results immediately.
• Multiple font sources: Load local fonts, Google Fonts, or custom URL-hosted fonts.
• Side-by-side comparison: View two or more fonts at once to compare weight, spacing, and style.
• Performance indicators: Quick metrics showing font file sizes and estimated impact on page load.
• Adjustable settings: Font size, line-height, letter-spacing, weight, and color controls.
• Export CSS snippets: Copy ready-to-use @font-face or Google Fonts link tags and small CSS rules for quick integration.

Why it helps

• Saves time selecting typography by removing the need to edit code for each change.
• Helps balance aesthetics and performance by showing file-size impact and lightweight alternatives.
• Useful for AMP pages where minimizing resources and ensuring fast rendering are critical.

How to use (quick steps)

1. Enter your sample text in the preview box.
2. Add fonts: choose from Google Fonts, paste a font URL, or upload a local font file.
3. Adjust size, weight, spacing, and color using the controls.
4. Use the side-by-side view to compare candidates.
5. Copy the generated CSS or font link and paste into your AMP page head (use rel=“preload” or rel=“stylesheet” as appropriate for AMP requirements).

Tips for AMP optimization

• Prefer system fonts or Google Fonts with smaller subsets to reduce load.
• Use font-display: swap in your CSS to avoid invisible text during loading.
• Preload critical fonts and defer nonessential font loads.
• Subset fonts to include only used characters when possible.

Example CSS snippet

@font-face {
font-family: “ExampleFont”;

  font-style: normal;
}
