## Tips
94133
- Use URL encoding for special characters in colors (e.g., `%232563eb` for `#2563eb`)
95-
- For gradients, encode spaces as `%20` and commas as `%2C`
134+
- For gradients, you can use named colors (`red`, `blue`, `green`) or hex values
96135
- The service is stateless - perfect for dynamic content
97136
- Works in any environment that can display images from URLs
98137
- Use the web interface to visually design your perfect progress bar
99138
- Large widths (>1000px) may require horizontal scrolling in some containers
139+
- Choose PNG for platforms that don't support SVG animations (e.g., Discord, Slack)
140+
- Choose SVG for animated progress bars with stripe movement and gradient effects
