Overview
Design work requires precise color control, optimized assets, and accessible contrast. This catalog brings together tools for gradients, palettes, SVG optimization, favicon generation, and more. Use it as a lightweight companion to speed up visual workflows and keep assets consistent across products.
Design workflows stall on asset prep
Design teams often spend time exporting and reformatting assets for different platforms. Without quick conversion tools, every iteration becomes a manual task.
Accessibility and contrast compliance are frequently checked late in the process, resulting in rework. Inline tools help validate color choices early.
Maintaining consistent visual systems requires standardized gradients, palettes, and ratios. A reliable toolkit helps enforce those standards.

Best Practices
- Validate contrast early to avoid late-stage redesigns.
- Use consistent color tokens across products.
- Optimize SVGs before committing them to production.
- Limit Base64 usage to small icons or critical assets.
- Store gradient presets in design systems.
- Export favicons in standard sizes for broad compatibility.
- Keep aspect ratios consistent across breakpoints.
FAQs
Are design assets uploaded anywhere?
No. All tools process files locally.
Do gradients output CSS?
Yes. You can copy CSS-ready gradient code.
Can I generate color palettes?
Yes. Use the shade generator to create variants.
Are contrast checks WCAG-based?
Yes. The checker uses WCAG contrast ratio guidelines.
Can I optimize SVGs safely?
Yes. The optimizer removes unnecessary markup to reduce size.
Do you support WebP conversion?
Yes. Convert WebP images to PNG or JPG.
Can I create favicons in multiple sizes?
Yes. The generator outputs a set of favicon sizes.
Is Base64 safe for production?
Base64 is useful for small assets but can increase file size if overused.
