Frequently asked questions
Are Tool Matic design tools free?
Yes. Every design tool on Tool Matic is free with no account, no signup, and no usage limit. Open any tool and start using it immediately.
Do you upload my images or store my files?
No. Tool Matic design tools that handle files (image compressor, image converter, color from image, SVG optimizer, favicon generator) process the file entirely in your browser. The bytes never leave your device. You can verify this by opening DevTools and watching the Network tab while you drop a file.
Which color format should I use in CSS - HEX, RGB, HSL, or OKLCH?
Use whichever fits the job. HEX is compact and ubiquitous. RGB and RGBA add an explicit alpha channel. HSL maps to hue/saturation/lightness which is easier to tweak by hand. OKLCH is perceptually uniform, so equal numerical changes feel like equal visual changes - useful for accessible palettes. The Color Picker and HEX to RGB Converter output all of these.
How do I check whether my colors meet WCAG contrast requirements?
Compare your foreground and background colors against the WCAG 2.1 contrast ratio thresholds: 4.5:1 for body text, 3:1 for large text and UI controls, 7:1 for AAA. The Color Picker reports the contrast ratio for any two colors you select.
Which image format is best for the web - PNG, JPG, WebP, or AVIF?
For photos, AVIF gives the smallest file size with good quality, with WebP as a strong fallback. JPG is still fine when broad compatibility matters. PNG is the right choice when you need lossless quality or transparency. SVG is best for logos, icons, and anything geometric that needs to scale. Choose by content first; pick the codec that keeps the file smallest at acceptable quality.
Can I use these design tools offline?
You need a connection for the first page load. After that, the tools keep working because the work happens in your browser - no server round-trips during use.
Can I copy outputs directly into my code?
Yes. Outputs are paste-ready as HEX, RGB, HSL, OKLCH, CSS strings, SVG, or data-URIs depending on the tool. Each result has a copy button.
Are these tools open source?
Tool Matic publishes its source so anyone can inspect how each tool runs and confirm that nothing leaves the browser. Transparency is the foundation of our privacy claim - we want you to verify it, not just trust it.
