What this category can do
Design tools help create and inspect visual assets: colors, gradients, QR codes, barcodes, screen tests, solid colors and SVG previews. They are aimed at UI work, print handoff and display checking, not bitmap compression or office document conversion.
Most tools process input in the browser when possible. For files, tokens, documents or network checks, review the selected tool before using sensitive data.
Common use cases
- Pick colors, build gradients or show a solid color while preparing UI assets.
- Generate QR codes or barcodes for labels, posters, test data or handoff material.
- Preview SVG markup and run screen tests for dead pixels, color blocks or uniformity.
FAQ
Why do colors look different on another screen?
Calibration, color profile, brightness and panel type all affect perceived color.
What should I check before printing a QR code?
Test final size, contrast, quiet zone and material. Distortion can make scanning unreliable.
Are SVG files always safe to preview?
Treat unknown SVG as untrusted because SVG can contain active content depending on rendering.
Can generated gradients be copied to CSS?
Usually yes, but older browser support or project-specific syntax may require adjustment.
