Designers and creative teams use this toolkit for the unglamorous production work that sits between concept and shipped asset — 17 tools covering text, color, images, and markup.
For content and documentation, the Markdown Table Generator and Markdown/HTML Converter speed up writing style guides, README files, or client-facing documentation, while the Text Case Converter and HTML Entities Converter clean up copy before it goes into a CMS or email template. The HTML Formatter and URL Parser help when hand-editing landing page markup or auditing UTM-tagged campaign links.
On the visual side, the Color Converter handles the constant back-and-forth between hex, RGB, and HSL values when matching brand palettes across design tools and code, and the Image Resizer preps assets for different platforms without needing a full editing suite open. QR Code Generator and QR Code Decoder cover print-to-digital handoffs — putting a scannable code on packaging or a poster, or checking what a client-supplied code actually points to. The URL Encoder/Decoder handles the encoding quirks that break links in emails and ad campaigns, and the Radiance/Irradiance Converter serves the narrower case of lighting and rendering work where physical light units matter.
Together these tools cover the small, repetitive conversions and formatting steps that eat time during production, without pretending to replace design software itself.
