Tools for designers who work with print.
Most online tools are built for web designers. designkit.tools was built for packaging designers, print designers, and anyone who produces files that leave the screen and land on a physical substrate.
The problems we solve are specific: a barcode that won't scan because the quiet zone was ignored. A file returned by the printer because the bleed was missing. A color approved on screen that arrived dull and flat after offset printing. An image used at 72 DPI when the process required 300. These are not hypothetical problems — they happen in every studio, on every production cycle.
All eight tools run entirely in your browser. No files are uploaded to any server. No account is required. No usage limits. The tools are free because the problems they solve are already expensive enough when they go wrong in production.
designkit.tools is made by a packaging designer with 16 years of production experience across major CPG brands. The tools reflect real workflows, not theoretical ones.
Frequently Asked Questions
Are designkit.tools tools really free?
Yes, completely. No trial period, no premium tier, no feature limits behind a paywall. All eight tools are fully functional at no cost and require no account creation. The site is supported by non-intrusive advertising, which keeps the tools free for everyone.
Do my files get uploaded to a server when I use these tools?
No. Every tool on designkit.tools processes files locally in your browser. Nothing is transmitted to any server. This means your packaging mockups, unreleased product artwork, and client files stay on your device at all times. It also means the tools work offline after the page has loaded.
What kind of designers use designkit.tools?
The tools are built primarily for packaging designers, graphic designers working in print production, and anyone involved in preparing files for offset, digital, or large-format printing. They are also useful for marketing professionals, e-commerce teams, and product managers who regularly handle artwork files and need quick technical checks without opening a full design application.
Which tool should I start with?
If you work with physical products sold in retail, start with the Barcode Generator — EAN-13 compliance is a hard requirement for distribution. If you regularly send files to print, the Bleed Calculator and Resolution Checker will prevent the most common and costly production errors. If you work with brand colors across print and digital, the Color Converter will save significant time at every handoff.
Can I use these tools for commercial projects?
Yes. The barcodes, QR codes, converted colors, and all other outputs from designkit.tools can be used freely in commercial work. The tools follow official technical specifications for each standard — EAN-13, QR Code, WCAG contrast ratios — and are suitable for files submitted to professional print production environments.
