Built by a designer.
For designers.
designkit.tools is a free collection of practical tools for graphic designers, packaging designers and creative professionals who need reliable resources without friction.
Why this exists
Every tool here was built to solve a real problem I encounter in daily design work. Not a theoretical problem — a practical one. The kind that makes you open five browser tabs, lose time, lose focus, and still get a mediocre result.
Barcode generators that don't export to SVG. Color converters that skip CMYK. Resolution checkers that give vague answers. Bleed calculators buried inside paid software. I built designkit.tools to fix all of that in one place, for free, with no account required.
Every tool runs entirely in your browser. Nothing is uploaded to any server. No data collected. No subscription. No trial. Just open it and use it.
Who made this
I'm Diego Bolinelli, a packaging and branding designer with over 16 years of experience working on products for major consumer brands across Brazil. I've spent my career at the intersection of design strategy, print production and e-commerce — which means I understand what happens to a design after it leaves the screen.
I know what a barcode area of silence actually means in a printing audit. I know why a 72 DPI image approved on screen can come back blurry from the printer. I know what appetite appeal means and why green lime is the most unpredictable color in CMYK.
designkit.tools is the set of tools I wish I had when I started. Built with technical depth and without the noise.
