Free everyday utility tools
ToolLumo utility tools are designed for small tasks that should take seconds rather than require an app install or account. Generate a static QR code for a link or text, or solve common percentage calculations directly in your browser.
What you can do with these tools
The QR code generator creates downloadable PNG and SVG files that can be tested before use. The percentage calculator covers three common questions: what a percentage of a number is, what percentage one number is of another, and the percentage change between two values. Each utility has a dedicated URL, clear instructions and examples so it can be bookmarked and found again easily.
Why each tool has its own page
Each task has a permanent, descriptive URL with instructions, limitations and related links. That makes it easier to bookmark the exact utility you need and helps search engines understand what each ToolLumo page is actually for.
