Affiliate disclosure

Last updated: 13 November 2026

Handy Tools Desk is free. To pay for it we may show advertising and, on some pages, links to products or services from partners. If you buy through a partner link we may receive a commission, at no extra cost to you.

• Partner boxes are always marked “Ad · Affiliate link”, and their links carry rel="sponsored" so search engines know they are paid.
• Partners never pay for a tool’s result or for what our explanations say. Calculator figures come from official sources.
• Boxes from Rank or Design, the studio that makes this site, are marked “From the makers of this site”.
