About Cirelay Tools

Cirelay Tools is a network of 20 single-purpose web tools published by Cirelay, the team behind Findora.

How the tools are built

• In your browser. Image conversion uses the browser’s own canvas encoder, hashing uses the Web Crypto API, and PDFs are assembled byte by byte on your device.
• One address per job. Each tool lives on its own subdomain of cirelay.com, so the address tells you what it does, and every page links to related tools.
• Shown formulas. Calculators explain the formula they use so you can check the result. Mortgage maths follows Canadian semi-annual compounding when you choose it.
• Tested. Every build is checked for broken links and every tool is exercised in a real browser before it ships.

Accuracy

Unit factors use exact international definitions (for example, 1 inch = 2.54 cm and 1 lb = 0.45359237 kg). Exchange rates are reference rates, not the rate a bank or card will charge. Health and loan results are estimates and are not financial or medical advice.
