Results are provided as they are

The encoding, hashing, formatting, unit conversion, date calculation and image tools on this site are provided as they are, without warranty of any kind, express or implied — including fitness for a particular purpose, accuracy or freedom from error.

Verify before using anything in production

The implementations aim to be correct, but any software can have defects or edge cases. Do not feed results directly into production data, financial calculations, legal documents, medical decisions or security-critical work without checking them. Where it matters, cross-check against an authoritative tool or the official specification.

In particular:

• Hashing and encryption tools are for verification and conversion; they are not a security audit, and they do not mean an algorithm suits your threat model.
• Unit conversion, time zones and date arithmetic involve leap seconds, daylight saving and historical time zone changes, so results may differ from a specific business definition.
• Image tools alter file contents and metadata — always keep the original file.

Not professional advice

The content of this site, including blog posts, is for learning and reference only and does not constitute legal, financial, medical or other professional advice. Consult a qualified professional for anything that requires professional judgement.

Data never leaves your browser — which also means no backup

All computation happens locally in your browser. That is the privacy design, and it means we cannot see what you entered. It also means we cannot save or restore anything for you: after you close the page or clear browser data, unsaved results may be gone for good.

External links

This site may link to third-party websites. We do not control their content, availability or practices, are not responsible for their accuracy or safety, and a link does not imply endorsement.

Trademarks

Product names, trademarks and brands mentioned here (such as JSON, Google or Cloudflare) belong to their respective owners. This site is not affiliated with, or endorsed by, those companies.
