There is no contact form. Email lets you keep a copy of what you sent and lets us reply directly.

What to write about

  • Bug reports. A tool gives a wrong result, shows an error it should not, or does not work in your browser.
  • Corrections. Something in a tool article or guide is inaccurate or out of date.
  • Tool suggestions. A tool or option you would find useful. New tools are prioritised by these requests.
  • Privacy requests. Questions about the data described in the privacy policy, or requests to exercise your rights under GDPR or CCPA.
  • Security reports. If you find a vulnerability in the site, please email us with details before disclosing it publicly.

Writing a useful bug report

Please include:

  1. The address of the tool page, for example https://devtoolworld.com/json/json-formatter/.
  2. Your browser and operating system, for example Chrome 129 on Windows 11.
  3. What you did, what you expected, and what happened instead.
  4. A small sample input that reproduces the problem.

Do not send real secrets or personal data. Replace tokens, passwords, keys and customer details with dummy values that still show the problem. The tools process your input locally, so we cannot see what you entered unless you send it to us.

Response times

The site is run by Sarbjit Singh, and messages are answered as time allows. Bug reports and corrections are prioritised. Privacy requests are answered within the period required by applicable law; under GDPR that is normally one month.
