Do all developer utility tools work offline?
Yes. The JSON Formatter, Base64 Encoder & Decoder, Regex Tester, URL Encoder & Decoder, and Text Diff Checker run entirely in your browser. Once the page has loaded, no connection to our servers is needed for calculations.
Can I report a wrong result or suggest a feature?
Please do — it helps us improve. Include the tool name, the inputs you entered, and the result you expected. We usually fix confirmed issues within a few days.
Is my data shared when I use the contact form?
No. Your message is used only to answer your inquiry and is never shared with third parties. There is no newsletter and no spam — you hear from us only when we reply.
