About these developer tools
Small utilities you reach for a dozen times a day. Everything is processed locally in your browser, so you can paste data without sending it to a third-party server.
These are the utilities you reach for a dozen times a day and never want to think about. The deciding factor is usually not features but trust: pasting a production payload or an access token into a random website is a habit worth breaking.
Everything in this category is parsed and transformed in your own browser. Nothing is sent anywhere, which makes it safe for data you would not paste into a service you do not control.
All 2 tools in this category are free, work without an account and have no usage limits. Pick the one that matches what you need, or browse every tool.
Frequently asked questions
Is my data sent to a server?
No. JSON is parsed by the browser built-in parser and Base64 is transformed locally. Nothing leaves the page, so internal payloads stay internal.
Is Base64 a form of encryption?
No. It is a reversible encoding with no key, decodable by anyone in seconds. Never use it to protect passwords, tokens or personal data.
