JSON formatter, Base64, URL encode, regex, passwords, color converter, contrast, cron, timestamp, minifier. All in real time.
Pretty‑print and validate JSON. Paste minified JSON to get readable indented output. Essential for API debugging.
💡 Always validate JSON before using in code.Convert text to Base64 and vice versa. Used for data URIs, email attachments, and API tokens.
💡 Base64 increases size by ~33%.Encode special characters for safe URL transmission. Use decode to read encoded query parameters.
💡 Always encode user‑generated URL parameters.Test regular expressions on sample text. See all matches and count. Perfect for pattern validation.
💡 Use flags like /g for global search.Create strong random passwords with customizable character sets. Use long passwords (12+ chars) for security.
💡 Never reuse passwords across sites.Convert between color formats. Enter HEX (#RRGGBB), RGB (rgb(52,152,219)), or HSL (hsl(204,70%,53%)).
💡 Use for CSS, design systems, or data visualization.Check WCAG 2.1 contrast ratio between foreground and background colors. Ensure accessibility for text and UI.
💡 Aim for 4.5:1 for normal text, 3:1 for large text.Interpret cron syntax: minute, hour, day of month, month, day of week. Get human description and next run time (sample).
💡 Common: "0 9 * * *" = every day at 9:00.Convert Unix timestamps (seconds since 1970) to readable dates and vice versa. Useful for logs and APIs.
💡 JavaScript uses milliseconds; divide by 1000.Remove extra spaces, tabs, and line breaks. Useful for compacting text or preparing for HTML/JSON minification.
💡 Does not encode special characters.
