Formatters, encoders, and generators

• Base64 Encoder & DecoderBetaEncode and decode text or files as Base64 in your browser. Handles Unicode correctly, plus a URL-safe option and file download.
• Color Converter & Contrast CheckerBetaConvert any CSS color between HEX, RGB, HSL, HWB, LAB, LCH and OKLCH, and check WCAG contrast ratios for AA/AAA, normal and large text.
• Cron Expression ExplainerBetaTurn a cron expression into a plain-English sentence and preview its next run times in any time zone. Includes a field syntax and macro cheat sheet.
• CSS Gradient GeneratorBetaBuild linear, radial, and conic gradients visually and copy the background CSS. Optional OKLCH interpolation keeps midpoints vivid instead of muddy.
• Hash GeneratorBetaCompute MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes for text or files in your browser, with hex/Base64 output and hash comparison.
• JSON FormatterBetaPretty-print, minify, or validate JSON with exact line and column on syntax errors. Sort keys, escape Unicode. Runs fully in your browser — nothing is uploaded.
• JWT DecoderBetaPaste a JWT (JSON Web Token) to see its header and payload. The signature is never verified, and everything runs in your browser.
• SQL FormatterBetaReformat SQL onto readable lines by clause (SELECT, FROM, WHERE …). Pick a dialect — MySQL, PostgreSQL, T-SQL and more. Nothing you paste leaves your browser.
• URL Encoder & DecoderBetaEncode and decode URLs and query strings. See the difference between encodeURIComponent and encodeURI with examples, and parse a full URL's structure.
• UUID Generator (v4 & v7)BetaGenerate any number of v4 or v7 UUIDs, or paste one in to see its version, variant and (for v7) embedded timestamp. Everything runs in your browser.
• XML FormatterBetaPretty-print XML with adjustable indentation, or minify it. Checks well-formedness as you go. Runs fully in your browser — nothing is uploaded.
