About Integrity

Our Mission

Integrity provides install-free, login-free web tools for common engineering tasks. All processing happens in your browser — your data never leaves your machine. We focus on utilities such as formatting, encoding, checksum validation, and quick diagnostics that developers reach for every day.

Available Tools

We offer 16 tools in both English and Korean. Integrity started as a personal collection of tools I repeatedly searched for and now focuses on practical utilities that can run reliably in static HTML pages.

• JSON Formatter: Beautify, minify, and validate JSON
• Base64 Encoder/Decoder: Encode and decode text or files
• URL Encoder/Decoder: Encode and decode URL-safe strings
• UUID Generator: Generate single or bulk UUID v4
• Timestamp Converter: Convert between Unix timestamp and date
• Color Converter: Convert between HEX, RGB, HSL, and Tailwind colors
• File Hash Generator/Verifier: Generate SHA-256, MD5, SHA-1 checksums and verify integrity
• File Compare: Check whether two files are identical
• Character Counter: Count characters, words, bytes, and sentences in real time
• Text Hash Generator: Generate hash values from text input
• Text Diff: Visualize differences between two texts
• CSS One-Liner: Collapse multi-line CSS into one line per selector
• SEO Meta Checker: Analyze and validate meta tags
• HTTP Header Analyzer: Inspect response headers for security and caching
• HTML Code Validator: Check tag errors, accessibility issues, and unused CSS
• Image to Base64: Convert image files to Data URI format

Operating Principles

• Browser-first processing: All computation runs locally. You can safely use sensitive data.
• Clear input/output behavior: Each tool includes usage guidance, real-world scenarios, caveats, and FAQs.
• Continuous improvement: We act on user feedback and bug reports to refine the tools over time.
• Free with ads: All tools are free with no feature limits. Advertising revenue sustains the service.

Content Update Policy

Tool pages are updated with usage scenarios, caveats, and FAQs on an ongoing basis. When features or policies change, we revise both the interface behavior and supporting documentation. If you notice outdated information or errors, please let us know.

Who Runs Integrity

Integrity is planned and operated by CJY, a developer with over ten years of hands-on web experience — building and running websites and e-commerce stores, managing traffic analytics (Google Tag Manager, Search Console), and operating Cloudflare-based infrastructure. The tools grew out of conversion and validation tasks that came up repeatedly in that work, and each tool page's usage scenarios and caveats are written and updated from real operating experience.

Quality Standard

Our baseline is accuracy, performance, and accessibility. We maintain validation logic, predictable error handling, and straightforward workflows for daily use. Browser compatibility is tested against the latest versions of Chrome, Firefox, Safari, and Edge.
