From binary converters and code minifiers to hash generators and email extractors. Discover a toolkit designed to optimize your workflow as a developer.
Modern web development demands efficiency. Every minute you save on repetitive tasks is a minute you can dedicate to solving complex problems, writing better code, or simply resting. Having the right tools not only speeds up your work but also reduces errors and improves code quality.
We've selected 13 free tools that cover the most common needs of programmers and developers: conversion between number systems, code minification, hash generation, data extraction, and much more. All are 100% free, work directly in your browser, and are designed to be fast and accurate.
Professional binary converter with support for decimal, hexadecimal, octal and ASCII text. Includes binary calculator with logical operations.
Convert between CSV and JSON formats with custom delimiters and header options. Ideal for APIs and data processing.
Extract email addresses from any text or webpage. Useful for marketing, scraping and data analysis.
Extract links from text, HTML or Markdown with filters by domain, protocol and more. Perfect for SEO audits and scraping.
Generate SHA-1, SHA-256, SHA-384 and SHA-512 hashes from text or files. Essential for integrity verification and security.

"Productivity in development is not about working more hours, but about removing friction. Every tool that automates a manual task is a step toward a more efficient workflow."
Minification removes unnecessary characters (spaces, comments) to reduce file size. Obfuscation renames variables and functions with short, meaningless names to make the code harder to understand. Both can be applied together, but obfuscation is optional (JS Minifier) while minification is always recommended.
Use SHA-256 for most cases: it's secure, efficient and widely compatible. SHA-512 offers greater security for critical applications. SHA-1 is deprecated and should only be used for legacy compatibility.
Use CSV-JSON Pro with the "Headers: Yes" option so the first row of the CSV becomes the JSON keys. If your CSV has no headers, the tool will generate numeric keys.
The Unix timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970 (Epoch). It's the standard way to represent time in computer systems, databases and APIs. The converter helps you work with dates accurately.
It works best with monospaced fonts (Courier, Consolas, Fira Code) and dark text on a light background. Code with syntax highlighting in colors may reduce accuracy. For best results, use clear, cropped screenshots.
Web development is a constantly evolving field, and the tools you use can make the difference between a smooth workflow and one full of friction. These 13 tools cover fundamental needs: conversion, optimization, security, extraction and generation.
