Quick Start
When working with code, HeronTool offers a suite of practical tools. First, open the Code Highlighter to add syntax highlighting to code blocks for better readability and sharing. Then, use the Base Converter to easily convert values between binary, octal, decimal, and hexadecimal – handy for debugging and low-level development.
Format & Beautify
Formatting code is a daily necessity. Use the XML Formatter to beautify XML files with one click, keeping structures clear. For SVG images, use the SVG Optimizer to remove redundant data, reduce file size, and boost loading speed.
Batch Edit & Compare
Need to batch process text lines? Add Line Numbers adds line numbers for easy reference; Add Prefix/Suffix allows adding a uniform prefix or suffix to multiple lines simultaneously; Quote Lines wraps each line in quotes – ideal for generating string arrays. For version checking, use the Text Diff to highlight differences between two files and quickly pinpoint changes.
FAQ
Q: What languages do these tools support?
A: Code Highlighter supports over 180 languages; XML Formatter works with any XML document; other tools are plain-text based and language-agnostic.
Q: Is my data secure?
A: All processing occurs locally in your browser. Your code is never uploaded to our servers – fully private.
Q: Can I process multiple files at once?
A: Most tools handle one text block at a time, but you can loop copy-paste. Batch prefix/suffix and quote lines work on multiple lines, effectively batch processing.
