✓ The tool runs directly in the browser and is ready for quick checks without installing software.
✓ Input can be cleared and recalculated immediately, which is useful for repeated small tasks.
✓ Use fullscreen mode when you need more space for long text, structured data or large result blocks.
✓ Copy buttons are available on generated output so results can be reused in code, documents or support chats.
✓ Most operations are deterministic: the same input and options produce the same output.
✓ For sensitive content, prefer local browser tools and review the result before sharing it further.
