Common Use Cases

Meeting tab-required formats

Makefiles require real tab indentation — convert space-indented recipes so make stops throwing missing-separator errors.

Matching team style

Convert space-indented code to tabs before contributing to a repo whose style guide mandates tab indentation.

Shrinking indentation size

Replace 4-space runs with single tab characters to compact deeply nested files.

Frequently Asked Questions

How many spaces convert to one tab?
Every run of exactly 4 spaces becomes one tab character — the most common indentation width. Code indented with 2-space levels will convert every two levels into one tab.
Why convert indentation to tabs at all?
Tabs let each developer choose their own display width, produce smaller files, and are required by some formats like Makefiles, where recipe lines must start with a real tab character.
Is my data private when I use this tool?
Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
