About the Spaces to Tabs Converter
Spaces to Tabs Converter replaces each run of N spaces with a single tab character, turning space-indented text back into tab indentation. Set how many spaces make one tab and the tool rewrites your indentation to match.
It is built for developers who prefer tabs, teams enforcing a tab-based style, and anyone converting pasted content to a compact format. Convert only the leading whitespace to keep spacing inside your lines untouched, or convert every qualifying run.
All processing is done locally in your browser, so your source is never uploaded. Your code stays private and the converter continues to work even without an internet connection.
Frequently asked questions
How does spaces-to-tabs conversion work?
You choose how many spaces equal one tab, and each matching run of spaces is replaced by a single tab character.
Can I convert only the indentation?
Yes. Turn on “Leading spaces only” and only the spaces at the start of each line become tabs, leaving inner spacing intact.
Why would I use tabs instead of spaces?
Tabs are a single character, so they make files smaller and let each developer set their preferred visual width in their editor.
Is my code uploaded anywhere?
No. Everything runs in your browser, so your code stays on your device and the tool works offline.
