How it works

How to use the CSS to SASS

  1. Paste CSS

    Paste your stylesheet or drop a .css file.

  2. Convert

    The output updates as you type; compile errors show their line and column.

  3. Copy the SASS

    Copy it or download it as a .sass file.

How the conversion works

The CSS is then rebuilt as nested SASS: rules that share a selector prefix are grouped, pseudo-classes become &:hover-style children, and media queries stay as blocks.

Built for developers

Why developers use it

  • Private by design

    Runs 100% in your browser. Nothing you paste is uploaded, logged or stored on a server.

    Output updates as you type, with precise error locations when something is wrong.

    No accounts, no limits, no watermarks.

FAQ

Frequently asked questions

Does it create SASS variables?

No. The converter restructures selectors into nested rules; add variables for repeated values afterwards.

Is anything sent to a server?

No. The compilers run in your browser as JavaScript/WebAssembly.

Is my data uploaded anywhere?

No. Everything runs locally in your browser — nothing you paste or open is sent to a server, logged or stored. The tool keeps working offline once the page has loaded.
