CSS Minifier & Beautifier
Optimise or reformat your styles with drag-and-drop uploads, live previews, and clear diagnostics.
Why minify CSS?
- Smaller files mean faster downloads and better scores on performance audits.
- Beautify mode expands code for code reviews or onboarding teammates.
- Use descriptive class names and group related rules for clarity before minifying.
Privacy-first processing every time
WizardOfAZ tools do not need registrations, no accounts or sign-up required. Totally Free.
- Local only: There are many tools like Text tools, some CSV tools, List tools etc. that are only processed on your browser. Data and Documents are transformed on your machine, so nothing is sent to our servers.
- Transparent progress: Watch the processing banner appear as soon as work begins and know exactly when it completes.
- Clear safeguards: Every tool links directly to our privacy policy and has been reviewed for accessibility.
- Secure Process: Some Tools need to be processed in the servers so the Old Wizard processes your files securely on our servers, keeping them for up to 1 hour so your tool can finish its work—after that, they are automatically deleted after 1 Hour.
“The wizard does everything I need. I can merge sensitive PDFs without a second thought.”
