Frequently Asked Questions

What is CSS Filter Generator?
Generate CSS filter effects online for free. Adjust blur, brightness, contrast, saturation, hue rotation, and grayscale with live image filter preview.
Are generated values truly random?
The tool uses the browser's built-in cryptographic random number generator (crypto.getRandomValues) when security matters, and high-quality pseudo-random algorithms for general-purpose generation. This ensures unpredictable, non-repeating output.
Can I customize the output?
Yes, the generator provides controls such as sliders, toggles, and selection menus to fine-tune the output to your exact requirements. Adjust length, character sets, formats, and other parameters before generating.
How are random values generated?
Values are generated entirely in your browser using JavaScript's native APIs. No external service or server call is involved, which means generation is instant and your output is never transmitted anywhere.
Is CSS Filter Generator free to use?
Yes, this generator is free to use with no limits on how many values you can create. No signup or account is needed.
Is my data safe when using CSS Filter Generator?
Yes, all generation happens in your browser. Nothing is sent to a server, and no generated values are stored or tracked.
