FlyUtils

CSS Filter Generator

Pick a target hex color to generate a CSS filter() approximation (invert, sepia, saturate, hue-rotate, brightness, contrast) useful for monochrome icons.

How it works

  1. 1

    Fill in the form fields the tool shows.

  2. 2

    Change modes or toggles if available.

  3. 3

    Copy the generated output when it looks right (often updates live).

Why use this tool

  • Runs entirely in your browser — nothing is uploaded to a server.
  • 100% free, no sign-up, no limits.
  • Works in any modern browser — no app install, no extension, no account.

Recoloring icons with CSS filters

When you cannot swap SVG fill easily, a filter stack can tint a black asset toward a brand color. Approximations are rarely perfect—check the preview and tweak if needed.

How to use CSS Filter Generator

Complete the fields in CSS Filter Generator. Output is produced in your browser from those inputs — copy it when ready.

Tips for better results

Empty optional fields if you want a minimal result. Invalid combinations should surface an error message.

Privacy and offline-friendly processing

Whenever possible, CSS Filter Generator processes your data locally with JavaScript in this page. That means drafts, secrets, and unfinished work stay on your device by default. Prefer this workflow when you do not want to upload sensitive text, tokens, passwords, or files to a third-party service.

Frequently asked questions

Does this work on any image?

It is designed for black (or near-black) icons. Colored photos will not map cleanly to a single target color.

Why is there a loss value?

Loss estimates how far the filtered result is from the target color; lower is closer.

Is my data uploaded when I use this tool?

For most FlyUtils tools, no. Processing happens in your browser with JavaScript. If a tool ever needs a server, that will be stated clearly on the page.

Is CSS Filter Generator free to use?

Yes. CSS Filter Generator is free, with no sign-up and no artificial usage caps for normal personal and work use.

Does CSS Filter Generator work on mobile?

Yes. The page is mobile-first, so you can paste input, tweak options, and copy results from a phone or tablet.
