A few useful things, on us.
Convert palette files, generate color code, or check WCAG contrast directly in your browser. No account, no download, and no uploading your files.
Each tool runs locally in your browser. Your files and color values aren't uploaded or sent to a server for processing.
Once the page has loaded, the tools continue working even without an internet connection.
They do the same arithmetic Suisai does on the desktop. If one of them finishes your job, then I am glad we could help.
Convert ASE and GPL files
Choose an Adobe Swatch Exchange or GIMP palette, or drag it into the converter. It works out which format the file is in and converts it to the other, keeping the swatch colors and the names both formats support.
The source is open under the MIT license, so you can read exactly how your file is handled rather than take our word for it.
Turn a color into code
Enter a HEX, RGB, or HSL value and get it back as Swift, SwiftUI, UIKit, AppKit, CSS, and more, with the decimal precision set where you want it.
The free converter handles one color at a time, in a selection of formats. The application carries the full set of forty-three and exports whole named palettes.
Check color contrast against WCAG 2.2
Enter two colors to see their contrast ratio and whether they meet WCAG 2.2 AA or AAA thresholds for your intended text size and weight. Use Reach to find an adjustment when a combination falls short.
You can also paste up to ten colors and compare every foreground/background combination in a contrast matrix.
Some things should just be useful.
Not every color-related task needs a full application. Sometimes you just want to convert a palette, generate a color value, or check whether two colors meet a contrast requirement.
We built these tools because they're useful for exactly those occasions.
They're free, with no account, no uploads, and no expiry. You don't have to purchase Suisai to use them, and you won't be asked to sign up for anything.
If they're all you need, we're happy they've helped.
More tools, working together.
The free tools are useful for individual tasks. Suisai brings those capabilities together with screen sampling, photograph extraction, editable palettes, harmonies, color ramps, spectral mixing, color-vision simulation, and a searchable Palette Library.
Work with colors across different applications and projects, and export them in forty-three individual color code formats or thirteen whole-palette formats.
One purchase. No subscription. No account or analytics.
If Suisai isn't right for you, a full refund is available within 30 days for direct purchases via Paddle. No reason needed.
