Click the image to pick a color, or use exact image coordinates below. Palette extraction ignores mostly transparent pixels and uses a downscaled sample.

Choose an image to pick a color.

Frequently asked questions

Is my image uploaded?

No. Image processing and entered options stay on your device. Helphonic serves the tool, checks your access and receives non-content usage metadata; image pixels, SVG source and chosen colors are not sent to Helphonic or analytics.

How does usage work?

This tool launches with unlimited free usage for guests, registered users and active paid users. Administrators can configure limits later. One successful export counts as one operation, even when it includes several download files.

Are edits saved to my account?

No. Download the result before leaving the page. Your source file is not changed. Device safety limits still apply, and speed depends on your browser and device.

How to use

Color Picker & Palette Extractor

Learn how to use Color Picker & Palette Extractor: step-by-step instructions, settings, export options, privacy, limits and troubleshooting.

Step-by-step instructions

  1. Choose one image and select the number of palette colors.
  2. Click the preview or enter image coordinates to inspect a pixel.
  3. Choose text and background HEX colors to compare contrast.
  4. Create the download to save palette JSON and an SVG swatch strip.
Options and important details

Palette extraction samples a downscaled image and groups similar colors. Mostly transparent pixels are ignored; gradients may produce fewer distinct colors than requested. Pixel picking samples the full-resolution source.

The contrast ratio uses relative luminance for two solid sRGB colors. Thresholds shown are 4.5:1 for AA normal text, 7:1 for AAA normal text and 3:1 for AA large text. Passing one color comparison is not a full accessibility audit.

The exported JSON contains the displayed palette and the selected contrast colors. It does not include the source image, filename or image metadata.

Privacy and device safety

Files and entered content are processed locally. Helphonic checks access and records non-content operation metadata only. Download your results before leaving the page.

One source image is allowed per operation. Raster inputs and exports are limited to 16 megapixels and 8000 pixels per side. Administrative file-size limits may be lower.

Processing and privacy

Files and entered content are processed on your device in this browser tab. File contents and results are not uploaded to Helphonic or sent to analytics. The page still contacts Helphonic to load its tools, check access and confirm non-content usage information. Work is not saved to your account; download or copy results before leaving or reloading the page.

If an operation cannot finish

Use a current browser and smaller inputs if the tab runs out of memory. Some tools download a local processing library or model on first use, so an internet connection is needed even though your content stays on the device.

If the tool reports that access or limits changed, review the current policy and run it again. If usage confirmation is uncertain after an interrupted connection, a retry can count as another operation. Download completed work before reloading; this site does not keep a recovery copy.

About this tool

Choose a JPG, PNG or WebP image. Click the preview or enter exact pixel coordinates to inspect a color and its opacity.
