PNG to CSV Converter

Pixel Data Mode

This mode extracts information about individual pixels from the image. You can adjust the sampling rate to reduce the output size for large images. Each row in the CSV represents a single pixel, with options to include:

• X/Y coordinates of the pixel
• Red, Green, Blue, and Alpha (transparency) values
• Hexadecimal color code representation

Ideal for detailed image analysis, creating pointillist visualizations, or extracting specific pixel information.

Color Analysis Mode

This mode analyzes the color distribution in the image. It counts the occurrence of each unique color and provides frequency information. Options include:

• Extracting all unique colors or only the most frequently used colors
• Setting a maximum number of colors to include in the output
• Including or excluding fully transparent pixels

Perfect for palette extraction, color scheme analysis, or studying the color composition of images.

Metadata Mode

This mode extracts overall information about the image, including:

• Image dimensions (width, height) and aspect ratio
• Average RGB color values across the image
• Average luminance (brightness) and predominant tone
• Percentage of transparent pixels

Useful for cataloging images, creating image databases, or quick analysis of image characteristics.

What's the maximum image size this tool can handle?

The maximum file size for upload is 10MB. However, for large images (high resolution), we recommend using the pixel sampling option in Pixel Data mode to extract a representative subset of pixels rather than every pixel. This improves performance and produces more manageable CSV files.

Why would I use the Color Analysis mode instead of Pixel Data mode?

Color Analysis mode focuses on the distribution of colors rather than individual pixels. This is useful when you're interested in the overall color composition of an image rather than specific pixel locations. It produces a much smaller CSV file with statistics about color frequency, which is ideal for palette extraction or studying color usage in images.

Are my image files stored on your servers?

No, all processing happens directly in your browser using client-side JavaScript. Your image files are never uploaded to our servers, ensuring complete privacy and security.

Can I use this tool for images other than PNG?

This tool is specifically designed for PNG images. PNG is ideal because it supports transparency (alpha channel) and lossless compression, ensuring accurate pixel data extraction. If you need to convert other image formats to CSV, consider converting them to PNG first.

What's the format of the CSV output?

The CSV format depends on the extraction mode and options you select. By default, it includes a header row and the data columns you've enabled (position, RGBA values, hex codes). Each row represents either a pixel (in Pixel Data mode), a unique color (in Color Analysis mode), or a property-value pair (in Metadata mode). The columns are separated by commas, following standard CSV format.
