What is PNG to CSV Converter?
PNG to CSV Converter extracts RGB pixel values from a PNG image and writes them as comma-separated rows. Each row records a pixel position and color channels for spreadsheet analysis, scripts, machine learning experiments, and scientific image processing. The tool reads and scans the PNG in the browser.
How does PNG to CSV Converter work?
This tool decodes the PNG source, draws it to canvas, and reads pixel values from the canvas buffer. The CSV output includes X, Y, Red, Green, and Blue columns for each pixel, so large images produce large CSV files.

Pro Tips
- 1
Large images produce very large CSV files. Resize the image first to reduce output size.
- 2
The CSV includes X, Y, R, G, B columns for each pixel.
- 3
Open the CSV in Excel, Google Sheets, or any data analysis tool.
- 4
PNG transparency data (alpha channel) is not included in the CSV output by default.
Frequently Asked Questions
Will the image be modified?
No. The tool only reads pixel data and outputs it as text. The original PNG file remains unchanged.
Is my image uploaded to a server?
No. The PNG is decoded and scanned in the browser.
What data is in the CSV?
Each row contains X coordinate, Y coordinate, Red, Green, and Blue values for one pixel.
How large will the CSV be?
A 1000x1000 image produces about 1 million rows. Resize first for large images.
Can I convert multiple images at once?
Yes. Upload multiple files and the tool generates a separate CSV for each one.
