What is PNG to JSON Converter?
PNG to JSON Converter extracts machine-readable data from a PNG image. The output can include dimensions, file size, average color values, and optional pixel data for APIs, indexing, analysis, or automation. The tool reads and analyzes the PNG in the browser before producing a JSON file.
How does PNG to JSON Converter work?
This tool decodes the PNG source, draws it to a browser canvas, and formats selected image properties as JSON. Metadata and color statistics stay compact, while full pixel arrays can become large because every pixel must be represented as structured text.

Download or copy
Save the JSON file or copy the data to your clipboard.
Pro Tips
- 1
The metadata-only output is small and useful for quick image information.
- 2
Including full pixel data for large images produces very large JSON files.
- 3
Use the JSON output directly in JavaScript applications without additional parsing.
- 4
For color analysis only, the statistics object provides averages without the full pixel array.
Frequently Asked Questions
Will the image be modified?
No. The tool only reads image data and outputs it as JSON. The original PNG file remains unchanged.
Is my image uploaded to a server?
No. The PNG is decoded and analyzed in the browser.
What data is in the JSON?
The output includes width, height, file size, average RGB values, and optionally the full pixel array.
How large will the JSON file be?
The metadata-only output is small. Full pixel data for large images produces very large files.
Can I convert multiple images at once?
Yes. Upload multiple files and the tool generates a separate JSON for each one.
