Why Convert JPG to JSON?
Converting a JPG image to JSON provides a structured, text-based representation of the image's data, enabling:
- Web Applications: Dynamically display or manipulate images using the JSON data.
- Image Analysis: Easily access and process pixel data for analysis or filtering.
- Data Processing: Integrate image data into data pipelines or machine learning models.
- Storage & Transmission: Store and transmit image data in a text-based format.
- Game Development: Use JSON to represent sprite sheets or level maps.
Key Features

Frequently Asked Questions
What does "Max Processing Width" do?
This setting limits the width of the image *during processing*. Larger images, especially with pixel data included, can take longer to convert and produce large JSON files. Reducing the processing width can significantly improve performance. The original image is not modified.
What are the different pixel data formats?
The tool offers three pixel data formats:
- RGBA: An object with `r`, `g`, `b`, and `a` (alpha/transparency) properties for each pixel. Provides the most detailed color information.
- Hex: A string representing the color in hexadecimal format (e.g., `#FF0000` for red). More compact than RGBA.
- RGB Array: An array `[r, g, b]` representing the red, green and blue colour values.
What happens if I include pixel data for very large images?
Including pixel data for large images can create *very large* JSON files. Use this option carefully and consider reducing the "Max Processing Width".
Are my uploaded images stored?
No, your images are processed directly in your browser and are not uploaded to any server.
