JSON Image Generator

The JSON Image Generator builds a JSON object from a dropped image containing its data URI, MIME type, dimensions, and size, in pretty or minified form. It is for developers embedding image data in JSON payloads or fixtures.

Hand-assembling a JSON object with an image’s data and metadata is tedious and error-prone. Generating it locally produces valid JSON with the fields filled in.

1. Drop an image into the tool — JSON Image.
2. The JSON object is built with the data URI and metadata.
3. Switch between pretty and minified output.
4. Review the JSON.
5. Copy or download it.

• JSON with data URI and metadata
• MIME, dimensions, and size fields
• Pretty or minified output
• Generated locally — JSON Image

• Embedding an image in a JSON API fixture
• Storing an image with its metadata in a config
• Producing test data that includes an inlined image
• Bundling an image into a JSON document

• Inline only small images in JSON; reference larger ones by URL.
• Use minified output for transport and pretty output for inspection.
• Remember Base64 inflates size, so watch payload weight.

• Embedding large images in JSON, which bloats payloads significantly.
• Forgetting that Base64 in JSON adds roughly a third to the image size.
• Using inlined image JSON where a URL reference would be far lighter.
