Built for Base64 image JSON

The generated object is convenient for API examples, fixtures, and applications that transport binary content in JSON.

No registration, watermark, queue, or server upload is required.

Use Base64 wisely

Base64 is ideal for text-only APIs, small embedded assets, test fixtures, and portable documents. It increases payload size, so external files are usually better for large public assets.

Frequently asked questions

Is the image to base64 json converter private?

Yes. The generated object is convenient for API examples, fixtures, and applications that transport binary content in JSON. All processing happens locally in your browser — nothing is uploaded to our servers.

What fields are included in the JSON object?

The output includes filename, MIME type, file size, and the Base64 data string — useful for API mocks and test fixtures.

Can I use this JSON in a REST API request body?

Yes, when your API expects binary content as a Base64 string inside JSON. Check your API schema for the exact field names required.

When should I use Base64 for Base64 image JSON?

Use it when a text-only channel or API must carry binary data, or when a small Base64 image JSON asset needs to live inside a self-contained document. Prefer separate files for large, cacheable public assets.
