JSON Ace: Online Viewer & Formatter

JSON Minifier (Compress JSON)

Use the JSONAce JSON Minifier to compress your JSON data by removing unnecessary whitespace, line breaks, and indentation. This process, also known as compacting, makes your JSON file significantly smaller and is ideal for production environments where bandwidth and storage are important.

How It Works

Minification strips all non-essential characters from your JSON string without changing its structure or data. The result is a single, continuous line of code that is functionally identical to the original but much smaller in size, making it perfect for API responses or configuration files.

  1. Navigate to the main JSONAce viewer.
  2. Paste your formatted JSON data into the input field or upload a file.
  3. Click the Minify button.
  4. Your JSON will be instantly compressed, and you can copy the result to your clipboard.
