How do I increase the DPI for printing?

You can change the DPI with a "dpi" integer min: 72 max: 600 flag in your API requests, as shown in the example below .

{
  "template": "MvqYnLpgQwQ0DPKxye",
  "formats": ["png", "jpg", "pdf", "webp"],
  "dpi": 150,
  "modifications": {
    "objects": [
      {
        "name": "title",
        "text": "Hello World",
        "color": "#FF5733"
      },
      {
        "name": "avatar",
        "background-image": "https://example.com/photo.jpg"
      },
      {
        "name": "background",
        "background-color": "#d6d0e15e"
      }
    ]
  }
}

Note: Changes to DPI have no visible effect on the dimensions of your images. This flag embeds the DPI in the metadata of the output image for print sizing.
