Your API Key
Get access to your API key when you create an account. Once your account has been created, you’ll be able to process 100 documents per month for free using any of our API tools.
Your API key has automatically been inserted into the API example code. Run the sample code in your terminal to execute the API call.
Rendering a Single Page
The default is to render the first page, but you can also render any other page of the document by adding the
pages
option.
This will render the fifth page (remember pages are indexed starting from 0):
"output": {
"type": "image",
"pages": {"start": 4, "end": 4},
"format": "png",
"width": 500
}
Rendering Multiple Pages
In addition to rendering just a single page (the default is the first), you can also render multiple pages at
the same time. Simply add the pages option.
Note:
You can only render 50 pages in a single request. Requesting more than 50 pages will result in a
status 400
being returned.
The following example will return a ZIP file containing all pages:
"output": {
"type": "image",
"pages": {"start": 0, "end": -1},
"format": "png",
"width": 500
}
You can also render a subset of pages. This will render pages 2, 3, and 4:
"output": {
"type": "image",
"pages": {"start": 1, "end": 3},
"format": "png",
"width": 500
}
The files in the ZIP file will be named
<page_number>.png
Controlling Image Dimensions
You can give the output images a specific width or height, or you can render them with a specific resolution.
You can only choose one of those three options. Specifying more than one will result in a status
400
being returned.
Depending on which option you choose, one or both dimensions will be determined based on the dimensions of the page in the document. The following will go into detail about each of the three options.
Note:
There is a limit to the final resolution of the resulting images. Any image is not allowed to be
bigger than 34 million pixels (4960×7016px), regardless of the aspect ratio. Requesting a bigger image will
result in a status 400
being returned.
You can specify the width
. In this case, all rendered pages will have the same width, but they’ll
have varying heights depending on the page dimensions in the document:
"output": {
"type": "image",
"format": "png",
"width": 768
}
You can specify the height
. In this case, all rendered pages will have the same height, but they’ll
have varying widths depending on the page dimensions in the document:
"output": {
"type": "image",
"format": "png",
"height": 1024
}
And finally, you can specify the dpi
. In this case, the width and height of the rendered pages
depends only on the page dimensions:
"output": {
"type": "image",
"format": "png",
"dpi": 72
}
Rendering a Single Page
The default is to render the first page, but you can also render any other page of the document by adding the
pages
option.
This will render the fifth page (remember pages are indexed starting from 0):
"output": {
"type": "image",
"pages": {"start": 4, "end": 4},
"format": "jpg",
"width": 500
}

In addition to rendering just a single page (the default is the first), you can also render multiple pages at

"output": {
