Use API to convert HTML to PDF

The following demonstration URL shows the basic options to convert HTML to PDF by VeryPDF Web to PDF Converter Cloud API.

http://online.verypdf.com/app/onlineapi/?apikey=XXXXXXXXX&inputfile=http://www.verypdf.com&type=htmltopdfsdk

In the URL, options are separated by character "&", and the basic options are:

htmltopdfsdk: tell the Cloud API to convert HTML to PDF.
inputfile: specify an input HTML file with a URL.
apikey: use to authorize a developer's API account.

Use API to Convert HTML to image

API options for converting HTML to image are demonstrated in the following example URL.

http://online.verypdf.com/app/onlineapi/?apikey=XXXXXXXX&inputfile=http://www.verypdf.com&type=htmltoimagesdk&outputfiletype=jpg

In the URL, options "apikey" and "inputfile" are as same as those in conversion from HTML to PDF. To call the API to convert HTML to image, the option "type" should be assigned to "htmltoimagesdk", and the output image format is given by "outputfiletype=jpg". The API supports two image formats, PNG and JPG.

Demonstration PHP Code

The following is a sample PHP code demonstrating how to use the VeryPDF Web to PDF Converter Cloud API. You can directly use your registered email address for authentication instead of an API key. Our system will automatically detect whether your email is linked to a paid subscription. Emails with a paid account will have full access to all API features, while emails without a subscription will generate PDF outputs with a demo watermark applied.

Please replace the "email" placeholder in the code with your actual email to test the API functionality.
