POST /v1/pdf/convert/from/html

This API converts a RAW HTML code into a PDF document and process any JavaScript which the webpage triggers when it loads. For example if the the webpage triggers a JavaScript popup window then that will be included in the conversion process. There is no option to disable JavaScript on the supplied RAW HTML code.

Request body

Attributes are case-sensitive and should be inside JSON for POST request. for example: { "html": "<h1>Hello</h1>" } No query parameters accepted.
Remember to ensure that request sizes are less than 4 mb in file size. For more information, see Request Size Limits.
string
required

string
default:"print"
Controls how content is rendered when converting to PDF. Options: print (uses print styles), screen (uses screen styles), none (no media type applied).
boolean
default:"false"
Controls how thoroughly the converter waits for a page to load before converting HTML to PDF --- false waits for full page load, while true speeds up conversion by waiting only for minimal loading.
string
Set this to can add user definable HTML for the header to be applied on every page header. The format is html.
Set this to can add user definable HTML for the footer to be applied on every page bottom. The format is html.
boolean
default:"false"
Set async to true for long processes to run in the background, API will then return a jobId which you can use with the Background Job Check endpoint. Also see Webhooks & Callbacks
string
The callback URL (or Webhook) used to receive the POST data. see Webhooks & Callbacks. This is only applicable when async is set to true.
string
File name for the generated output, the input must be in string format.
integer
default:"60"
Set the expiration time for the output link in minutes. After this specified duration, any generated output file(s) will be automatically deleted from PDF.co Temporary Files Storage. The maximum duration for link expiration varies based on your current subscription plan. To store permanent input files (e.g. re-usable images, pdf templates, documents) consider using PDF.co Built-In Files Storage.

The header and footer parameters can contain valid HTML markup with the following classes used to inject printing values into them:
  • date: formatted print date
  • title: document title
  • url: document location
  • pageNumber: current page number
  • totalPages: total pages in the document
img: tag is supported in both the header and footer parameter, provided that the src attribute is specified as a base64-encoded string. For example, the following markup will generate Page N of NN page numbering:
An example with an advanced header and footer. Note that the top and bottom page margins are important because page content may overlap the footer or header.
If you use JSON as input then make sure to escape it first (with JSON.stringify(dataObject) in JS). Escaping is when every " is replaced with \". Example with " be escaped as \" then: "templateData": "{ \"paid\": true, \"invoice_id\": \"0002\", \"total\": \"$999.99\" }".

Responses

Synchronous response
An asynchronous request returns a jobId and a reserved URL that should be used only after the job succeeds. Poll it via Background Job Check. Errors return error: true with a status code and message. See the response examples and Response Codes.
Inconsistent URL Encoding in cURL Output: When using cURL to make API requests, the output JSON may show URL characters encoded as Unicode escape sequences. For example, the ampersand character (&) may appear as \u0026 in the cURL output. This is normal JSON encoding behavior and does not affect the validity of the URL. The URL will function correctly when used, as JSON parsers automatically decode these escape sequences. If you’re parsing the response programmatically, your JSON parser will handle this conversion automatically.
