Attributes#

Note

Attributes are case-sensitive and should be inside JSON for POST request, for example:

{
    "url": "https://example.com/file1.pdf"
}

Attribute	Description	Required
`url`	URL to the source file. 1	yes
`httpusername`	HTTP auth user name if required to access source `url`.	no
`httppassword`	HTTP auth password if required to access source `url`.	no
`async`	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 to check the status of the process and retrieve the output while you can proceed with other tasks.	no
`pages`	Specify page indices as comma-separated values or ranges to process (e.g. `"0, 1, 2-"` or `"1, 2, 3-7"`). The first-page index is `0`, Use `"!"` before a number for inverted page numbers (e.g. `"!0"` for the last page). If not specified, the default configuration processes all `pages`. The input must be in string format.	no
`name`	File name for the generated output, the input must be in string format.	no
`expiration`	Set the expiration time for the output link in minutes (default is `60` i.e 60 minutes or 1 hour), 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.	no
`profiles`	Use this parameter to set additional configurations for fine-tuning and extra options. Explore the Profiles section for more.	no

Note

To add multiple images to convert pleaase comma-separate the url parameter. e.g. "url": "https://example.com/image1.png,https://example.com/image2.png"

Footnotes

Supports publicly accessible links from any source, including Google Drive, Dropbox, and PDF.co Built-In Files Storage. To upload files via the API, check out the File Upload section. Note: If you experience intermittent Access Denied or Too Many Requests errors, please try adding cache: to enable built-in URL caching (e.g., cache:https://example.com/file1.pdf). For data security, you have the option to encrypt output files and decrypt input files. Learn more about user-controlled data encryption.

2

Main response codes as follows:

Code	Description
`200`	Success
`400`	Bad request. Typically happens because of bad input parameters, or because the input URLs can’t be reached, possibly due to access restrictions like needing a login or password.
`401`	Unauthorized
`402`	Not enough credits
`445`	Timeout error. To process large documents or files please use asynchronous mode (set the `async` parameter to `true`) and then check status using the /job/check endpoint. If a file contains many pages then specify a page range using the `pages` parameter. The number of pages of the document can be obtained using the /pdf/info endpoint.

Note

For more see the complete list of available response codes.

PDF.co Request size: API requests do not support request sizes of more than 4 megabytes in size. Please ensure that request sizes do not exceed this limit.
