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
200Success
400Bad 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.
401Unauthorized
402Not enough credits
445Timeout error. To process large documents or files please use asynchronous mode (set the
asyncparameter totrue) and then check status using the /job/check endpoint. If a file contains many pages then specify a page range using thepagesparameter. 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
4megabytes in size. Please ensure that request sizes do not exceed this limit.
