no

lang

Set the language for OCR (text from image) to use for scanned PDF, PNG, and JPG documents input when extracting text. The default is eng. Other languages are also supported: deu, spa, chi_sim, jpn, and many others, see Language Support. You can also use 2 languages simultaneously like this: eng+deu or jpn+kor (any combination).

no

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.

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.

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.

3

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.
