​
Supported File Sources

Supports publicly accessible links from any source, including Google Drive, Dropbox, and PDF.co Built-In Files Storage.

The PDF.co API only accepts URLs as file inputs, not direct file uploads.

If your file is stored locally or not publicly accessible, you must upload it using the File Upload endpoints to get a publicly accessible URL.

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.

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.
