Question

What is the optimal PDF page length to hit the PDF Extract API?

I am using the PDF extract API for one of my applications. Each PDF file page length may differ from 300 - 1000 pages. In the documentation, it is mentioned that non-scanned PDFs are limited to 200 pages and Scanned PDFs must be 100 pages or less. Limits may be lower for files with a large number of tables.

To solve the above-mentioned limitations a PDF file should be split into multiple chunks, but how can I determine the optimal no. of page length for each PDF to automate the process?

 

Questions?

What is the max no. of pages that I can hit the API with a PDF which contains only

  1. scanned pages in it? 
  2. large tables?
  3. scanned large tables? 


Thank you!

If you don't know ahead of time if the file is image only or not, I'd limit the number of pages submitted to 100 but then also pay attention to what was retuned just in case the tables are too long and it fails.

 

That said, you can use the new PDF Properties API to detect if the file contains only images and if true, send 100 at a time and if false, send 200.

Thanks for responding. I actually split my file to multiple chunks with a 50 page range length, but in one chunk there are 24 pages with scanned tables. For that chunk I am getting below mentioned error.
