We are using pdf files as an input and "pdfSearchable" as an output format. Is it possible to control image compression in the output PDF file? Now we get images recompressed into JBIG2, and they visually look worse than original ones. Another point is that some libraries, we use for further processing (pdflib, pdfbox), doesn't have a support for JBIG2. Does any parameter exist to keep the original image unchanged?

Dear Josef, thank you for your question! Now this feature is available in offline SDK only. We will consult with our analyst if it could be added to Cloud OCR SDK and will inform you as soon as we will have additional information.

Could you please clarify, do I understand correctly that to save original images in a good jpeg quality is suitable for your task (you do not need to save it absolutely unchanged without any recompression)?

yes, it's suitable for our purposes

PDF export parameters will be extended, but not in the nearest months (after the technologies update only). If you have any more suggestions about how to improve PDF export API, please let us know.
