JPG for photographs and scans, PNG for text, line art and anything with sharp edges. JPG artefacts are very visible around type.
A long document produces a lot of files. Extract the pages you need first if you only want a few.

Extract Images pulls out the photographs embedded within the document, at their original resolution and without the surrounding page. If you want the figure from a report, you want Extract Images.
150 DPI is fine for screens. Use 300 DPI or more if the image will be printed or re-OCR'd.
JPG for photographs and scans. PNG for text, line drawings and anything with sharp edges.

150 DPI for screen, 300 DPI or more for print or re-OCR.

These tools handle one document at a time. When the job is thousands of files, Greenbooks handles document digitization as a managed service, including bulk scanning, OCR and metadata capture, with the output loaded into DocuVenta DMS. Talk to us about volume work.
