File size after OCR

Would appreciate any help with this problem.

I receive typed hard copy letters in my office, and scan them to pdf using a fujitsu. I DONT elect to OCR at that time, as some documents need it and some dont. Depending on the amount of text on these pages, they scan up at about 100kb per A4 size page. If I then take the document and run OCR within acrobat, the file size blows out considerably.

For example, I took a page of an email document today, printed to hard copy then scanned, and the file size was 62 kb. WHen I then OCR'd within Acrobat, the file size then became 645kb, it 10 times larger ! Other documents have increased from 200 kb to more than 2 MB simply by running OCR

I have no idea why this should happen, as all that is being added to the document is the resulting text reference.

Appreciate any advice please

Hi --

There are many other elements that are added to the OCR along with the text reference. For example, the OCR'ed text is actually sitting on a separate image layer, which is the principal reason the file increases in size so dramatically.

Try File >Save As and resave the file either using the existing name, which overwrites the file, or with another name. The intermediate content is flattened that way, and you'll see an appreciable decrease in the file size.donna.
