A client has lost all electronic versions of a particular newletter he puts out. It was a 21 page B&W Word Newsletter with no photos. He needed a PDF. So I scanned each page in as a greyscale tif, opened 'em in Acrobat and let Acrobat make a 21-page PDF. It was 18mb. I used "Reduce File Size" to
reduce it" to 14mb. And that was that.

Are there any easier ways to do this?
Are there any ways to reduce the damn thing from 14mb size?
I know if this PDF was created from the original Word file, it would be a heck of a lot smaller, but none of the original electronic file exists.

This particular job is done and out the door, so there's no rush... but next time... Help?

Convert the greyscale to bitmap mode and that should help.

Did you use distiller? I find it does a better job at making the file size smaller than just doing it straight out of an app....

I dragged the tif files into Acrobat, which offered to create a 21 page PDF. Are you saying dragging it to Distiller would have been better?

You can use 'Reduce File Size' again, and again and again and again...

Each time your file will get smaller, but you'll lose some resolution/quality. How far you wish to go depends on the compromise you're willing to accept.

I've found that scanning documents directly into Acrobat (if you have a TWAIN-compatible scanner) gets you comparatively smaller file sizes.
I do not like those green links and spam.

Why don't you consider using OCR and recreating the document? It's painful, but it's most likely the only way to get the file under a 4-5 MB...

Really? My Acrobat (6) only reduces it once...

Hi,
don't think that more reduction is feasable: you're including 21 tiff's in a document (A4?) and those are taking up a lot of MB's, even when converted to jpeg's.
reducing the resolution might not help either, since it will really "erode" the text.
the OCR option might be best.
Best,
zeno

a real problem in Acrobat is the cumulative size of images in that format.
What res did you scan at? 300 dpi is not necessary for most devices.
Definitely try the Grayscale JPG solution and reduce the res to 150dpi if you haven't already
but know this 21 pages of 500KB JPGs will still be around 10MB . . .

You may be able to make them Bitmaps with a 50% threshold but I don't know if that will yield better compression on the PDF. I never tested that. It will rip apart the image quite a bit for screen viewing.
