Documents aren't always scanned through Acrobat but Acrobat can convert scanned documents to PDF anyway. In this video you will see how to convert a scanned document to PDF and optimize the file to clean it up and OCR the file if necessary. So I've got optimize_scan.jpeg open from the folder and when you open up a scanned document, scanned documents typically come in as images. Basically JPEGs, TIFFs. There are a lot of file formats you can utilize. If you open them directly in Acrobat, they are converted to PDF.
Based on the resolution they were, that's what they stay at. So that's kind of how they look. Now when it opens them, it opens them exactly as they were scanned. Acrobat has some tools that allow us to clean these up a bit. So they look a little bit more professional and if you look at this one out here you'd be able to see it's little bit skewed, it's kind of on an angle, the text looks little grainy, that sort of thing. So we can clean things up a bit. I'm just going to tell you, this is a great tool but it doesn't always work magic on your files. With this file open, coming up to document we will be able to see the command called Optimize Scanned PDF.
So once again, if this is something that's been scanned and you open it directly in Acrobat, click Optimize Scanned PDF. It opens up the Optimize Scanned PDF dialog box. And we have a choice up top. You've got a little Scroll bar or a Slider here to change it to smaller size or high quality. Now if you want it to look better, obviously I'm going to slide it over to High Quality, it's going to be a bigger file size. If you want it to be smaller so may be you can e-mail it or send it out somebody else, you choose smaller size. I'm going to try a little bit higher quality, make it to the right over here. Look at the options we've got down here. You've got Deskew.
This is a great thing. Deskew is going to take it and make it so that if it's an angle, it will straighten it. So it goes to about, I think it's like 15 degrees or 20 degrees, something like that. It will actually straighten it up for you. If you don't wanted to do that, may be you've got a contract and you're trying not to change its appearance, you can choose Off for that. Background removal is a great thing. A lot of scanners, if the scanner head or the glass is dirty it will put a little bit of a dark shadow on the corners. You can tell it to remove that, and if it's not aggressive enough like let's say you've got some really dark corners in this thing.
You can tell it to go with Medium background or High background. The thing about using this Optimize is there is no preview. You click OK, you try it and then if it doesn't work, you try it again. Look here you're going to see also Edge shadow removal, once again, if there is any edge shadow like there is a nice little shadow here on the very edge, it will try and remove it. Cautious means it's going not remove quite as much as it might. Aggressive is if it's really bad, it's going to try and get rid of it. And once again, for any of these settings you can turn them off if you don't want them to happen. I don't have an edge shadow so turn it to Off.
Despeckle. This can be a really important one. Despeckle says, it's dusty, it's dirty and you scan a document and it scans with a bunch of little flex and speckles all over the place. You could tell it to despeckle. Now if you like that sort of thing, you can turn it off. If you try and you don't quite think it's good enough, I usually set this pretty high to begin with because the higher you go, the more speckling it's going to get rid of all this little extra stuff out here. It doesn't always work, we will see that. Descreen. If a document has been printed and then you scan it and bring it in here, lot of times you're going to see screening.
The logo, look at GRUNBYTE right here, I will move this out of the way. You'll see the logo has a little checkerboard pattern to it. That's called Screening, so it's actually been printed and then you're trying to get rid of that. Sometimes it does pretty good job, sometimes it doesn't always do perfectly, but if you don't want it, you turn it off. I usually keep it at Automatic to handle that. And then Halo Removal. Some scanners will throw little halos around your text or your images and you probably want to get rid of that. So I will turn that on, and once you're set, you're set. You click OK, it's going to run. So click OK.
You are going to document. It will take a few seconds here. It's going to run through it, optimizing the file and there we go. Now like I said, it does a good job, sometimes it misses some things, you look out here. It's straightened the file. Things look a little bit cleaner. If you look at the logo it's not quite as checkerboard. It tried to get rid of some of that screening. If you do notice, it did miss a few of these little speckles out here. We can't get rid of those, but that's working with the document and editing the file, so we'll do that in a later video. But it did a pretty good job. Not too bad, OK. So that's working with, going through and trying to clean up a document.
By using this you're going to be able to take your documents, just give them a shine. You're going to make them look a lot better. They're not going to look like you try to scan them and then just pass them off. They'll be able to be more presentable, I guess I could say.
