The scanned image could be a TIF or BMP file, which can be quite large.
Download the FREE 'GIMP' (Graphical Image Manipulation Program), and install it.
Load the image. Crop it (to reduce size). Use 'Save As' to save as a GIF or JPG or PNG file,
which automatically compresses it.
It depends also on what you are scanning....half tones, pictures etc. but the easiest way to control the file size of PDF's is to change the resolution setting. Also referred to as the quality setting. These are settings like Super Fine, Fine, Standard. It should be right on your control panel. It is the same setting you can change when sending a fax. If your default setting is Fine for example, changing it to standard will use a lower resolution and reduce the file size. In other words the higher resolution/quality setting you use make the file size much larger.
Good Luck and Thank You for using Fixya.
The scanner produces a "picture" of the document, much as if you laid it flat on a table and took a picture of it with your digital camera. If you did this, your .jpg from the camera would be several hundred K at a minimum - comparable to the file size off the scanner. That's why the file is so big, it contains a picture and not text data - even though it's still a .jpg file. If you reduce the scan resolution you will save space, but at the expense of legibility of the document image. To get it down to the smallest possible size, you will need to run the scanned image through OCR ( Optical Character Recognition ) into a Word document for example, and then print it out to a .pdf file. If you have a clean source document with few graphics this isn't as difficult as it may seem. Microsoft Office has an excellent OCR process known as Document Imaging. You need to carefully proof read the result but with a clean input Document Imaging is amazingly accurate in Office 2007. In short, there is no easy solution to your problem.
there are different type of scannig programs. I am not that particular with your epson scanner. You can try scanning the document and if you want to archive it you can try choosig the option of file type as compressed tif. If you do not have this option there would be times that scanning software will have the preview of the document you have scanned and will asked you if you want to reduce or enlarge size. If resizing option is not available in your scanner software you can try saving it first in your computer. After saving the document try to open microsoft word and create a new file. Then look for the document you have scanned and copy that document. Once you have copied it go back to microsoft word and paste the documet. you could now resize the document manually. but for further clarification you can try calling your scanner provider. they might have some programs for it and will give it to you
I'm using an MP780. Usually when I scan an image to jpeg I press START, CANON, SCANGEAR STARTER. This open a window to ScanGear MP. Since I use the Advance Tab I can set the DPI and whatever outputs. The DPI rsolution will determine the size of the file also. When it is finished scanning it goes to the next window which has Save As Type and Save Scanned Image to. Save As Type is where you can choose JPG or TIFF or BMP. Hope this helps.
One approach that works for me is to scan the document at high resolution and then shrink it afterwards. For some reason this seems to result in higher quality than scanning at the final (lower) resolution in many cases. For example I use ACDSee Photo Manager to scan or post process a scan from elsewhere. Within ACDSee there is an option in the jpg output (file save as) dialog for quality versus compression. I set this to default to the highest compression and resave the jpg or convert to jpg if the file did not start out that way. This generally shrinks the file by up to 2x or even 4x without any degradation that I can see. For example the screen capture below went from 39k to 18k after this step with no resolution change. If that is not enough I then perform a resize operation, for example 50% which would further reduce the file size down to a quarter of the input size (the dimensions in each direction would shrink by 50%. Even after shrinking, I find that files lookbetter than if they had simply been scanned at the final resolution.
