Question

Hello,
I need to scan and attach certificates to visa application. How do do this, they are currently to big.

Must be something I can do myself. eg with my scanner or using pdf or something similar.

Answer 1

What you want to do is look at the scan composition and the output file format. If the document is black & white, try going with a TIFF type 4 (the type of format used by fax machines) to greatly reduce the file size. If the document contains color or gray scales, jpeg can be fairly small if you can control the file resolution (dpi). As for applications to do this, I've used ImageAlchemy (at work) from Handmade Software in the past but it isn't a free application. Adobe Photoshop should be able to do what you want as well, but again, not a free application. You could give GIMP, a free open source image manipulation program, a shot.

** Edit **
simonjohnlaw - Often image formats already are optimally compressed so that zipping the output zipped file will actually be larger than the input (due to the overhead of the compression). Still worth a shot, but I generally don't expect a decrease in file size.

I think the best thing to do would be to use a simple scanner and scan it into PDF. In Adobe Acrobat Standard or Professional there is a save function to reduce file size. This usually shrinks the file size to a fairly small size. It is an image compression issue.

If you scan it as an image, you also have an image compression, # of bits problem. However, using a cool program like Adobe Photoshop Elements, there is an option to save the image as a web image, which similarly can shrink the image.

Also, if you scan in color, that takes up a lot more space than a black and white or a grayscale scan.

Answer 3

What are the formats you scan to ?
The graphics guys we have in the programming sections use Raster Graphics, mostly either ULead or LEAD 14 or 15, and this will change the Format size to 100kb, and retain the Resolution.
Are you expected to have full colour Graphics ? A jpg file will take almost any BMP or similar file an take it right down.

Answer 4

convert the file into JPG then size will down.................

Answer 5

you can change their format

Answer 6

* use winzip or zip7 it free
