When I got my Macbook about 9 months ago one of the first things I did was change the default OSX screenshot format type from PNG to GIF. I edit a lot of images in Photoshop to post in technical articles and for the GIF’s I have been having to change the Photoshop Image Mode from Indexed Color to RGB to apply most filters during the process of editing the image. Photoshop loses a lot of functionality when an image’s Image Mode is set to Indexed so each time I modified an screenshot image and say wanted to apply a filter I would first have to modify the Photoshop Image Mode from Indexed Color to RGB. I recently got fed up with having to do that so I was looking for a solution when I realized if I just change the default screencapture format back to PNG the images open in Photoshop with the Image Mode set to RGB or Red/Green/Blue Color Model.

I was able to locate and successfully convert some jpeg files using a freeware application from CNET download center. It is very easy to use however you have to make sure your images are a certain size before converting or it will not work properly. Below are step by step instructions on how to convert multiple image files into one multi page PDF document. Make sure that each of your image files is 600×800 pixels in size or smaller if you want the entire image to fit onto the PDF page. You can also adjust the “Page Size” setting if you prefer to have larger than normal PDF pages.
