You need a software program that lets you work with graphics, such as Irfanview Irfanview is a free program and can be found at' There are two ways to reduce the jpeg file size. Examples will be based on using Irfanview. Make A PDF Smaller with Mac Preview. To make a PDF smaller on Mac, Preview should be the first solution to reduce PDF file size for mac users. As the built-in app of Apple, Preview is undoubtedly the most convenient way to make a PDF smaller on Mac, though it does not support making batch PDFs smaller at one time. Run Preview on your Mac. Most graphics programs work the same. Reduce the size of the picture (i.e. Resize 800x600 to 640x480). With.jpg picture displayed in Irfanview, click 'Image' then click 'Resize/Resample'. Increase the compression of the file. With.jpg picture displayed in Irfanview, click 'File' then click 'Save As'. Look for the 'Save Quality' slider to your right Move the 'Save Quality' slider to 50. Now change the name of the file (If the name was horse, change it to horse50). Click 'Save' button. Now use Windows Explorer to navigate to the folder where you have the 'horse.jpg' and 'horse50.jpg' Right click on each file and click 'Properties'. Compare the size of the files and you will find that 'horse50' will be smaller. If it is not small enough, go back to Irfanview and load 'horse.jpg' again and this time use a 'Save Quality' smaller that 50. Since.jpg compression is lossy, if you over-compress the picture it will effect the visual quality of the picture. Most pictures can be compressed to between 30 and 50 with little visual change. There is no absolute setting since it depends upon the complexity of the picture. A picture with a large area of blue sky will compress further). A picture with lots of surfaces, such as tree leaves, should not be compressed as much.. Joe, there is a discussion on email file sizes on the graphic's forum now. Your forum came up with a couple of other ways to resize as well as the graphic's group did. How about you compare notes and do a new post with all the suggestions needed to reduce the jpg files to fit email. Suggest that to Bob Proffitt also. You could post to both the Graphics forum as well as the Digital camera forum and inform both forums of the results. Joe, I think it would be great info for everyone. Interesting that both goups had a few more ways that are new and work for the Mac and PC. I think it is interesting to have so many ways to use photo files and manipulate them. Perhaps more ways? Thanks, and really like this forum, keep up your good work. Descargar libro la busqueda de alfonso lara castilla pdf converter free. I use the Windows Paint program. It is simple and available on most computers. Open the image with the Paint program. In the upper left hand corner click 'image.' From the next menu click the second option down, 'Stretch/Skew.' The stretch/skew option now shows Horizontal and Vertical percentages. Simply make these 50% or 25% respectively and you will immediately see the resized image. If unhappy, click 'undo' and try another size or close and 'Don't save changes.' If pleased, click File, save as, and then give it a name. Make sure that you save it as a JPEG file and not a Bit map image. JPEG will compress more unlike the Bit map file.
