I will go into details what the "dpi" actually means, by examples; with that, you may just see the answer yourself.: In short, your image consists of dots of colour, which are next to each other. But the do not have size in any physical sense. Now, when you show an image on a screen, you will normally just put the dot colors of the image into the raster of ...

Raster images (which is what Photoshop works on) are stored as pixels. The more pixels, the larger the file size. The ppi (pixels per inch) affects how the image appears on paper. By increasing this number, the pixels get smaller when printed. However, changing this number does not affect the number of pixels. If you have a 1920 x 1080 pixel image, the ...

If you're using a set amount of pixels, let's say 500 x 500, it won't matter whether you're using 300 ppi or 72 ppi because the amount pixels in the image would still be 500. If you wan't to lower the file size of your image you will either need to scale down the image or save the image in a lower quality format: Or use Save for Web as this can give you ...

Since this is a CV, I suspect you're doing it in Word, which doesn't handle resizing of pngs very well. (I'm being overly benign saying it that way. Word's sadistic treatment of innocent raster images is worthy of a trial at The Hague.) The open source clones aren't better. Follow DA01's advice and skip the icons, or find some EPS versions (or, better yet, ...

You don't mention the software being used. When you are working in Photoshop, you are working with pixels only (aka dots). When you export to PDF, you are creating a document which is going to be printed with a presumed fixed real-world dimension (such as 8.5 x 11 inches). This is where the number of available dots comes into play, because the quality is ...

One outfit I used to work for did security borders for credit cards. These were typeset at least 10x the size of the original and reduced photographically (this was about 20 years ago). One option would be to find an outfit that still does film composition and use them. Some late model imagesetters will also go up to 5000+dpi resolutions, which might be ...
