Recover Email Signature Date with airSlate SignNow

Install signature resolution

hi my name is Gordon from gimme OH and today I'm going to show you how to fix email signature images that are changing size but so what I mean by that is sometimes when you create an email signature and you expect an image to be a certain size when you paste it into your email client such as our law court Apple Mail the image itself actually becomes a lot bigger so it becomes enlarged the reason that happens is because Outlook and Apple Mail they use dpi which is dots per inch in order to scale the images or more so to display the images on in the inside the email client so if your images are over 96 dpi for Outlook or over 72 dpi for Apple Mail the images would look larger when they're actually displayed in the email client itself so just to give you a bit of background about dpi DPI's dots per inch and what that means is if you've got an inch you know worth of screen space it's the amount of dots or pixels that will be that will populate that one inch of length so yeah so just recapping back to what we said earlier outlook likes images which 96 dpi and app mail likes images which is 72 dpi so just keep that in mind if you're using Apple Mail or Outlook you can apply those different dpi settings to your images so the next thing I will talk about is how you actually have a look at what your images are in terms of dpi so you'll notice we've got two images here one is the JPEG and one's a PNG in Windows by default you can actually find out what the dpi value is of jpg or JPG images quite easily and I'll show you how to do that now you just right click on it and go to properties and then go to details and you'll be able to see here the vertical resolution and the horizontal resolution of both 72 dpi so for this instance this image will work fine for a wild man it won't get blown up to be in like a larger size or anything like that so next we've got a PNG image and I'll show you the same thing if you go to properties you'll notice in PNG image it doesn't actually show the DPI and value here anywhere and that's just something that Windows does it doesn't actually show you the DPI value of PNG images I'm not sure why but it is just the way it is but yeah so what you can do instead is you can actually look at dpi or value of an image inside you know a really good image editing software such as Photoshop so I'll show you how to do that now is you just right-click on it and then open with Photoshop so we've opened that image out now and...
