Are your email signature images changing the size or showing much larger when you install the signature in your email client?
To display the images in your email signature correctly, you must use the following DPI settings depending on your email client.
If you're using Microsoft Outlook, the DPI of the image should be 96 DPI.
If you're using Apple Mail, the image should have 72 DPI.
If you have an image in your signature with a DPI of 300, it will look very big. This happens because Microsoft Outlook and Apple Mail scale images using the DPI value.
To fix this, you will need to use an image processing tool such as Photoshop to change the image's DPI setting.
How to check the DPI of your images
The simplest way to check the DPI of an image in Windows is to right-click on the image > Properties > Details tab and check the DPI value.
Note: This method only works on some image types and will not work on PNG images.
You can also check and change the DPI of an image using almost any image processing software, such as Photoshop.
How to change the DPI of your images using Photoshop
Step 1. Open your image in Photoshop.
Step 2. Click on image > Image Size.
Step 3. In the Resolution field, enter the new DPI value you want to use (96 DPI for Outlook or 72 DPI for Apple Mail) and ensure that the measurement is set to "Pixels/Inch".
Also, please make sure that Resample: Automatic is ticked.
Step 4. Save your image and use it in your email signature.
Now that the DPI has been changed, this should stop it from scaling up in size.
