An image becomes unsharp (pixelated) upon sending in Outlook on Windows

An image in your email signature can become unsharp when sending even when it still looked sharp when composing.

The cause of this issue lies in the way Outlook on Windows handles your image in combination with its dpi value.

Outlook will rescale the image as if it was a 96 dpi image. Upon sending, Outlook will convert and compress (re-render) the images to 96 dpi with the new dimensions. 

Xink doesn't change your images at all and thus doesn't change its quality.

Xink doesn't change your images at all. It will show the image in your signature in the exact same quality and with the precise number of pixels as you uploaded it in Xink.

If you notice that the quality worse after the email is sent via Outlook, that is Outlook limitation, not Xink. Outlook scales images to 96 dpi size after the email is sent in Outlook, that is why if your uploaded images don't meet this requirement, you can be affected with the blurry image on the recipient side.

Re-render the image at 96 dpi

The quickest and easiest way around this issue is to re-render your images at 96 dpi. 

In general, this will not produce a noticeable quality loss.

Right-click the image file and verify it's 96 dpi. 

Select Properties and Details tab:

Using Photoshop

When using Photoshop, make sure to check:

  • Resample is set to 'Preserved Details' (default is 'Automatic') 
  • Reduce Noise is set to 100%.

Still an issue?

If JPG format shows the issue, try and change to PNG format (shows good results with background colors). If PNG format shows the issue, try and change to JPG.
