Resolve Enlarged Images in Email Signatures

Email signatures are a key part of professional communication, providing essential contact information and sometimes adding a personal touch through images and logos. However, a common issue many users face is the enlargement of images in their email signatures when viewed by recipients. This problem often arises due to the use of Rich Text Format (RTF) in emails. Here’s how to resolve this issue and ensure your email signature appears polished and professional.

Understanding Rich Text Format (RTF)

Rich Text Format (RTF) is an older file format developed by Microsoft, used primarily in Word and other Microsoft products for documents that include various text formatting options. Although versatile and widely supported, RTF can introduce complications when used in email signatures, especially with images.

Why RTF may enlarge images

When you create an email signature in an email client that uses RTF, the HTML code used to build the signature is converted to RTF. This conversion process can lead to inconsistencies, particularly with images. Text elements usually remain consistent, but images often lose their specific sizing commands and are displayed in their native size. 

Native sizes are typically larger to improve how the image is displayed, especially on high-resolution monitors. When an image is included without resizing commands, email clients using RTF display the image at its original size, which may be larger than intended for email signatures.

Options to prevent enlarged images in email signatures

• Use HTML format: Ensure you are not using RTF; use HTML format for your emails. HTML is more universally supported across different email clients and provides better control over how images and text are displayed.
• Optimize image size: Resize your images to the exact dimensions you want them to appear before embedding them in your signature. This helps ensure that the images are displayed correctly regardless of the email client's interpretation. By default, the image in your signature is 65 pixels wide. To check the image size used, go to the Images section on the Design tab.
  Keep in mind that using images at 100% scale (where the image size matches its display size) resolves the RTF image formatting issue but may result in blurry images on high-resolution screens.

• Server-side solution: By using our server-side solution, the signature is injected into the email body. This bypasses the composing stage and uses HTML formatting.

!note!Even when HTML formatting is used, there is one case when the image may revert back to being enlarged. When a recipient responds with a email client that converts his email to RTF, the image is enlarged again. Therefore the only may to 100% ensure images from being enlarged, use the Optimize image size solution.!/note!
