What is the Signature Converter?

Signature Converter is an AI-powered Exclaimer feature that turns a screenshot of any email signature into an editable, directory-driven template. Skip the blank canvas that comes from starting an email signature template from scratch and instead deploy consistent signatures across your organization faster.

Don't start your signature design from scratch

Choose an image

Upload a PNG or JPG screenshot of a reference image or your existing email signature, and Exclaimer rebuilds it as an editable template in seconds. No blank canvas, and no hunting for a similar template.

Tables, nested tables, spacing, and alignment take the longest to get right in any email signature. Signature Converter generates that structure automatically, so you can focus on fine-tuning the details.

Recognized personal fields, such as name, job title, and contact details, are built as dynamic fields and populated from each employee's directory profile, so every email signature stays accurate without manual edits.

Signature Converter is off by default. Admins must elect to enable the Signature Converter in Feature Settings and can turn it off at any time, ensuring admins retain full control over AI-powered functionality.

Create an email signature from an image in four steps

Upload your image

In the Signature Designer, upload a PNG or JPG screenshot of the email signature you want to recreate.

Let Exclaimer rebuild it

Frequently asked questions

What kinds of images can I upload?

PNG or JPG files up to 5 MB. A clear screenshot of the full email signature gives the best result. If an image isn't recognized as an email signature, the upload is rejected and you'll see a clear error message.

Signature Converter gives you a strong starting point that mirrors the layout of your image within Exclaimer’s signature designer. Converted signatures replicate layouts and recognize dynamic fields that pull from your directory source. However, because the template is rebuilt from an image, it is recommended to upload high-fidelity images, add hyperlinks, and review fonts and colors after conversion.

Recognized personal fields, such as name, job title, and contact details, are rebuilt as dynamic fields automatically, populating from directory data when the email signature is rendered. Text the converter can't match to a field, such as labels, website addresses, and disclaimers, are carried over from your image and can be further refined within the signature designer.
