Hello team,

Hi @Kajal8 

Yes, it is possible to convert a Base64 encoded image to a PNG image using a script in ServiceNow. You can do this by using the GlideSystem class in ServiceNow to create a new Attachment record, and then decoding the Base64 encoded image data and writing it to the newly created Attachment.

Here is an example of how you can convert a Base64 encoded image to a PNG image using a script in ServiceNow:

// Decode the Base64 encoded image data
var imageData = new GlideString(base64EncodedImage);
var binaryData = GlideEncryption.decode(imageData);

// Create a new Attachment record
var attachment = new GlideRecord('sys_attachment');
attachment.initialize();
attachment.setValue('table_name', 'YOUR_TABLE_NAME');
attachment.setValue('table_sys_id', 'YOUR_TABLE_SYS_ID');
attachment.setValue('file_name', 'image.png');
attachment.setValue('content_type', 'image/png');
attachment.setValue('data', binaryData);
attachment.insert();

Keep in mind that, if the image is not a PNG image, you should change the 'content_type' and the 'file_name' properties accordingly.

I tried to run this but it is giving error message "GlideString is not defined".
