You can upload your evidence as a JPEG, JPG, PNG, TIFF, GIF, TXT or PDF, up to 10MB in size.
If your evidence is in a Word document (DOCX or DOC) you’ll need to save a copy as a PDF before uploading.
If the evidence you have is in the body of an email, the easiest way to provide a copy is by saving it as a PDF. If you follow the options to print the email, there should be an option to save to PDF as well.
You may also take screenshots and upload those instead.
