Projector automatically scales some receipt types for display on invoices. This scaling prevents the generated PDF from becoming too large. Large PDFs take longer to generate, longer to download, and may be too big for emailing.
When you render an invoice, all receipts are converted to grayscale. If the converted file is greater than 500kb we shrink it 500kb in size. At this time, PDF and PNG are not subject to these file size reduction methods.
