My wife sent out an invoice, and use the 'Leafy' template. the invoice was one page, with one slip item, and 2 lines of comments. The invoice came out at 2.9 Megabytes?! I compared them to the Swiss template based ones I make, and saw that mine are usually about 20KB. I dug into the Billings app, and found that the jpeg file used in the leafy template is only 308 KB.

Either this is a bug, or I have done something else to inadvertently cause invoices with that template to be 10 times the size of the image.

Suggestions welcome!

Odd. I when spelunking through the Billings package and found the 308 KB file, and thought that what was happening was that it was being scaled up and re-saved, but the image is quite wide - 22.2 CM / 8.75" @ 300 DPI, so that isn't the case.

Is the entire PDF being saved as an image rather than text, perhaps?

The most likely cause of this is an embedded image.

In some cases, the PDF we generate does not recompress images.

Check your images - make sure they are compressed (without losing quality) or in an efficient form (vector - PDF).

If I go and copy the image in the template (from inside the template inside of billings) I get a 308Kb JPG file. If I print that image to PDF it grows by 4KB so I now have a 312KB file.

I still don't see where the extra couple of MB are coming from.
