Which file types can I upload?
It is possible to upload the following file types:
- JPG (recommended)
A PDF can only be used in a portrait-oriented A4 paper size format. In the left-hand column, select 'use the PDF file as a background', click 'upload', look up the file on your computer, and open it. After a few seconds your PDF will appear. Click it and you will see a small preview. Next, click the preview and then click 'use this page'.
If you want, you can place a text block or a color block over the PDF background.
The pages will be sent to the printer in a 300 dpi/ppi quality, which translates to 2575x3600 pixels. If an image with this resolution is uploaded in Jilster as a jpg file, this image can be used to fill an entire page without loss of quality.
