Which file type is best for me?
PNG files are ideal for this. They can be used in the same way as a JPEG but are transparent so can also work on different coloured backgrounds. They are smaller files and load quickly.
The PNG’s are supplied large so you may opt to shrink these, though most social media services will do this for you.
If you are preparing artwork for print use the vector and PSD (Photoshop format) files.
