Hi I'm new to Photoshop. I've created a .psd file which I'm going to save as a PDF in A4 size. However, I now want to change it to make it A5 size when it is converted to a PDF. Is there a quick way to do this please or do I have to start again or select all of the items on the document (in each of the layers) and resize?
Thanks for your help!
A5 is exactly half the size of A4, so if you open Image resize (Ctrl Alt i or Cmd Opt i) and uncheck resample, and double the resolution, you are there. For instance if the resolution is 300dpi, and you change it to 600 dpi, it will print at A5. If you want to reduce the file size, check Resample, and make the dpi 300 again. It works like magic.
Great, thank you so much Trevor, I will give that a try!
