I am making a companion banner ad for Youtube. The dimensions are 300×60. When I design on a 300×60 art board and save a a PNG or jpeg it saves with larger dimensions and then won’t upload. If i want it to be able to upload the quality is too low and it is blurry.
I need the dimensions to be 300×60, and if I resize it in another program it lowers the quality and makes it blurry.
Please help me make a crisp 300×60 image that exports less than 150 KB and is 300×60 in dimension.
Thank you!
Answer
Hit Ctrl+Alt+P and make sure your document ‘Units’ setting is set to ‘Pixels’. You may have accidentally started this document in ‘Millimeters’, in which case yes, this can be a reason for the problem.
If you are indeed working in ‘Pixels’, double check your artboard size is actually 300 by 60 pixels via Shift+O.
If everything checks out, then to properly save a PNG go to ‘File → Save for Web’, then make sure the ‘Percent’ value is ‘100%’.
