Pngtee guides

Short how-to guides from Pngtee: each one answers a question first, then shows the steps with a real example.

• Why does my shirt design print with a white box around it?Because the file has a background. A JPG, or a PNG saved on white, prints everything in the file, box included. A transparent PNG holds only the design.
• How do I remove the white background from a t-shirt design?Upload the JPG, PNG or WebP. The box and any soft shadow are removed and nothing is redrawn. It is in beta: it works on designs with a clear outline and fails on some others.
• What size PNG do I need for a t-shirt print?Print width in inches is the pixel width divided by the print resolution. A 2048 pixel file is about 6.8 inches at 300 pixels per inch and about 13.6 inches at 150.
• Can I upload a transparent PNG to Printify, Printful or Etsy?Yes. A standard PNG with a transparent background is the artwork format print-on-demand services accept. You download it here and upload it there as your design file.
• Will my design work on a black shirt and a white shirt?Only if no important part of it is the same color as the shirt. White fills vanish on a white shirt, and black fills vanish on a black one.
