The Pokepedia trainer card exports as a PNG image through the buttons below the card preview on /pokemon-trainer-card-maker. You can save the file, copy it to the clipboard, or reset the card.
Step 1
Click Download PNG. The browser saves a file named trainer-card-{name}.png to your default downloads folder.
Step 2
Click Copy image to put the PNG directly on your clipboard. The button text flips to Copied! for about two seconds once the copy succeeds. Paste it into any app that accepts PNG images.
Step 3
If something goes wrong, click Reset. A confirmation prompt appears, and everything on the card returns to the defaults.
