Free postcard maker with a real back
This makes a two-page PDF: page one is the postcard fronts, page two the backs. Two postcards fit on a Letter sheet at 4 × 6 or 5 × 7 — four-up would need a card smaller than 4×6, which doesn't fit Letter. The front takes a photo or a centered message; the back is laid out the standard way, with a stamp box in the top-right corner, ruled address lines, a message area, and a divider down the middle.
Sans type keeps the file tiny; the serif option embeds a font and adds about 220 KB when you want a more formal look.
Using the tool
Add a front photo, or type a front message to use when there's no photo. Pick the size and typeface. The preview shows the fronts on page one and the backs on page two. Click Download PDF.
Printing double-sided
- Print at 100% scale on cardstock.
In the print dialog — the window that opens when you choose Print — set Scale to 100%. Postcards need card weight, not paper. - Print double-sided so the back lands behind the front.
Turn on double-sided (duplex) printing and flip on the long edge. - Cut between the two cards.
A paper trimmer gives a clean postcard edge.
FAQ
Do I need an account?
No. There is no signup and no login — open the page and use it.
Can it print four to a page?
Not at these sizes. Two 4×6 or 5×7 cards fill a Letter sheet; a four-up layout would need a smaller card.
Does my data leave my browser?
No. The postcard is built locally in your browser and nothing is uploaded. Once the page has loaded you can work offline.
