Postcard templates and editing
The editor opens with a postcard template, and the gallery includes more postcard and greeting card designs, including Christmas cards. Every part is editable:
- Photo: drop in a JPG, PNG, WebP, AVIF or iPhone HEIC photo. Crop, pan and zoom it inside the frame, or place it in a circle, arch or polaroid frame. Filters such as vintage, warm, fade and black and white give a travel photo a classic postcard feel.
- Text: a big greeting like Greetings from Lake Tahoe, in any of 40+ free fonts, with outline, shadow, highlight background or curved text.
- Decorations: recolorable stickers, shapes, lines and patterned backgrounds.
Several photos? Use a collage layout on the front, with one large photo and smaller ones around it.
Postcard sizes
| Size | Inches | Metric | Use |
|---|---|---|---|
| Postcard, landscape | 6 × 4 | 152 × 102 mm | Standard US postcard |
| Card, portrait | 4 × 6 | 102 × 152 mm | Same, upright |
| Greeting card | 5 × 7 | 127 × 178 mm | Larger card, mailed in an envelope |
| A6 postcard | 5.8 × 4.1 | 148 × 105 mm | Standard outside the US |
| Square card | 5.8 × 5.8 | 148 × 148 mm | Modern look, in an envelope |
| Digital | 1080 × 1350 px or 1200 × 630 px | Instagram, email, messaging |
Switch sizes and the layout adapts automatically. Print sizes include a 3 mm (about 1/8 in) bleed, and the editor shows the trim line and safe zone. Keep text inside the safe zone so nothing is cut off.
Designing the back
To make the back, start a second design in the same size. A classic US postcard back has a vertical line down the middle: the left half for your message, the right half for the address and stamp. Draw the line with the line tool, add a short caption at the top left, such as the place and date (Lake Tahoe, 07/18/2026), and leave the right half blank. Mail requires a clear address area, so do not put a background photo or pattern behind it.
Many people simply print the front and write on the plain back of photo paper or card stock by hand; that works too.
Printing and mailing
Print shop or online printer: download the PDF. It is 300 dpi with bleed and crop marks.
Photo lab: switch to the 4 × 6 in photo print size, which matches photo paper exactly with no bleed, and download a JPG.
At home: print on 4 × 6 photo paper or card stock; borderless printing gives the cleanest edge if your printer supports it.
To mail at the US postcard rate, a card must fall within the Postal Service's postcard limits: up to 4.25 × 6 in and within a minimum and maximum thickness. A standard 4 × 6 in card on postcard-weight stock qualifies; a 5 × 7 in card mails as a letter in an envelope. Check the current USPS rules before printing a large batch.

Privacy
Your photo stays on your device: it is opened, edited and exported in the browser and never uploaded. There is no watermark and no sign-up, and the editor works with touch on phones, so you can make a postcard from a photo you just took.
Phone photos are usually sharp enough for a 4 × 6 in print. Avoid screenshots and images saved from messaging apps, which are often compressed and can look soft on paper. If your photo is too dark, the brightness and contrast sliders fix most problems; a warm filter helps beach and sunset shots, and black and white rescues a photo with mixed lighting. Save the project file if you want to send the same postcard design again next trip with a new photo.
Frequently asked questions
What size is a standard postcard?
4 × 6 inches is the most common postcard size in the US. Outside the US, A6 (148 × 105 mm) is common.
Can I make the back of the postcard?
Yes. Start a second design in the same size, draw a dividing line and leave the right half clear for the address and stamp.
Can I mail a 5 × 7 card as a postcard?
No. The US postcard rate covers cards up to 4.25 × 6 in. A 5 × 7 card mails as a letter in an envelope.
Can I print the postcard at home?
Yes. Print on 4 × 6 photo paper or card stock, or print the PDF at actual size and trim along the crop marks.
Can I use iPhone HEIC photos?
Yes. HEIC, JPG, PNG, WebP and AVIF all open directly.
Is my photo uploaded?
No. Everything happens in your browser.
