An AI Christmas card generator takes a photo you already have, or a few lines of description, and gives back a finished card image with the greeting on it. In Toybox AI, Smart Editor edits your family photo from a typed instruction, Flyer Maker designs a card with no photo, and AI Writer drafts the message inside. Below are five prompts, a table of card wording, the pixel sizes that fill a 5 x 7 in card, and the USPS postage and mailing date.
What you can make with an AI Christmas card maker
An AI Christmas card maker helps most when you already have the photo and only need the card around it:
- A photo card from last month's picture. Upload the pumpkin patch photo and ask for a thin red border, pine sprigs in the corners, and "Merry Christmas from the Kowalczyks" along the bottom.
- A winter setting behind the same people. Swap a gray driveway for a snowy porch with string lights, and keep the faces, sweaters and poses as they are.
- A pet card. A red scarf on the dog, a wreath on the door behind him, and his name on a wooden sign.
- A design-only card. No photo: a watercolor wreath, the greeting and the family name, made in Flyer Maker from a description.
- A card for clients. A staff photo with a garland along the top and "Happy Holidays from Our Team to Yours", or an illustrated card with your logo.
- The message inside. A short note for neighbors, clients or the grandparents, drafted in AI Writer and rewritten by you.
If the card also invites people to your party, the Christmas party flyer wording covers the RSVP line and the ugly sweater contest, and the AI invitation maker covers invitations you print or text.
Three ways to use an AI Christmas card generator
To create a holiday card with AI in Toybox, pick the tool by what the front of the card shows. Credit costs below are September 2026 figures and can change; plan prices are on the pricing page.
| Card type | Tool | Input | Plan and cost | Use it for |
|---|---|---|---|---|
| Photo card | Smart Editor | One JPG or PNG up to 10 MB, plus an instruction | Pro plan; 85 credits HD, 110 credits 4K | Your real family, couple or pet photo with a frame and greeting |
| Design-only card | Flyer Maker | A description of up to 3,000 characters, plus an optional logo | Free plan; 80 credits, 90 for 2K, 100 for 4K | Illustrated cards and client cards with no people |
| Card message | AI Writer | A brief of up to 2,000 characters | Free plan; 5 credits | The note inside, or the caption when you post the card |
For a design-only card, type every word that should appear. Flyer Maker is built for flyers, and when a line is missing it fills the space with a tagline of its own. A description with every word spelled out: "Christmas card, no photo. A loose watercolor wreath of pine, holly and red berries on cream paper. In the center, 'Merry Christmas' in dark green script, and below it 'Love, the Kowalczyk Family' in small serif letters. No other text." Choose Tall (3:4) for a portrait 5 x 7 in card, at 2K or 4K. For a landscape card, Wide (5:4) at 4K works, but it loses about 0.6 in off the height on a 7 x 5 in print.
AI Christmas card prompts for your own photo
Each AI Christmas card prompt below goes into Smart Editor's "What should change?" box after you upload your photo. Smart Editor runs on OpenAI's GPT Image 2.5, and OpenAI's prompting guide gives three habits for exact text: put the words in quotation marks, spell unusual names letter by letter, and say how many times the text should appear. Every prompt here quotes its text and says how often it appears, and the ones with a surname or a made-up word spell it out.
Classic red border and greeting
Make this photo the front of a Christmas card. Add a thin deep red border with small pine sprigs and red berries in the four corners. Write "Merry Christmas from the Kowalczyks" once, centered along the bottom edge in white serif letters, spelled K-O-W-A-L-C-Z-Y-K-S. Keep every face, hairstyle, expression and outfit exactly the same, and change nothing else in the photo.Snowy porch behind the family
Replace the background with a snowy front porch at dusk, white string lights wound around the porch posts and a wreath hung on the door. Light our faces with the warm glow of the porch lights. Write "Season's Greetings" once in white script along the top edge. Keep all five people, their faces, poses and sweaters exactly as they are.Kraft paper card with photo corners
Make this photo look like a print mounted on a kraft paper Christmas card, with white photo corners, a sprig of dried eucalyptus and a small twine bow beside it. Show the card lying flat under soft, even light so the paper grain shows. Under the photo, write "Joy to the World" once in simple black handwriting. Keep the photo itself and every face in it unchanged.Pet card
Put a red knit scarf on the dog and replace the background with a snowy doorstep and a pine wreath on a green door. Add a small wooden sign by the door that reads "Happy Howlidays from Biscuit", spelled H-O-W-L-I-D-A-Y-S, shown once. Keep the dog's face, fur color, markings and pose exactly the same.Team photo for clients
Add a garland of pine branches and small white lights along the top edge of this team photo, and a light snowfall over the background only. Write "Happy Holidays from Our Team to Yours" once across the bottom in navy letters on a cream band. Keep every person's face, expression and clothing exactly the same.More AI Christmas card ideas that start from one photo: a black and white photo with only the red scarves left in color, a frosted window frame around the family, or a plain cream background with the top third left empty for a greeting you set in a card editor. For a new setting before the card step, such as a fireplace or matching pajamas, use the Christmas AI photo prompts.
Christmas card wording you can copy
Keep the front short and put the personal part inside. Give any AI Christmas card message generator, AI Writer included, one real detail from your year in the brief, so the draft has something specific to say. With Type on "Anything" and Length on "Medium" (Short tends to return only a few sentences), a brief could read: "Write three short Christmas card messages from the Kowalczyk family to our new neighbors. They helped us carry the couch in during the June move. Warm and a little funny, under 40 words each." AI Writer has no tone setting, so the tone goes in the brief.
| Card | Front greeting | Inside message |
|---|---|---|
| Family photo card | "Merry Christmas from the Kowalczyks" | "Wishing you a slow, warm December. Love, Anna, Marek, Zosia and Leo" |
| First Christmas married | "Our First Christmas as the Parks" | "Thank you for being part of our wedding year." |
| New baby | "Merry Christmas from the Three of Us" | "Meet Theo, born August 30. He already has opinions about naps." |
| Not religious | "Season's Greetings" | "Peace, rest and good company this season." |
| Faith-based | "Joy to the World" | "Wishing you the peace of Christmas. Luke 2:14" |
| Pet card | "Happy Howlidays" | "Biscuit wishes you long walks and dropped crumbs." |
| Clients or customers | "Happy Holidays from Our Team to Yours" | "Thank you for a good year. Our office is closed December 24 to January 1." |
| Late card | "Happy New Year" | "Our cards are late. Our love for you is on time." |
Tips for photo cards that print well
Start with a photo that has room around the people. A border and a greeting need space. If heads touch the top edge, the text can land on someone's hair, or the edit can shrink the family to fit.
Spell the surname in the prompt. Kowalczyk, Nguyen-Hart or O'Donnell are easy to get wrong. Write the name in quotes, then again letter by letter, and read it on the result one letter at a time.
Add the setting and the text in separate edits. Change the background first and check the faces, then add the greeting on the latest result. OpenAI's guide recommends one change per edit while repeating what must stay. Separate edits also show you which instruction caused a problem.
Name the paper for a card that looks photographed. In its holiday card section, OpenAI's guide suggests describing the paper's layers, fibers and folds, and soft studio light. That is why the kraft paper prompt asks for photo corners, twine and visible grain.
Decide the shape first. "Original" keeps your phone photo's proportions, which trim to 5 x 7 in by losing about 1/4 in off the width. Square suits a 5 x 5 in card. With a new shape, the AI refits the whole scene to it, so check the edges for anyone squeezed or cut off.
Christmas card sizes, printing and mailing
A 5 x 7 in card needs 1500 x 2100 pixels at 300 pixels per inch, according to Nations Photo Lab's resolution chart, and a 4 x 6 in print needs 1200 x 1800. Toybox saves PNG files with no bleed, so ask your print service how much it trims from the edges and keep the greeting away from them.
| Card | Pixels at 300 PPI | Toybox setting and output | Trim and postage |
|---|---|---|---|
| 5 x 7 in portrait | 1500 x 2100 | Smart Editor 4K, Original, upright photo (2480 x 3312); or Flyer Maker Tall 3:4 at 2K (1536 x 2048) or 4K | About 1/4 in off the width; 82-cent letter |
| 7 x 5 in landscape, photo | 2100 x 1500 | Smart Editor 4K, Original, sideways photo (3312 x 2480) | About 1/4 in off the height; 82-cent letter |
| 7 x 5 in landscape, no photo | 2100 x 1500 | Flyer Maker Wide 5:4 at 4K (3200 x 2560) | About 0.6 in off the height; 82-cent letter |
| 4 x 6 in photo postcard | 1200 x 1800 | Smart Editor 4K, Original, upright photo | About 1/2 in off the width; 65-cent postcard |
| 5 x 5 in square | 1500 x 1500 | Smart Editor 4K, Square (2880 x 2880) | No trim; 82 cents plus a 49-cent surcharge |
At HD, the same upright photo comes back at 1024 x 1360 pixels, about 194 pixels per inch on a 5 x 7 in card. Nations Photo Lab says files at 125 PPI or higher print well on its printers, so HD can work at that lab, but 4K is the only Smart Editor setting that meets the 300 PPI column.
USPS rules that decide when and how cheaply a card arrives, as of September 2026:
- Mail by Thursday, December 17. It's the USPS recommended First-Class Mail date for expected delivery before December 25 in 2026, for the lower 48 states and for Alaska and Hawaii.
- A standard card mails at the letter price. A stamped letter up to 1 oz costs 82 cents under the price list effective July 12, 2026, and a 2 oz letter costs $1.11.
- Square envelopes pay extra. A letter whose length is less than 1.3 times its height is nonmachinable under USPS rules, which adds a 49-cent surcharge. A 7.25 x 5.25 in envelope for a 5 x 7 in card has a ratio of about 1.38, so its shape alone doesn't trigger the surcharge.
- Postcards cost less. A card at least 3.5 x 5 in, no larger than 4.25 x 6 in, and no thicker than 0.016 in mails at the 65-cent postcard price.
Limits to know
Any holiday card AI generator, Toybox included, can misspell a surname or blur a small line of text. Read every letter at full size before you order 60 prints.
- Photo cards need Pro. On the Free plan, with enough credits, you can still make a design-only card in Flyer Maker and write the message in AI Writer. Flyer Maker's "Add your logo" upload is for a logo, not a family photo.
- Smart Editor redraws the whole photo on every edit. It can't lock one area, so a face, a hand or a sweater pattern can shift. If someone looks different, switch "Editing" back to "Original photo" and ask for less at once. When faces must stay pixel for pixel, OpenAI's guide says to composite the edit onto the original: set the greeting over your untouched photo in a template card editor instead.
- One photo per edit. Smart Editor can't merge two pictures. For relatives who were never in the same shot, the family Christmas photo guide covers adding them one at a time, and the AI Santa photo steps cover putting Santa in your living room.
- Flyer Maker text can come out wrong or padded. Type the fix into "Want to change something?" under the card, currently 60 credits (70 for 2K, 90 for 4K), or correct the description and make a new card.
How to make a photo Christmas card in Smart Editor
- On a Pro plan, open Smart Editor and upload the card photo under "Your image". It takes JPG and PNG files up to 10 MB; if your iPhone saved a HEIC file, export a JPG copy first.
- Open "More options" and set "Quality" to 4K for printed cards (currently 110 credits) or HD for cards you text (85 credits). Leave "Shape" on "Original" for a 5 x 7 in card.
- Type the instruction in "What should change?": the frame or setting, the greeting in quotes, the surname spelled out, and "keep every face exactly the same".
- Tap "Apply edit". An edit usually takes about 30 seconds.
- Proof it at full size. Read the greeting letter by letter and compare each face with your original. Fix a misspelled name with a short follow-up on the latest result, such as "change the name to Kowalczyks, spelled K-O-W-A-L-C-Z-Y-K-S".
- Download the PNG for your print service, or save it to your gallery. If an edit fails, your credits go back automatically.
Pro currently costs $9.99 a month for 1,000 credits, enough for 11 HD edits with some left over. Photos of your kids are personal, and the Toybox privacy policy says prompts, uploads and results aren't used to train AI models.
