What do chat apps require from a sticker?
Each app has its own rules, and a sticker that breaks them is refused on upload or looks wrong in the chat:
| Destination | Image | Limits |
|---|---|---|
| Telegram | PNG or WebP, one side exactly 512 px | up to 512 KB each, a 100 px thumbnail, up to 120 per set |
| WebP, 512 × 512 px with an 8 px margin | up to 100 KB each, a 96 × 96 tray icon, 3 to 30 per pack | |
| iMessage | PNG, 618 × 618 px (large stickers) | up to 500 KB each |
| Discord | PNG, 320 × 320 px | up to 512 KB each |
The sticker maker prepares a download for each of these, so you do not have to resize, pad or re-compress anything yourself. Platforms change their rules from time to time; the table reflects them as checked when this guide was written.
How do I make a character pack?
Open the AI logo generator and choose Stickers, then A character.
- Describe who. For example: "a round chubby ginger cat with a cream belly and muzzle, small triangle ears and rosy cheeks, named Biscuit". This description goes into every sticker, which keeps the character recognisable.
- Pick one of four looks. The first step draws the character four ways. The one you pick is the reference for the whole pack.
- List the expressions. One per chip, with the caption in quotes:
waving "Hi!",thumbs up "OK",yawning in pyjamas "Good night". A caption can be up to 40 characters and is drawn as you type it, so check the spelling before you send. - Choose a style and a border. The style is Cartoon, Cute or Flat, plus up to 300 characters in your own words and up to three colours. The border is white, a colour or none.
Our example pack "Biscuit says…": one character, nine expressions with captions, a white die-cut border.
For a pack of objects instead of a character (snacks, plants, planets), choose Things and list them the same way. A sheet holds up to nine stickers and a pack up to 30. The price of a new pack is printed on the button before you send it.
Why is each sticker traced into a vector?
A drawing made at sheet size is too small and too soft for a 512 px sticker or a printed one. Each sticker is cut out of the sheet, traced into a vector, and given a border that the tool draws itself at an even width. The border is not part of the drawing. Because the sticker is a vector, the PNG and WebP files are rendered fresh at the size each app wants, and the print files can be any size from 3 to 10 cm without blurring.
If one sticker comes out wrong, redo it in a round with a note ("both paws visible", "caption on one line") or add new expressions; the rest of the pack stays as it is.
How do I add the pack to Telegram or WhatsApp?
Telegram: download the Telegram files and open the @Stickers bot in Telegram. Send /newpack, give the pack a name, then send each PNG or WebP as a file (not as a photo) with an emoji for it. Finish with /publish, the thumbnail and a short name for the pack's link.
WhatsApp: stickers are added through an app, not uploaded by hand. Use a sticker maker app from your phone's store, or WhatsApp's own sample project if you build your own app, and import the WebP files and the tray icon from the download. A WhatsApp pack must hold between 3 and 30 stickers.
Can I print the stickers and cut them out?
Yes. The print and cut download has each sticker as a PNG at 300 DPI and as an SVG at your chosen size. The cut line is a separate path in its own layer, named CutContour, which is the name cutting software and print shops look for. You can also ask for a whole sheet on A4 or on Letter within the Cricut Print Then Cut area. Set the bleed to 1 or 2 mm if your printer cannot print to the edge of the cut.
Cut a test sticker before printing a full sheet: printers and cutters differ in how precisely they register. The files give you a cut path; they do not calibrate your machine.
What makes a good sticker?
Use bold shapes and a clear silhouette that reads at the size of a chat bubble. Keep captions short, two or three words. Give expressions that read without the caption: a wave, a thumbs up, tears. And keep the same character description for every pack, so a second pack matches the first.
