Stickers help you react in chat without typing a full message. You do not need to be an artist to make a set. With an AI image tool and a simple plan, one character can become a matching pack of expressions.
The key is to keep the project small. Pick one character and one style. Then change only the expression or pose from image to image.
Step 1: Choose one character and one style
Start with a character you can describe in a few words, such as a round cat, a friendly robot, or toast with a face. Keep it simple. Too much detail disappears when the image is small.
For the style, try flat cartoon with thick outlines. It reads well at small sizes, stays consistent, and makes background removal cleaner.
Step 2: Write a base prompt
A base prompt is the main description you reuse. Write it once, then change only the expression or pose. Here is a simple example:
Flat cartoon character with thick black outlines, a round friendly face, simple shapes, solid colors, plain white background, full body, centered, no text.
Replace the character description with your subject, but keep the style words the same. Save it for reuse.
Step 3: Change only the expression or pose
Make your first four stickers with the same base prompt, adding one short line for each.
- Happy: smiling with raised eyebrows.
- Thumbs up: one hand giving a thumbs up and a big smile.
- Sleepy: half-closed eyes, a small yawn, and a tilted head.
- Surprised: wide eyes, an open mouth, and hands near the cheeks.
Do not rewrite the whole prompt. Changing style, lighting, or character details too will make the images drift apart.
Step 4: Keep the background plain
Ask for a plain white or solid light background. A clean edge is easier to cut out. Avoid shadows, scenery, props, and busy patterns. Keep the character away from the edges, with space around the head and hands.
Step 5: Remove the background
Use a background remover that saves a transparent PNG. Zoom in and check the edges around hair, fingers, and thin lines. If you see a white fringe, try a cleaner source image or run the removal again. Transparent stickers look good on light and dark chat themes.
Step 6: Process the whole set in one go
A batch background remover processes a whole set at once. This saves time and gives every sticker the same treatment. Name files clearly, such as happy, thumbs-up, sleepy, and surprised.
Step 7: Keep size and style consistent
Use the same canvas size and character scale for every sticker. If one is much larger or smaller, the pack will look uneven.
If you plan to make many stickers, custom LoRA styling can help keep one look across a set. The same reference image and style words also help. Consistency matters more than variety here.
One example is NewYouGo, which covers prompt-based image creation, background removal, batch background removal, and custom LoRA styling. Compare a few tools and use what fits your workflow.
Step 8: Check readability at small size
Stickers often appear small. Shrink each image to chat size and look at it on your phone. Simplify anything that turns into a blur. Strong outlines, clear shapes, and high contrast help. The expression should read at a glance, without text.
Step 9: Match your chat app's rules
Each chat app has its own sticker size and format rules. Check the app's help page or upload guide before you export. You may need a specific pixel size, file type, file size limit, or number of stickers per pack. Some apps also ask for a cover image. Follow the rules exactly, or the upload may fail. Keep your large originals so you can resize again later.
Step 10: Use only characters you have the right to use
Only use characters you have the right to use: your own original character, one you commissioned with permission, or a subject you are allowed to adapt. Do not copy a famous cartoon, game character, mascot, or someone else's art without permission. If you use a photo of a real person, get consent. Note where your reference images came from.
A simple workflow to try
Make the four starter stickers first: happy, thumbs up, sleepy, and surprised. Generate them from the same base prompt. Remove backgrounds in one batch. Resize to your chat app's rules. Test at small size on your phone. When the first four look like one family, make more. Add poses only after the set is clean and consistent.
