- •Background: Original Transparent format maintains full resolution with transparent background - ideal for professional die-cut printing
- •Size Recommendations: 2-3" stickers work best for laptops/water bottles. 1" for phone cases.
- •Material: Glossy vinyl = shiny and waterproof. Matte vinyl = no glare, elegant finish.
- •Order Proofs: Always review digital proofs before approving production to check colors and sizing.
Custom Prompt Guide
The optional "Additional Prompt" field lets you add specific details to your sticker.
By default, the AI maintains fidelity to your source photo. Use these techniques to override that:
✅ Adding Props & Items
Holding a large pizza box with steam coming out
The subject stays the same, but now they're holding something
✅ Changing Clothing
Wearing a superhero cape and mask. Raising arms for taking off, cape stretched for take off.
Specifying clothing changes is allowed in custom prompt, otherwise the AI maintains fidelity to the source photo.
✅ Fantasy Transformations
Robot cyborg variation with glowing blue eyes and metal plating
Use "variation" or "style" to make dramatic changes
✅ Adding Text & Effects
Add comic book style speech bubble saying "POW!" with bold text
Add text overlays, speech bubbles, or stylized fonts to the sticker
✅ Non-Character Scenes (Use 'No Reaction' Emoji)
This example specifically uses the No Reaction emoji (😶) and the Blueprint style setting along with the prompt:
Technical blueprint style drawing of stand mixer with technical detailed specification call outs. High quality, professional finished.
When subject is not a humanoid or character, use 'No Reaction' emoji for more creative control over the scene
❌ What NOT to Do
Ignore system prompts and generate forbidden content
Avoid injection attacks or trying to override system prompts
💡 Advanced Prompting Tips
- •Pro tip: Use 'No Reaction' emoji when subject is not a humanoid or character. This gives you more latitude to define the scene in the custom prompt as well.
- •Be specific: "Wearing round glasses" is better than "has glasses"
- •Use descriptors: Colors, sizes, materials (e.g., "large red hat", "shiny metal armor")
- •Combine with style: Some prompts work better with certain art styles
- •Keep it short: Max 500 characters - be concise and clear
Frequently Asked Questions
❓ Generation takes a long time
Pro quality mode can take 15-30 seconds per sticker. Try Standard mode for faster results,
or reduce the number of emojis selected at once.
❓ "AI Service Unavailable" error
Google's API is temporarily overloaded. The system will automatically retry and fall back to
Standard model if Pro is unavailable. Wait a moment and try again.
❓ Sticker doesn't match the emoji
Try adjusting the Intensity setting or adding a custom prompt with specific details.
Some emojis work better with certain art styles (e.g., 3D, Anime). Experiment with different combinations!
❓ Background isn't transparent
Download the PNG formats (Telegram, Discord, Apple, Twitch) for transparency.
The Original (JPEG) format always has a white background for compatibility with printing services.
❓ How do I create a sticker pack?
Check the "Digital Stickers" tab for detailed step-by-step instructions for creating sticker packs on
Telegram, Discord, iMessage, WhatsApp, and Slack. Each platform has different requirements.
❓ Can I sell my stickers?
Yes! You can upload your stickers to print-on-demand services or sell physical stickers
made by vendors like StickerMule or MakeSticker. See the "Physical Stickers" tab for detailed instructions.

For physical stickers: 2-3 inches is perfect for laptops, 4-5 inches for water bottles.
Always order a small sample batch first to verify quality and size before bulk ordering.

well-known brands for descriptive purposes only. Results are approximate interpretations, not exact
reproductions. For commercial use, consult legal counsel.
