About the Sticker Maker Tool
Creating stickers for WhatsApp, Telegram, iMessage, or print projects requires adding a clean white border around the subject of a transparent PNG. DCPIXEL's sticker border generator uses morphological dilation to grow the image outline — giving you a professional sticker look without Photoshop.

Frequently Asked Questions
Do I need to remove the background first?+
Yes, for the best sticker effect. Start with a PNG that has a transparent background, then our tool adds the thick outline border to create a perfect sticker look.
Can I use any color for the sticker border?+
Yes. While white is the classic sticker outline, you can choose any color using the color picker — black, gold, neon green, or any custom color.
What thickness can the sticker border be?+
The thickness slider ranges from 1px to 50px. For WhatsApp and Telegram stickers, 10-20px typically looks best at the display size.
Can I use this for WhatsApp and Telegram stickers?+
Yes. Export at 512x512px (required by both platforms) with a transparent background and white outline. The result is ready to import into your sticker pack.
