About the WhatsApp Sticker Tool
WhatsApp allows sticker packs created from transparent PNG images with a distinctive white border outline. DCPIXEL automatically generates the border by dilating the alpha channel of your PNG — simply upload, adjust thickness and color, preview, and download the sticker-ready PNG.
100% Private — Processed in Your Browser
Every file stays on your device. DCPIXEL processes images entirely using the browser's built-in Canvas API and WebAssembly — zero server uploads, zero data collection.

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.
