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.
Free — No Account, No Limits
DCPIXEL is completely free with no daily limits, no watermarks, and no registration. We never process your files on our servers, so we can offer this permanently at no cost.
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.
