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.
