Image format, dimensions, file size, metadata, tray icons, emoji associations, and validation all play a role in preparing a sticker pack.

This guide explains the main technical concepts developers and sticker creators should understand before publishing a WhatsApp sticker pack.

1. What Is a WhatsApp Sticker Pack?

A WhatsApp sticker pack is a collection of stickers grouped together so users can install and use them from WhatsApp.

A typical sticker pack involves:

  • Sticker images

  • A tray icon

  • Pack metadata

  • Emoji associations

  • Information required by the sticker application

A consistent structure makes the pack easier to validate, publish, and maintain.

2. Sticker Image Format

WebP is commonly used for WhatsApp sticker artwork because it can provide good image quality while keeping files relatively small.

When preparing sticker images, pay attention to:

  • Image dimensions

  • File size

  • Transparency

  • Image quality

  • Compression

  • Static or animated content

For example, a PNG image can be converted to WebP using cwebp:

cwebp -q 80 sticker.png -o sticker.webp
