WhatsApp Sticker ResourcesThe technical rules behind WhatsApp stickers

Sizes, formats, animation limits and pack metadata — in one place, with copy-paste conversion commands.

Sticker requirements

Pre-publish checklist

Exact specs

512 × 512 WebP, per-file size limits, tray icon rules and pack size — with the reasoning behind each limit.

Animated stickers

Frame timing, duration, the 500 KB budget and why the first frame matters more than the last.

Conversion recipes

Tested cwebp and gif2webp commands, plus ffmpeg and ImageMagick pipelines for padding and resizing.

Pack metadata

A field-by-field reference for contents.json — identifiers, emoji tags, accessibility text and versioning.
