Tips
- Signal sticker packs need a separate cover image: use a representative sticker or a unique cover design at 512x512.
- Use the Signal Sticker Creator at signal.art to upload and publish your sticker packs after preparing images in FastEdit.
- Signal supports animated stickers in APNG format, though WebP is preferred for static stickers.
