iMessage Sticker Sizes & Presets
iMessage stickers come in three size classes: Small (300x300), Medium (408x408), and Large (618x618), defined by Apple for the Messages app. Each sticker in a pack must use the same size class. FastEdit helps you resize and export images at the exact dimensions Apple requires so your stickers render perfectly on every device.
Pick this preset, drop your file, and FastEdit starts from the iMessage Sticker Small dimensions, format, and file-size target.
