Signal Sticker & Image Sizes
Signal stickers are 512x512 pixels in WebP format. Unlike other platforms, Signal does not publicly list a strict file size limit, but keeping stickers under 300 KB ensures fast delivery. Signal sticker packs are created and uploaded through the Signal Sticker Creator tool. FastEdit prepares your images in the correct format instantly.
Pick this preset, drop your file, and FastEdit starts from the Signal Sticker dimensions, format, and file-size target.

- 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.
