Stickers in Signal were announced together with the introduction of the first two official sticker packs: Zozo the French Bulldog by Arrow Bowie, and Bandit the Cat by Agnes Lee.

• Stickers can be a collection of animated or static images.
• Stickers have a size limitation of 300kb with a resolution of 512 x 512px and a maximum of 200 stickers per pack.
• Stickers are sent as encrypted attachments or are shared via a custom URL containing a pack_id and pack_key which allow anyone to download the sticker pack.

Getting sticker packs

Official sticker packs

Signal has created official sticker packs available for download from within the application.

Unofficial sticker pack sources

Signal Stickers is the largest unofficial directory for Signal sticker packs. It contains more than 5000+ sticker packs, and gives users a searchable interface with different categories. Users can contribute sticker packs to be indexed and the website includes stickers ported from Telegram by the @signal-stickers GitHub account.

Creating sticker packs

Development & internal details

Development history

Future
This article or section describes a concept currently in development or in beta.
Behavior may change significantly before release.

• 2019-12-17: Signal Desktop adds support for creating stickers. This old sticker creator is built-in and only accessible within the Signal Desktop app (and only after you've linked Signal Desktop to your primary device).
• 2022-12-19: Development of the new sticker pack creator, Art Creator, begins.
• 2023-02-28: The menu item that opened the old sticker creator in Signal Desktop now opens the Art Creator instead, providing the necessary authentication details so that the user is immediately signed in.
• 2023-04-20: Signal Desktop switches back to a "built-in sticker creator" approach, packaging a copy of the Art Creator in itself. The Art Creator is still separately available at create.signal.art (there's also a corresponding version for staging builds of the app at create.staging.signal.art), however.

Signal Sticker Pack Creator (Art Creator)

Because there seems to be a separate rate limit for artPacks in addition to the existing one for sticker packs (and other references to "art pack"), it is possible that the Art Creator may be used to create not only stickers, but other similar forms of content in the future.

Authentication

The prompt that appears in Signal Desktop when trying to sign in to the Art Creator.

Using Signal Desktop, you can press on a menu item to go to the Art Creator, which will automatically add authentication credentials to the opened URL so that you are immediately logged in.

Otherwise, you can open the Art Creator yourself and press on the sign-in button, which will open Signal Desktop (potentially other platforms will support authenticating for this service too in the future?) and a prompt will appear in Signal Desktop that allows you to sign in to the Art Creator.

Authentication credentials are generated by the server (Signal Desktop requests it do so). The server code has been added on 2022-12-19.
