Emoji Explorer

A hand-collected sheet of 351 stickers. Pick the ones you want, then paste a single script into Slack to upload the lot.

Back up your Slack emojis

Save your workspace’s custom emojis, aliases, and metadata in numbered ZIP files, with 200 emojis per file.

  1. Copy the script below.
  2. Open https://YOUR-WORKSPACE.slack.com/customize/emoji while signed in.
  3. Open developer tools → Console, paste the script, and press Enter.
  4. Allow downloads and leave the tab open. Safari starts with a test ZIP; verify it saved, then click “Test saved — start backup”.
Download script

Each ZIP contains image files and a manifest.json with base64, byte sizes, image dimensions, dates, aliases, and metadata returned by Slack. Dimensions describe Slack’s hosted images; the original pre-upload dimensions may be unavailable.

Keep the backup panel open until you have verified every ZIP downloaded. Its links let you retry blocked downloads. Image failures are recorded in the manifest and console report.

To change the batch size, run globalThis.slackEmojiBackupOptions = { batchSize: 200 }; before pasting the script. Values from 1 to 1,000 are supported.

Processing happens in your browser. The script loads fflate from jsDelivr and reads Slack’s emoji API and image URLs. Backups include the workspace metadata Slack exposes, such as uploader IDs and names.
