How to Add Many Emojis to Slack at Once

First, the Honest Answer

Slack does not have an official bulk upload button. The emoji picker uploads one file at a time. Every method below is a way around that, and each has a tradeoff.

Option 1: The Workspace Emoji Page

Admins and owners can open the emoji admin page at your-workspace.slack.com/emoji. It still uploads one file at a time, but the page is faster for repeat uploads than the picker: name field, file field, save, and the form resets for the next one. With two browser tabs and a folder of files sorted by name, a 50-emoji pack takes about fifteen minutes.

Option 2: A Bulk-Upload Browser Extension

A few browser extensions add multi-file upload to the emoji admin page. They work by automating the same form, so they only do what you could do by hand. Two rules if you use one: pick an extension with a visible source repository and recent updates, and never paste a Slack API token into a tool you have not read. A token with emoji write access can usually do more than add emojis.

Option 3: Split the Work

If your workspace allows any member to add emojis (the default), you do not have to do this alone. Drop the pack in a channel, ask each teammate to upload five, and the pack is in before lunch. Agree on the naming pattern first or you will spend longer fixing names than uploading files.

Before You Bulk Upload

1. Check the files are under 128 KB and roughly square, or Slack will squish them. Details in the size limits guide.
2. Rename files to what people will actually type. The naming guide saves you from a workspace full of final_v2 names.
3. Start with a small batch. Ten emojis your team uses beat three hundred nobody can find.

A Good First Pack

Not sure where to start? The party parrot pack is the classic, blob cats cover most reactions, and the meme pack handles the rest. Every download is already sized for Slack.
