Ever wanted to upload 100 emoji to slack in one fell swoop? Now you can.

1. Install this extension
2. Go to your Slack's /customize/emoji page
3. Drag and drop your emoji image files into the new "Bulk Emoji Uploader". Make sure that the image files are named what you want the emoji name to be ("ditto.gif" will become ":ditto:").
4. You've now got a whole lotta emoji!

Dice Lim 2025-09-02: Awesome
Brian Travis 2024-08-04: great idea, would love it to just automatically replace spaces with dashes and uppercase with lowercase letters in the file names instead of giving me an error. Ended up having to use a shell script to rename all my files
Safeuq Mohamed 2024-07-22: Convenient, simple and straightforward
Brian Richins 2024-07-08: Simple, clean, and minimal permission scope needed. Note that the bulk uploader only appears after your workspace already has at least 1 custom emoji.
Aaron Park (박윤우, Aaron Park) 2024-07-08: The "Bulk Emoji Uploader" shows up when you uploaded at least one custom emoji first.
Raphael Castaneda 2024-07-03: Pretty slick implementation. Love that it supports retrying on rate limit, and reports unsuccessful uploads inline.
Bernard Sanders 2024-05-06: Does not seem to work now, perhaps due to changes Slack made to their emoji uploading page. Can anyone confirm/deny whether it's working for them. I loved this extension while it worked though, and assume it'll be a modest update to get it working again.
Sean Blonien 2024-03-29: Worked without any hiccups 💯
Ahmad Awais 2024-03-28: Perfection! Works like a charm.

P. Zeb Griffin 2022-09-12: Perfect. Exactly as advertised. I used it to uploade 1290 custom emojis to a workspace. No problems.

Anonymous 2022-08-31: still works (shows up as long as you have at least one custom emoji in there) love the error handling, nice touch!

Shia Liu 2022-04-29: This is the first chrome extension I download (lol probably after ad blocker) whenever I get a new laptop. Works like magic!
Platinum X 2022-04-22: Still works! Make sure you have at least one custom emoji added or else the window will not show. Cheers to the creators <3

Shuuji TAKAHASHI (shuuji3) 2022-03-31: Very helpful extension for all who add new emojis frequently or register a lot of emojis at once. I really recommend this extension! 🙂

Lawrence Chan 2021-11-23: Rate limiting workaround: https://developer.chrome.com/docs/devtools/network/#throttle Throttle your connection to a custom rate (I'm using 250/50/300) and it slows the requests down enough to (mostly) avoid the limiting. Much easier to be patient rather than figure out which emojis didn't get uploaded.

David Celis 2021-07-22: Surprisingly still works! Something to note, though, is that Slack rate limits emoji creation… This extension doesn't seem to detect when it's happening. So if you drag and drop too many emoji into the interface, the extension will report them all as having been uploaded, even if many of them were _not_ actually uploaded due to rate limits. I'd recommend dragging and dropping in small batches.

Raynor Kuang 2021-06-02: Good extension, but has trouble with rate limiting from Slack, where it'll silently fail if Slack rate limits you and report "Succesfully uploaded" even if it totally wasn't. A good fix seems to be to detect the upload time -- Slack basically gives an insta-response if it's just silently failing, so an abnormally quick upload for a file is probably a good sign that it didn't actually upload.

Jen McVicker 2021-05-20: If it's not working for you on Chrome, try it on Firefox. The Chrome extension worked for me about a year ago, but when I just installed it on my new mac, it didn't work. Tried it on Firefox and BAM! Bulk uploader is there!

Griffen Fargo 2021-05-06: Careful uploading massive amounts of files via this extension. It seems if you add more than ~25 files at a time the Slack API will start rate limiting the requests causing the rest of the uploads to silently fail despite claiming "upload complete" I have around ~700 custom emojis to add to a new Slack and after dropping all of them into the extension only 125 were successfully uploaded. Go slow and steady to avoid rate limiting.
Felix Mann 2021-04-30: Easy and straight-forward! Does exactly what it says on the tin :D. The best part is: if one of the emoji conflicts, it will still proceed with all the others.
Francesco Visin 2020-10-24: IMPORTANT: You need at least one custom icon installed, for the "bulk emoji uploader" section to appear! It took me ages to figure this out. It should be fixed, or made explicit at least.

Jacob Shavlik 2020-08-31: Works great! Weird bug where the extension doesn't appear in-page unless you have already at least one custom emoji already added.
