What people actually make Reddit emoji for
Reddit emojis are subreddit furniture. They appear in comments and next to flair, and they are one of the ways a subreddit signals its own in-jokes to regulars without spelling them out for visitors.
Added by moderators through the subreddit's own emoji settings, then inserted from the comment composer rather than typed as a code.
Worth knowing before you upload
- Only moderators can add emoji to a subreddit, so this is a mod tool rather than something an individual member can do.
- Emoji render small in comments and beside flair, so detail is wasted and silhouette is everything.
- Reddit's light and dark modes are both heavily used, which makes transparency and a readable outline more important here than on platforms with one theme.

Reddit emoji FAQ
Can I add a custom emoji to Reddit?
If you moderate the subreddit, yes - emoji are managed in the subreddit's settings. Individual users cannot add emoji to a subreddit they do not moderate.
What size should a Reddit emoji be?
A square transparent PNG. Reddit displays emoji small in comments and alongside flair, so a bold simple shape reads where fine detail does not.
Where do subreddit emojis appear?
In comments and next to user flair, which is why they tend to be used for community in-jokes and role signalling rather than general reactions.
