Custom Emoji Libraries Compared: Which One Fits Your Workflow?

The Short Answer

• Teamsmoji: best fit here for workplace discovery across Microsoft Teams, Slack, and Discord, especially if you want chat-size previews and a local maker in the same flow.
• Slackmojis: fastest familiar browse for Slack users who already think in shortcodes and want a simple popular feed.
• emoji.gg: strongest of these four for Discord-led community browsing, themed packs, and user-curated server culture.
• MakeEmoji: strongest maker-first choice when you already have a photo, logo, or idea and want effects and platform exports.

How We Compared Them

We checked six things: relevance to workplace reactions, usable catalog depth, platform-specific checks, built-in editing, download friction, and visible cost. Catalog size alone did not win the comparison. A library is useful only if someone can find a readable reaction, understand where it works, and get it into chat without unnecessary steps.

Teamsmoji: Best Workplace Workflow in This Rubric

Teamsmoji combines a 100,000-plus searchable library, curated packs, individual detail pages, Teams/Slack/Discord chat-size previews, one-click downloads, and an in-browser maker. It is Teams-first but not Teams-only. That makes it the best fit in this rubric when the job starts with “find a useful work reaction” and may end with resizing or customizing it.

The tradeoff is breadth: a huge inherited catalog contains plenty of novelty and fan-made material alongside workplace reactions. Start with Reactions, curated packs, or the small reaction set guide instead of treating the full library as a shopping list.

Slackmojis: Best for Familiar Slack Shortcodes

Slackmojis opens on a popular feed and familiar sets such as Hangouts Blob, memes, Blob Cats, and Party Parrot. It is fast when you already know the Slack-style name or visual family you want. Downloads are direct and the site has a simple image maker.

Its public maker currently says it accepts PNG, JPG, and WebP while animated GIF support is coming soon. The site is Slack-centered, so people planning a Teams rollout get less platform-specific guidance than they do on Teamsmoji.

Emoji.gg: Best for Discord-Led Community Browsing

emoji.gg presents thousands of community emojis for Discord, Slack, and other chat products. It has categories, user-curated packs, ZIP downloads, and a maker assembled from Twemoji-based and custom parts. If your culture starts in Discord and you want themed community art, that is the clearest fit.

Community variety also means the workplace signal is weaker. Check readability and rights for the exact asset you choose rather than assuming every popular upload belongs in a company workspace.

MakeEmoji: Best When You Need to Make, Not Browse

MakeEmoji leads with creation: upload an image, adjust background, animation, size, or format, and export for a platform. Its public pages include dedicated Slack and Discord workflows plus collections for people who want a starting template.

Choose it when your source is already known, such as a coworker photo, mascot, logo, or inside joke. Choose a discovery-first library when you need ideas or a reusable reaction vocabulary before you need editing controls.

Cost and Friction

Browsing and ordinary downloads were publicly accessible on all four sites during this check. Teamsmoji did not require an account for library downloads or its local maker. Slackmojis exposed direct downloads. Emoji.gg exposed individual downloads and packs. MakeEmoji exposed a free maker flow and also promoted broader services. Pricing, account gates, and limits can change, so recheck before a large team rollout.

The final upload still happens in your chat product. For Slack, the official custom emoji guide notes that owners can restrict who adds emoji and that aliases can make existing emoji easier to find.

Pick the Workflow, Then Test One File

Do not migrate a giant pack because a homepage looks impressive. Find one reaction, preview it at chat size, download it, upload it to the actual workspace, and see whether coworkers can find and understand it. If that loop is clean, repeat it for a small set. If it is not, switch tools before you create a cleanup project.
