Frequently Asked Questions
What size should a GIF be for Slack custom emojis?›
Slack requires custom emoji to be under 128 KB and recommends 128×128 pixels. After generating your GIF, you can use the GIF Compressor tool to reduce file size if needed before uploading to Slack.
How do I add a custom animated GIF emoji to Slack?›
In Slack, go to Settings → Customize → Emoji → Add Custom Emoji. Upload your GIF file, give it a name (e.g., :celebration:), and it will appear in your workspace emoji picker for everyone to use.
Can I make a GIF of a coworker or team photo for Slack?›
Yes. Upload any portrait or team photo using the Image-to-GIF tool, select the Portrait animation style, and download the GIF. It works perfectly as a custom Slack emoji or reaction.
What animation styles work best for Slack emojis?›
Subtle animations work best in small emoji sizes — Portrait (gentle expression), Logo (soft pulse or glow), and Reaction styles all look great at 128×128. Avoid overly complex animations that lose detail when scaled down.
Is it free to make GIFs for Slack?›
Yes. The free tier gives you 1 animated GIF per day. Sign up free for 150 bonus credits plus 3 extra free generations to start. For unlimited generations and higher resolution, use Standard or Pro credits.
Can I use a text prompt instead of uploading an image?›
Yes. Switch to the Text-to-GIF tab and describe what you want — "celebration confetti explosion", "thumbs up with sparkles", "rocket launching upward". The AI generates a looping GIF from your description.
