About the Slack Emoji Generator
Create custom Slack emoji from text, an image, or an animated GIF. Type a word and add a motion effect — bounce, spin, pulse, shake, rainbow, or blink — to export an animated GIF, or keep it still for a crisp PNG. Upload a picture and apply a filter, or drop in a GIF and keep it moving.
Everything is generated in your browser — text and motion drawn on a canvas, images resized locally, and GIFs decoded and re-encoded frame by frame — so nothing is uploaded and you don’t need an account. Transparent backgrounds are supported for any Slack theme.

- 2Style it. Choose colors, fit, background, and square or circle.
- 3Download & upload. Download the PNG or animated GIF and add it as a custom emoji in Slack.
Frequently asked questions
Can I make an animated text emoji?+
Yes. In “Text emoji”, pick a Motion effect — bounce, spin, pulse, shake, rainbow, or blink — and the tool exports an animated GIF. Leave motion on “None” for a static PNG.
Can I add filters to an image emoji?+
Yes. Upload an image and choose a filter — grayscale, sepia, invert, brightness, contrast, vivid, or blur. Filters apply to still images and to animated GIF frames.
Can I make a Slack emoji from an animated GIF?+
Yes. Upload an animated GIF and each frame is resized to 128×128 and re-encoded as an animated GIF, with the animation preserved.
What size and limit does Slack use?+
Slack recommends 128×128 pixels and a file under 128 KB. Text and static images stay tiny; busy animations can exceed 128 KB — the tool warns you when that happens.
Is anything uploaded?+
No. Your text, images, and GIFs are processed entirely in your browser and never leave your device.
