How to · 3 steps

Step by step

  1. 1

    Drop in your clip

    This page opens Lazygif with a square 128 px canvas and Slack’s limits set.

  2. 2

    Keep the best 2–4 seconds

    Trim the clip and crop or Zoom in on the one thing that should read.

  3. 3

    Export and upload

    Lazygif fits it under 128 KB; add it in Slack under Add emoji.

Design for 22 pixels

Emoji show at about 22 px in messages, so detail turns to mush. Pick one subject, crop tight and let it fill the square.

  • One action: a nod, a thumbs-up, a spinning logo.
  • Big shapes and strong contrast.
  • No text, unless it’s one bold word.

Seamless and small

Trim to a moment that ends where it starts. Shorter is the biggest size win; Lazygif lowers the frame rate if the clip is too long for 50 frames.
