How to · 3 steps

Step by step

  1. 1

    Record or drop in a clip

    Trim to the bit worth sharing and caption it if needed.

  2. 2

    Pick the destination

    Choose Discord, Slack, Slack emoji or Discord emoji; Lazygif sets the size.

  3. 3

    Export and paste

    Drag it into the message box, or upload it as an emoji.

The limits that matter

Slack takes files up to 1 GB, but big GIFs stall busy channels.

  • Discord message: 20 MB on a free account.
  • Slack message: aim under 10 MB.
  • Slack emoji: 128 KB, square, up to 50 frames.
  • Discord emoji: 256 KB, 128×128; animated emoji need Nitro.

Emoji that read at tiny sizes

Emoji show far smaller than 128 px. Crop tight on one subject, use bold motion and keep the loop short. The Slack emoji GIF page opens Lazygif with this set up.
