Frequently asked questions

How do I resize a GIF without losing the animation?

Upload the GIF, choose a width or a quick size such as 50% or 128 px, and click Resize GIF. Every frame is resized, so the animation and timing stay the same.

How do I make a GIF smaller in file size?

Reducing the width is the most effective way: a GIF at half the width is usually about a quarter of the file size.

What size should a GIF be for Discord or Slack emoji?

Use the 128 px quick size. Both Discord and Slack display custom emoji at small sizes, and 128 px keeps the file light.

Is it free?

Yes. It's free with no sign-up and no watermark.

Is my GIF uploaded anywhere?

No. The GIF is processed entirely in your browser and never sent to Memegician's servers.
