How to Compress a GIF for Email

Email GIFs need to be small — most clients block images over 1 MB, and many mobile users are on slow connections. Here's how to get your GIF email-ready.

Step-by-step guide

  1. 1

    Open GifMash's Email compression page

    Go to gifmash.com/compress-gif-for/email — it's pre-configured with the 1 MB target and 600 px recommended width for email.

  2. 2

    Upload your GIF and check settings

    Upload your GIF. The Target Size tab will be pre-filled with 1024 KB (1 MB). Adjust to 500 KB if you need to be conservative for mobile.

  3. 3

    Compress and embed

    Click Compress to Size. Download the result and embed it in your HTML email. Always set width/height attributes on the img tag.

Tips

  • Outlook 2007–2019 only shows the first frame — design it to be meaningful standalone.
  • Aim for under 500 KB if your audience is mobile-heavy.
  • Use 600 px wide for desktop campaigns; 320 px for mobile-first templates.
  • Keep GIFs under 3–5 seconds in email — attention spans are short.
