Three clear steps

How to compress a GIF

GIF size depends on dimensions, frame count and palette complexity.

  1. 01

    Choose one GIF

    Select an animated GIF up to the stated browser limits.

  2. 02

    Pick a compression level

    Start with Balanced; use Light for detail or Strong when file size matters more.

  3. 03

    Compare and download

    Review the animated result and the measured size reduction before saving it.

Three real levers

How an animated GIF gets smaller

GIF compression is not a single quality number. Tanumi combines palette reduction, dimension scaling and careful frame sampling according to the selected level.

  • Light keeps dimensions and more colors.
  • Balanced reduces palette complexity and dimensions moderately.
  • Strong also samples frames while keeping the total duration.
Choose deliberately

What compression can change

Stronger settings trade more visual detail for a smaller file.

Useful answers

GIF compression questions

Which compression level should I choose?

Balanced is the best starting point. Choose Light when detail matters most, or Strong when you need a much smaller attachment.

Will the GIF still animate?

Yes. The result remains an animated GIF and keeps the total animation duration and loop behavior.

Can compression reduce image quality?

Yes. GIF compression reduces colors and, at stronger levels, dimensions or frames. Always inspect the result before sharing it.

Can Tanumi hit an exact size such as 10 MB?

No. The same settings produce different sizes for different animations. Use Strong or resize/crop the GIF if you still need fewer bytes.

Is the GIF uploaded?

No. The complete compression workflow runs locally in your browser.

Dimensions and empty edges are often the next best size levers.
