Shorten GIF online

Free GIF shortener and trimmer: shorten GIF length, cut GIF frames, and remove intros or outros—set start and end frames, preview, download in your.

What is a GIF shortener?

A GIF shortener (GIF trimmer or GIF cutter) removes frames from an animated GIF so the clip plays faster and often weighs less. You choose a start frame and end frame; everything outside that range is cut. This edits the timeline, not the canvas size—use a crop tool for pixel trimming. Upload, set frames, cut, preview, download—all client-side.

Tips for trimming GIFs

Get cleaner cuts when shortening GIFs.
  • 01

    Count from 1

    Start frame 1 is the first frame; end frame includes that frame.

  • 02

    Preview the original first

    Watch the upload to estimate which frame numbers to keep.

  • 03

    Keep at least one frame

    Start must be less than or equal to end.

  • 04

    Speed vs trim

    To play the same frames faster, use GIF Speed Changer instead.

  • 05

    Reverse after trim

    Cut first, then run Reverse GIF if you want the slice backwards.

  • 06

    Large GIFs take longer

    Many frames need more memory—trim on desktop for big files.
