GIF Cutter

Trim animated GIFs by selecting start and end frames directly in your browser. Cut unwanted sections, reduce file size instantly, and keep your files private.

GIF, APNG, WebP, AVIF · static images are accepted too

Tips

  • Drag the start and end handles on the frame timeline to select the exact section you want to keep.
  • Frames outside your selected range are removed entirely, reducing the final file size proportionally.
  • To split an animation into multiple distinct segments, run the tool once for each required range.

How to use it

  1. 1 Select or drag your animated GIF file into the trimmer.
  2. 2 Adjust the start and end markers on the frame timeline to isolate your target segment.
  3. 3 Preview the trimmed playback duration and download your exported GIF.

What you should know

GIF file format stores uncompressed or LZW-compressed raster frames, causing file sizes to scale linearly with frame count and duration. Unlike modern video formats with delta encoding, animated GIFs carry up to 256 indexed colours per frame, making lengthy animations excessively heavy for web embeds, messaging apps, and email newsletters. Trimming superfluous lead-in seconds or dead loops directly eliminates redundant frames, dramatically cutting payload without sacrificing visual quality. Because frame rates remain intact, you retain original playback speed while meeting strict asset size restrictions.

This tool decodes your GIF into individual canvas frames and extracts your chosen range entirely inside your browser. When you isolate a segment, the built-in encoder recalculates the palette for the remaining frames and rebuilds the graphic control extensions that govern timing. Discarded frames, non-standard embedded metadata, and unselected frame disposal methods are stripped out during export. Single-color index transparency is preserved across kept frames, but no audio tracks are produced since the standard GIF specification does not support sound.

Frequently asked questions

Does cutting a GIF reduce its overall file size?

Yes, removing unwanted frames directly eliminates raw image data and timing metadata, lowering the final byte count proportionally to the number of frames discarded.

Will the image resolution or frame rate change when trimmed?

No, the output keeps the exact pixel dimensions and frame delay intervals of the original animation unless you modify those parameters separately.

Are my uploaded GIF files saved on any external servers?

No, all frame decoding, cutting, and re-encoding occur locally in your web browser memory, ensuring your media never leaves your device.
