How to Use GIF Optimizer

  1. 1

    Upload Animated GIF

    Select an animated GIF to analyze. The tool parses frames locally for complete privacyā€”no uploads.

    Tip:Higherā€‘resolution GIFs benefit more from resizing.
  2. 2

    Adjust Resize & Quality

    Set a resize percentage and encoding quality to reduce dimensions and file size while preserving motion.

    Tip:Try 50ā€“75% scale and quality 10ā€“15 for balanced results.
  3. 3

    Optimize or Extract

    Click Optimize GIF to rebuild a smaller animation, or Extract Frames to download each frame as PNG in a ZIP.

    Tip:Use frames for advanced edits in external editors if needed.
  4. 4

    Download Output

    Save the optimized GIF or frame archive for use in docs, issues, or web pages.

    Tip:Keep both versions: animated for sharing, frames for archiving.

Security & Privacy

  • GIF optimization and splitting runs in your browser.
  • No files are uploaded, logged, or stored.
  • Very large GIFs can exhaust memory ā€” split or downsize first.

Performance Tips

  • Reduce frame count or dimensions to lower memory usage.
  • Prefer WebP for animations when possible for smaller sizes.
  • Use frame extraction for precise edits and recomposition.

Frequently Asked Questions

Is my GIF uploaded anywhere?

No. Optimization and splitting run entirely in your browser. Files never leave your device.

What controls affect size most?

Downscaling dimensions (Resize %) usually yields the biggest savings; encoding quality also helps reduce bytes.

Can I edit frames after extraction?

Yes. Download PNG frames (zipped) and edit them with any image editor, then reā€‘assemble if desired.

Does it support very large GIFs?

Large files may be memoryā€‘intensive in the browser. Try stepā€‘wise downscaling or shorter clips for best results.

Are transparency and delays preserved?

Frame delays are applied on reā€‘encode. Transparency support depends on the source and encoder settings.

Why is quality lower better?

gif.js uses a quality parameter where lower values typically produce better compression.
