How do I shrink an animated GIF to an exact target size (e.g. 5MB for Discord)?

Upload your GIF, enter your target budget in megabytes (e.g., 5.0 MB, 8.0 MB, or 2.0 MB), and the optimizer iteratively scales resolution and color depth to fit under the cap.

How does the target size optimizer work?

The tool calculates file size deltas, tests color quantization thresholds (from 256 down to 64 colors), and applies smart frame skipping to guarantee your output stays below the target limit.

Will the optimized GIF be accepted by Discord and Slack?

Yes. The generated file is guaranteed to be strictly under your specified byte threshold, preventing upload rejection errors.
