Large dimensions, photographic noise, alpha, many animation frames, and a mismatched codec can resist ordinary quality changes. Identify the cause before compressing harder.

Count pixels and frames first
Width multiplied by height gives the pixels in one frame. Animation multiplies that workload across frames. A modest-looking file can still contain a very large decoded image that needs careful resizing.
Match content to a codec
Detailed photos usually fit JPEG, WebP, or AVIF. Sharp text and flat graphics often suit PNG or lossless WebP. Saving a camera photo as PNG can turn a reasonable JPEG into a much larger file.
Know when the target is unrealistic
A detailed transparent image cannot always reach a tiny KB cap at useful dimensions. Try a modern alpha-capable format, crop unused space, or relax the target rather than accepting a visibly broken result.
