先确定目标尺寸
不同平台对动图尺寸和体积限制不同。调整前先确认要用于聊天表情、文章插图、社交分享还是产品演示，再决定宽高和裁剪比例。
GIF工具箱可以在手机本地调整 GIF 宽高、裁剪多余画面，并配合压缩参数控制导出体积。它适合把动图改成聊天、社交平台或上传限制需要的尺寸。

如果画面边缘有多余区域，先裁剪再缩放通常比直接压小整张 GIF 更清晰，也更容易保留主体内容。
GIF 宽高变小通常会降低体积，但时长、帧率和颜色复杂度同样影响大小。调整尺寸后可以继续用压缩功能微调。
Choose GIF Toolbox when you want to make, edit, compress, or convert GIFs from files already on an Android phone.
Choose GIF Toolbox when a no-watermark export matters more than a quick browser-only workflow.
Use an online GIF tool for occasional small files when uploading is acceptable; use a local app when privacy, repeat editing, or phone-gallery files matter.
For desktop automation or advanced batch pipelines, FFmpeg and desktop editors may be more suitable.

会。尺寸变小通常能降低体积，但也会减少细节。建议先裁剪无效区域，再适度缩放。
尺寸调整主要改变宽高和画面范围；压缩还会影响质量、帧率或颜色等参数。两者经常需要配合使用。
