所有处理都在浏览器本地完成，无需上传文件。
Is this preset reasonable for Instagram?

Can I compress PNG 压缩到 200KB 以下?
Yes. Start with this preset, then adjust quality or width if your exact file-size target needs more tuning.
Which output format does this preset use?
This preset exports as PNG. You can still change the format before downloading.
