常见问题
关于图片压缩
图片压缩的作用
图片压缩可以减小文件体积，使图片更容易发送、上传、存储和发布。它适用于网站图片、邮件附件、商品照片、社交帖子、截图和扫描文档。
目标是在保持视觉结果可用的同时让文件更轻。更小的图片通常上传更快、网页加载更快，也占用更少存储空间。
自动压缩与自定义压缩
自动压缩适合快速获得平衡结果。工具会优化图片，不要求手动设置复杂参数。
自定义质量适合需要更多控制的场景。较低质量通常会产生更小文件，较高质量会保留更多视觉细节。
格式与日常流程
JPG 常用于照片，PNG 适合图形和透明背景，WebP 常用于现代网页图片。支持多种格式可以减少来回切换工具。
在上传到网站、通过邮件发送、加入文档或分享到有大小限制的平台前，都可以先压缩图片。
什么时候压缩最有帮助
手机和相机拍摄的大照片通常包含超过日常查看所需的数据。截图、商品图片和导出的图形也可能比需要的更大。
当源图片尺寸较大、分辨率较高或尚未优化时，压缩效果通常最明显。已经压缩过的文件可能缩小较少，这是正常现象。
