批量图片压缩 | 一次压缩多张图片
免费批量图片压缩，提升工作效率
批量压缩时，为所有文件选择一个预设，并始终检查体积最大的输出——单一设置很难适配每张图。若批量混有照片与截图，请按格式拆分：JPEG 处理照片，PNG 处理界面图。

批量压缩技巧
针对使用场景优化
不同场景需要不同的压缩策略。我们的预设专为bulk量身定制。
使用正确的格式
与传统格式相比，WebP 和 AVIF 等现代格式可显著节省文件大小。
批量处理相似图片
使用我们的批量压缩功能，用相同设置处理多张图片，节省时间。
保存前预览
下载前务必检查压缩结果，确保符合您的质量标准。
Best format for this task
Why JPEG works well
- • photographs
- • gradients
- • complex real-world scenes
Alternatives to consider
- • WEBP: transparency support and better compression at similar quality
- • PNG: lossless output when alpha or text edges must stay crisp

Encoded with the codecs this tool ships, on a synthetic set covering screenshots, photos and logos. Sizes are actual output bytes, not estimates.
