图片过大常拖慢网站加载、挤占存储空间，并影响搜索引擎抓取效率。**[图片压缩](https://imagecompressor.com/zh/)** 是 imagecompressor.com 推出的在线工具，专注优化 JPEG、PNG、WebP、GIF、SVG 五种主流格式，所有处理在浏览器本地完成，文件不会上传到任何服务器。

## 图片压缩 解决什么问题以及适合谁用

该工具的核心场景是把过大的图片文件压到合理体积，从而缓解网页加载变慢、邮件附件超限、手机相册占空间等具体问题。目标用户覆盖较广：

-   网站站长和博主优化首图以提升页面加载速度
-   社交媒体运营把图片压到各平台上传上限以内
-   摄影师导出网络版本作品
-   电商运营批量压缩商品图

由于处理全程在客户端完成，对隐私敏感的医美、金融、政务类用户也能放心使用，无需担心素材外泄。

## 从上传到下载的功能全链路

格式覆盖以 JPEG、PNG、WebP、GIF、SVG 五种主流格式为核心。底层基于 WebAssembly 技术，在浏览器内完成原本需要本地软件的解码和编码工作。官网对每种格式给出明确策略：

| 格式  | 压缩策略 |
| --- | --- |
| JPEG | 默认目标质量为 80，工具会从量化表反推原始质量避免重复压缩 |
| PNG | 转换为最多 256 色的 PNG8 以保留透明度 |
| WebP | 在同等视觉质量下比 JPEG 小 25%-35% |

批量处理不设张数上限。用户拖入图片后，工具按每张图特性自动选择压缩策略，也可手动微调质量滑块。压缩完成后可通过对比视图滑块调整后再决定下载。对于一次性需要处理几十张甚至上百张图片的电商场景，比传统桌面软件更省去安装和授权步骤。

## 上手只需四步

访问 imagecompressor.com，把图片拖入指定区域；等待浏览器本地处理完成；预览压缩前后对比；点击下载。整个流程无需注册，不限每日使用次数，输出图片不添加水印。

## 隐私保护与边界条件

该平台核心卖点同时也是主要限制：所有处理在客户端完成，意味着工具不会主动备份用户文件，关闭页面后图片即刻消失，重启浏览器无法找回。压缩过程会自动清除 EXIF、GPS、相机参数等元数据，需要保留拍摄信息的摄影师要提前备份原始文件。

批量处理包含中文路径或超大文件夹时，浏览器内存占用会明显上升，建议分批处理，单次控制在 100 张以内更稳定。官网未提供独立 API，开发者想接入自动化流程需要绕道其他方案。
