PDF是文档共享的通用标准。将JPG转换为PDF可以更方便地打印、发送电子邮件和归档照片及扫描文件，同时保留精确的布局。PDF还支持密码保护，非常适合用于存储身份证扫描件、合同和证书等敏感文件。
质量滑块控制图片嵌入PDF时应用的JPEG压缩程度。在90–100%时，输出结果与原图在视觉上完全相同。较低的设置会减小文件大小，但可能会损失细节。对于打算打印的文档扫描和照片，建议使用85%或更高的质量。
JPG和JPEG是同一种格式。JPEG（联合图像专家组）是全称，JPG是旧版Windows系统使用的3字符扩展名。该工具同时接受.jpg和.jpeg文件。
PDF在您自己的设备上、在浏览器中生成。不上传任何图片，不保存任何数据，也没有任何服务器参与——页面加载完成后即使离线也能使用。
