任何图像编辑程序都可以减少

JPG。我们向你展示如何快速和容易地做到这一点。你不需要很多以前的知识来做这个。

用油漆还原JPG图像

  • 打开油漆。
  • 点击左上方的 “文件”-“打开”,选择适当的文件。
  • 点击菜单栏中 “图像 “标签中的 “调整大小”。
  • 请确保激活 “保持长宽比 “选项。现在,要么改变像素数,要么按百分比调整图像大小。
    • 保存更改,并将文件放在你选择的位置上。

    用Irfanview减少JPG

    使用Irfanview,你可以轻松地一次调整许多图片的大小

    • 启动Irfanview并选择 “文件”☻”批次(批量)转换/重命名… “
    • 现在,批量转换窗口打开。在此选择 “选项”。
    • 另一个小窗口打开,你可以用滑块设置图像的质量。用 “OK “确认这一设置。
    • 选择所需的图片,用 “添加 “按钮将其添加到列表中。
    • 选择一个所需的目标目录,用 “开始 “按钮开始进程。
      • 因此,所有添加的图像将被调整大小,并在几秒钟内导出到选定的文件夹。

      • 在批量转换中,点击目标格式左边的 “选项 “按钮。
      • 在这里,你可以用不同的方式改变文件大小。勾选 “设置文件大小 “并选择所需的文件大小。图像被压缩,使文件大小保持在选定的尺寸内。用 “OK “确认。
