怎么把PDF文件旋转90度并保存啊？

1、用WPS打开PDF文档，然后点击进入缩略图页面。

/iknow-pic.cdn.bcebos.com/e850352ac65c1038cbf24038bc119313b17e89b8"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/e850352ac65c1038cbf24038bc119313b17e89b8?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/e850352ac65c1038cbf24038bc119313b17e89b8"/>

2、进入缩略图页面后，按住Shift键全选所有缩略图。

/iknow-pic.cdn.bcebos.com/cc11728b4710b912373a7804cdfdfc0393452255"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/cc11728b4710b912373a7804cdfdfc0393452255?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/cc11728b4710b912373a7804cdfdfc0393452255"/>

3、全选之后，点击工具栏中的顺时针或者逆时针都是旋转90度的。

/iknow-pic.cdn.bcebos.com/8cb1cb1349540923059eed849c58d109b2de4951"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/8cb1cb1349540923059eed849c58d109b2de4951?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/8cb1cb1349540923059eed849c58d109b2de4951"/>

4、旋转好之后，点击PDF文件中的另存为就可以了。
