不用花钱!给PDF加水印,一秒钟搞定还免费你是不是也遇到过这种抓狂时刻：下载了一份重要的PDF合同，结果满屏都是别人的广告水印，想自己加个“仅供预览”的声明，却找不到一个不收费的工具？或者网上搜了半天，下载了一堆流氓软件，最后还被勒索收费？别急着花钱买会员。今天直接告诉你一个小程序，手写签字助手，里面有个隐藏的免费功能——PDF加水印，一秒搞定，一分不要。操作有多简单？打开小程序，找到水印功能，上传你的PDF文件。你可以自由调整水印文字（比如“草稿”“仅内部使用”）、颜色、透明度，甚至选择平铺或者单行。整个过程比发条朋友圈还快。不光加水印，它还能顺手帮你把PDF转成Word、图片，甚至直接在上面签字。一个工具干完四五个软件的活。说实话，很多用户之前都是花钱买会员只为了加个水印，知道这个免费功能后都后悔没早点发现。我想问一句： 你手头有没有那种“加了水印才能发出去，但又不想付费”的PDF？评论区说说是哪种文件，我来教你一招更省时的办法。#实用工具 #PDF加水印 #免费办公 #手写签字助手
