One of the important features of PDF files is that it is not easy to edit the PDF files, in fact it is mostly used because of this feature only which serves as its advantage. But there are occasions when we need to watermark the PDF file, convert to some other format or split and join into smaller parts.
With the help of an online utility called PDFaid we can perform many things on our files like we can split a PDF file into many files, join the PDF files in one, watermark our PDF files with some text of our choice or convert a doc into the PDF format. In short, it is a simple and single tool for most of your PDF requirements.
What you all need is just open the below mentioned website, select your operation to be performed, browse for your PDF file and perform the remaining actions. Like to watermark your file, browse your file, select the text and color options and click the Watermark PDF button. You can then download the converted/operated file from the link afterwards.
Although the tool is not completely free but you can use the utility with some size restrictions on the site.
