Easy to use online PDF editor This is an easy to use app, which allows the editing of PDF files from any source with multiple tools to work on any pdf document of the company, it is a solution for filling out forms, it allows inserting comment or image. I can also combine, divide and reorder, cut, place header and footer, watermark text or image in my documents and has a preview panel. As it is an online editor it does not consume resources on my pc and it is compatible with all browsers You can edit documents from any device but it is mandatory to have an internet connection to use it, so you can not have it as the only editing tool.
