Programs to open PDFs online

Would you open PDF online, using some Web service useful for the purpose? Before talking to you about this kind of solutions, I always advise you to check their security and privacy conditions; in case of doubts about the treatment of the files uploaded to a service (if it is not clearly stated by what time they are deleted from the servers), it is better to fall back on the programs mentioned in the first part of the article.

Furthermore, I advise you to use online services only if you also need to modify the PDF of your interest: otherwise it would be enough to use any browser capable of opening PDFs (such as the aforementioned Edge).


One of the best solutions for opening and editing PDFs online is PDFescape, thanks to which you can make various changes to your documents directly from the browser. It works for free without installing any plugins, without necessarily having to register (by doing so, however, you have the advantage of being able to save files online) and allows you to upload files with sizes up to 10 MB and a maximum of 100 pages of content.

To use PDFEscape, connect to its main page and load the document to be edited, dragging it into the area Drop PDF Here or, if you prefer, click on the button Choose file, select "manually" the document of your interest and click on the button Upload, to start loading.

Once uploaded, use the PDFescape toolbar on the left to edit the document. You can select one of the three available tabs: Insertion, to use the functions that allow you to insert text, images and other elements in the PDF; Annotate, to add annotations and highlights using the buttons visible on the screen and Page, to take advantage of the functions related to editing the document pages, such as those to rotate them, delete them, and so on.

After reading and (presumably) editing the PDF, click on thegreen icon with arrows, also located on the left, to download the document locally. Simple, right?

  • DocHub - unlike the services mentioned in the previous points, this is not specifically designed to open and edit PDFs but, since it also allows you to act on this type of file, I recommend its use.
