If you want to switch it back to PDF after making your edits, you can simply go back and use the same tool again. To do this, you’d just have to go to our PDF Converter and save the PDF file into one of the three editable formats: Word, PPT or Excel. Smallpdf has Optical Character Recognition (OCR) to extract text from PDF files into editable format again. Either way, the new document will be ‘Read Only’ by the time you save it.
If you are content with the file in JPG format, you can skip the last step and download the file instead of clicking ‘to PDF’. Locking your PDF is beneficial for many reasons, from sharing classified information that you want to be certain can’t be shared with additional people to making sure no one can claim your creative work as their own - such as a photograph of a cool dog in sunglasses. The second step transforms it back to PDF format. To summarize, this process first takes the PDF and renders it into an image file - which prevents not only editing, but also protects the PDF from copying.
