Editing photos is not a problem now, there are so many photo editor options on the Internet. I say this so confidently because I work for an online fashion magazine and can process up to a hundred photos in a day. But my photos are uploaded to the site as a document in PDF format and I, as the author, always sign my works using the online tool https://pdfguru.com/sign-pdf , which is very convenient. This way you can also sign digital documents. It’s amazing how technology has simplified such tasks. I would recommend giving this tool a try, especially if you have a lot of documents that need to be signed online, it has a user-friendly interface and allows you to sign PDFs securely. Try it if you are looking for a reliable solution for working with PDF files!
