How to Convert Image File to PDF Format for Free

Sometimes, we run into an awful situation when we have to upload our scanned images on a website; but it only supports the PDF format. If you’re running into such a situation, don’t think that you’re alone. It does happen with a lot of people every day, especially on less-user friendly websites. Read on as we’ll discuss how to convert image file to PDF format.

What is PDF Format? What made it so Popular?

Today, PDF (Portable Document Format) has almost become a global standard for documents. From students to businesses to law authorities, everyone uses PDFs. Can we think of a better example than this?

A PDF document guarantees the integrity of the content. It retains all elements in their original format and looks exactly the same on every device. No matter what kind of device you use, you won’t encounter distortions of any kind.

A PDF can embed interactive contents such as smart forms, audios, videos and images. You can also embed other documents into a PDF.

PDF offers excellent document security with industry-standard encryption. You can password-protect a PDF to restrict who can view or edit it. Not just that, you can change individual permissions for viewing, editing, printing, content copying, commenting, page extracting, form filling, and signing. When you encrypt a PDF, the search engines cannot access the document’s metadata, making your PDF more private than ever.
