How to Convert PDFs on iPhone or iPad

Do you know what PDF is and why it is so popular when businesses exchange documents?

PDF, representing Portable Document Format, is a widely exchanged online file type for multiple purposes, such as education, job application, business corporations, etc. Although PDF tools have improved a lot, allowing users to directly highlight, edit or copy words on PDF files, applying modifications or large-scale adjustments is still hard to achieve. In this case, converting PDF’s format to Word, Excel, PPT, etc., is needed. Then how could we achieve the conversion? A PDF converter could help. There’re numerous options in the market and hence, choosing the right one is not easy. In this post, we are going to share with you some easy and handy solutions of PDF conversion.

Why Convert to PDF File

Before we move on to introduce how to convert PDFs, let’s have a brief review of why PDF is so frequently used.

  • Universal Compatibility

PDF files could be recognized by any operating system. That is to say, you can feel free to open the file whether using Windows, Linux or whatever else.

Although PDF is supported by Adobe Acrobat, it doesn’t require users to install Adobe Acrobat Reader to view, print out or forward it.

As PDF is featured with universal compatibility, it is accessible to a wide range of audiences, covering those who are using smartphones, tablets, computers, Kindle or other screen reading tools. PDF makes document sharing more convenient.

  • Data Security

PDF files allow encryption. You can set passwords or electronic signatures to secure your personal or confidential information before sending out the files. Only those who are authorized can access the file, adding extra security to the content. More importantly, PDF can’t be edited as easily as Word files. Data tampering is hence effectively prevented.

Additionally, sometimes the layout of the document might be changed when it is sent out and opened on another device. Page layouts like margins, orientation or font size are fixed in PDF, providing a comfortable reading experience and making your files look more professional.

  • Space-friendly

We might be annoyed with bursting disk space with mountainous files. Instead, by turning into a PDF file, even high-quality files are compressed into smaller file size. Compared with other document types with the same content, PDF takes up less space on your devices. With smaller file size, it takes less time to open, forward through emails or upload to the Cloud.

How to Convert PDFs

PDF files are easy to mark or annotate. However, editing data or formulas, CAD sheets or pictures inserted on PDFs is barely possible. The only way to make this come true is transforming PDFs to other file formats first, including Excel, DWG, Word, etc. The transforming process is various and some methods are easy. For example, desktop software, apps, as well as web-based platforms are all listed in the following post. All you need to do is pick the right one.

The “Save-as” Feature

Microsoft Office documents could be saved as PDFs directly. Click “Save as” and then choose “PDF” in the drop-down list of the text type. As a built-in feature of Microsoft Office, only Word, Excel, and Powerpoint to PDF conversion could be realized.

If you want to change PDF to Word, you can right-click the file and choose “Open with” option. Select “Word” or “Microsoft Word” and the file would be shifted into editable Word file, but the results of transformation might look different from the original PDF, especially when there are a large number of images or sheets included. Layout problems or messy codes after converting would add difficulty to understand what the file is about.

Use Apps to Convert PDFs

In order to preserve the original form of the file, a PDF converter is more favorable. By downloading a converting app on your cellphone, you can handle batches of format transformation tasks with one tool. For example, UPDF is one of the most popular apps. It supports both Android and IOS systems. Users can not only convert PDFs but also view, edit and annotate them. This app allows you to convert PDF to popular Office files (eg. Word, Excel, PPT, CSV), to image files (eg. png, jpeg, git, tiff), to text or Plain Text and Rich Text Format (RTF), to HTML/XML and to PDF/A. Another specialized feature to convert PDF into editable format is the built-in OCR technology which scans the PDF files and turns it into editable text. This app charges monthly fees ranging from $29.99 to $49.99. Annual or perpetual plan are available.
