Resize PDF Online - FAQs

Q1: When should I resize a PDF file?

If you need to send a file quickly via email or chat, you may need to reduce the file size beforehand. In some cases, a large number of files is stored on a memory device, and optimizing their sizes allows you to save more files on the device. PDF resizing is also useful when you want to display the information on the web because large files tend to be slower to render on a browser such as Chrome or Edge.

Q2: What are the three ways to resize PDF online?

Whether online or offline, resizing PDFs involves either optimizing the file as a whole, reducing the size of each page, or reducing image size. All of these have the effect of making the file smaller and are suited to different purposes. The choice will depend on the type of content and the specific file that you need to optimize.

Q3: Is online or offline PDF resizing better?

ome users prefer using an online service since it's convenient and you can basically access it from anywhere without having to download or install anything. However, there may be some security risks when dealing with sensitive PDF content, especially if you're using a public Wi-Fi network or one that is not fully secure. Desktop solutions are ideal for this, but you may need a high-end computer or device to optimize very large PDF files. Weighing these pros and cons will help you make the right choice.
