How to Resize PDF Online to Reduce File Size

PDF files are ubiquitous in today's world of business. They are now the preferred way to share information on the web, via email, and even on social messaging and social media platforms.

However, their popularity as a consistent and platform-agnostic content format means that large portions of information are often stored as PDFs - the problem comes when sharing them since most sharing channels have specific file size limits.

To counter this issue, you can resize PDF online to reduce their file size. The process is complicated and has several moving parts, but you can make it easy by using an online PDF file resize service. This article showcases three popular PDF resize converter websites that offer excellent compression quality at various price points.

Part 1: FAQs about Resizing PDF Online

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?

Some 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.

Part 2: How to Resize PDF Online for Free
