The tutorial shows the automatic way to shrink PST file size without data loss.<\/p>\n<p><a href=\"https:\/\/www.adviksoft.com\/pst\/\">PST is a file format<\/a> which is an Outlook data file to store and organize Outlook emails. However, these PST files can grow in size and take up valuable storage space on your system. That&#8217;s why, many users want to compress the PST file size to get a reduced PST file size that can be used effectively and efficiently. Although compressing the PST file will reduce the quality of data embedded in it but it will also decrease the size of PST file making it much easier to send multiple PST files altogether.<\/p>\n<div class=\"blue-border\">\n<h2>Why Need to Compress PST File Size?<\/h2>\n<p>In PST files, all the email content and related information are saved in a single file format. All the emails and messages are saved in this single file. Hence, the size of the PST mailbox file is also getting increased. Hence, users find it difficult to store and access. Also, it causes various issues in working with this large-size PST file such as errors in opening PST file, incompatibility with Outlook as <a href=\"https:\/\/www.adviksoft.com\/blog\/how-to-fix-large-pst-file-crashes-outlook-while-opening-issue\/\">large PST File crashes Outlook<\/a> while opening or corruption or damage issues, etc.<\/p>\n<p>So, in this section we will discuss some basic needs and requirements of the users to reduce PST file size;<\/p>\n<ul>\n<li>Large PST file sizes can easily impact the performance of Outlook which leads to slower response due to which you <a href=\"https:\/\/www.adviksoft.com\/blog\/solve-cannot-export-outlook-pst-file-error\/\">cannot export Outlook PST file<\/a> and also delays in searching and accessing its emails.<\/li>\n<li>Reducing PST file size allows for better storage management as smaller files are easier to backup, transfer, and store.<\/li>\n<li>When PST files exceed their size limit, they become more prone to corruption, which can result in data loss or the inability to access important emails and attachments.<\/li>\n<li>By reducing PST file size, you minimize the risk of data loss. If a large PST file gets corrupted, you may lose a large number of crucial emails, contacts, or attachments.<\/li>\n<li>Smaller PST files are more portable and can be easily transferred which ensures seamless access to your emails wherever you need them.<\/li>\n<\/ul>\n<\/div>\n<p>In short, compressing PST files is important as it saves storage space and improves the performance of Outlook email client. So, if you haven&#8217;t already, consider reducing PST files now to get these benefits of using the solution explained in the below section.<\/p>\n<h2>How to Reduce PST File Size Without Outlook?<\/h2>\n<p><a href=\"https:\/\/www.adviksoft.com\/pst\/splitter.html\"><strong>Advik PST Splitter Tool<\/strong><\/a> is the best software to reduce PST file size safely.
