My Outlook PST file size has grown significantly, and it is starting to affect performance. I am looking for the best PST compress tool available in 2025 that can reduce the size of large PST files without causing any data loss or corruption. Preferably, the tool should support batch processing and work smoothly on the latest Windows version.
Can anyone recommend a reliable and secure PST compression software? Also, if possible, please share your experience or step-by-step process using the tool.
If you are a Microsoft Outlook user and have huge PST (Personal Storage Table) files, you must have realized that huge PST files not only slow down Outlook performance but also increase the risk of data corruption. In such a situation, a good PST Compress Tool can help you.
I recently tried DataVare Outlook PST Compact Expert Software and want to share the experience. If your Outlook PST file size has become too big and the performance is slowing down, then this tool has proved to be very helpful:
Advanced Filter: Option to compress only emails from a specified folder or date range.
Backup and Recovery: Keeps your data safe by creating automatic backups.
User-friendly interface: Complete the entire process in a few clicks.
I reduced my 5 GB PST to less than 2 GB, and Outlook is running very fast now. If any mates have used it before or need more suggestions, please let us know in the comments!
I have been using Outlook for some time now, and the size of my PST file has been increasing continuously. This not only slowed down Outlook but also caused it to crash many times. I tried many online solutions – Archiving, Manual Split, but it was either time-consuming or there was a risk of data loss.
Then I came to know about Softaken Compress PST Tool.
What is this tool?
This is a professional software that compresses your huge PST file to a smaller size without any data loss.
Benefits from my experience:
Fast processing – Even files over 4GB were compressed in a few minutes.
Data safety – No emails, attachments or folders were harmed.
There are three options: Save space by deleting attachments, zipping or moving them to a new file.
There was no need to split or archive.
Who is it right for?
If your PST file is getting large and Outlook has become slow, I would personally recommend this tool.
