For M&A advisors and deal teams
Data rooms bill by the page. Make every page smaller.
VDR providers charge for the size of what you upload. PreVDR shrinks scans, images, PDFs and Office files before they reach the room, typically cutting the bill by 30–60%. Everything runs inside your browser.

How it brings the cost down
1. Drop
Drop your deal documents or a whole folder: PDFs, Office files and images, as many as you need.2. Compress
Every file is compressed without losing a single detail and checked against the original. Files that wouldn’t get smaller stay untouched.3. Upload and save
Download one ZIP with every file in its folder, ready to upload. Every file shows what it takes off your provider’s bill.
Maximum compression
Need the smallest possible room?
Maximum mode runs our strongest lossless settings for the smallest files PreVDR can produce. Same pages, same text, same images. Just smaller.
Zero retention, by design
Your files are processed by your own browser, in memory. No upload step, no storage, no logs of file contents. Five independent layers keep it that way, and you can verify each one. Read the security overview.
