Compare PDF

Smart PDF Comparison

• Visual Diff Checking: Instantly spots added, removed, or modified text and images between two PDF versions.
• Auto-Scan Technology: You don't have to check every page manually. Our tool scans the entire document in seconds and flags exactly which pages have changes.
• Smart Overlay: Stacks the two documents on top of each other like a lightbox, making even 1-pixel shifts visible.
• Privacy First: We use advanced browser-based processing. Your sensitive contracts, blueprints, or financial documents are never uploaded to our server.
• Custom Highlighter: Change the difference color (Magenta, Red, Green) to suit your vision preferences.
• 100% Free: No watermarks, no sign-ups, and no file size limits.
