ComparePDF is a free, private PDF comparison tool that lets you analyze text and visual changes between two documents entirely in your browser. Your files never leave the tab, ensuring sensitive data stays secure and private.
Key benefits include:
- Private by Design: Documents are processed locally in your browser tab—no cloud uploads, history, or sharing links.
- Dual Comparison Modes: Visual comparison for layout changes and selectable text/OCR for content changes (supports English scans for first 20 pages).
- Flexible Views: Side-by-side, overlay, slider, or difference-map views to review changes at your preferred angle.
- No File Limits (Up to 25 MB): Each PDF can be up to 25 MB, with a simple 3-step workflow: drop PDFs, review pages, confirm text.
Perfect for professionals reviewing contracts, reports, or scanned archives who need to verify changes without compromising privacy or sending documents to external servers.
