# Difflayer Reviews & Product Details

Difflayer is a browser-based PDF comparison tool for identifying differences in construction plans, site layouts, and CAD outputs with pixel-level precision. Operating entirely within the browser, it processes data locally without external uploads, ensuring GDPR compliance and immediate use without registration. Using pixel-difference methodology, it detects variations between document versions and displays results in seconds. Deviations are marked and numbered for easy navigation. Supporting standard architectural PDF sizes like A0, A1, and A3, it handles files up to 50MB with one-to-one pixel scaling. Users upload an original and revised plan, with discrepancies highlighted via color-coding. Changes such as removed walls, relocated doors, or added windows are clearly visible, aiding revision verification and quality assurance in construction documentation.
