DraftPlanar - PDF Plan Viewer

Fast, offline PDF viewer for iPad, iPhone, and Mac. View large blueprints and floor plans side by side on an infinite canvas with 60 FPS performance.

DraftPlanar is a fast, offline PDF viewer and annotation tool for iPad, iPhone, and Mac. Open large documents — blueprints, floor plans, technical drawings, or any PDF — and view them side by side on an infinite canvas with 60 FPS performance.

Unlike single-page PDF readers, DraftPlanar lets you lay out multiple documents at once. Place a floor plan next to a section detail. Compare two versions of a drawing. Pin reference images alongside your specs. Work the way professionals do — with everything visible, not buried in tabs.

WHAT YOU CAN DO

• View & Navigate Large PDFs Open 500+ page documents and zoom in at 60 FPS. Our Metal-native rendering pipeline keeps massive PDFs razor-sharp at any scale. Smooth panning and pinch-to-zoom, optimized for Apple Pencil and trackpad.

• Measure & Dimension Calibrate your drawings to real-world scale. The Precision Measure tool snaps to path vertices, midpoints, and edges in the PDF's vector geometry — accurate to the line.

• Annotate with Apple Pencil Draw, sketch, and redline with a GPU-accelerated pen tool that produces smooth, variable-width strokes. Non-destructive layers keep your annotations separate from the original document. Includes a precision eraser.

• Search & Select Text Find details instantly in large specification books. Keyword search with color-coded highlights. Select text via the built-in OCR engine and highlight key sections with the Marker tool.

• Compare Document Versions Place two revisions side by side and spot differences. Perfect for reviewing plan updates, spec changes, or contractor submissions.

• Control PDF Layers Toggle individual layers in complex PDFs. Filter and search layer names (supports regex) to isolate exactly what you need.

• Paste Any Reference Drop images, SVGs, Markdown notes, or HTML onto your canvas. Everything converts to crisp vector objects automatically.
