SharePad
Browser-based PDF workbench for architecture, engineering, and construction teams. Upload any drawing size, mark it up, combine sheets into a master workbench, and share the whole thing with a single link — no install, no account required to view.
What it does
Upload & View Large PDFs
Upload drawings of any file size and view them instantly in the browser — no waiting, no converting. Engineered for large engineering and architectural documents that crash ordinary viewers.
Workbench
Combine multiple drawings and PDF sheets into a single master workbench. Navigate across all drawings from one view — no switching between files or losing context mid-review.
Markup & Collaboration
Annotate drawings directly in the browser. Add comments, highlight areas, and mark up sheets — all without downloading anything. Share markups with the team via the same link.
Cloud Storage
All drawings and workbenches are stored securely in the cloud. Access your projects from any device, any browser — your drawings are always where you left them.
Single-Link Sharing
Share an entire project — all drawings, all markups — with one link. Recipients can view and navigate without signing up or installing anything. Perfect for client reviews and contractor handoffs.
Teams / WhatsApp / Email Integration
Share projects directly to Microsoft Teams channels, WhatsApp groups, or via email. The link opens in any browser — no app download required for recipients.
Who it's for
Architects
Share full drawing sets with clients and review teams without email attachments or file size limits.
Engineers
View and mark up large structural, MEP, and civil drawings directly in the browser during site reviews.
Building Managers
Keep as-built drawings accessible to facilities staff and contractors without managing file versions.

Access the latest drawing revisions from the workbench link on-site — on any device, no install needed.
