PDF tools for architects and engineers

Compress and combine large drawing sets — without the upload wait.

Plan sets and drawings are large and often confidential. RobinPDF handles them in your browser, so there's no slow upload, no file-size cap from a server, and nothing leaves your device.

Tools

No upload wait on big files

Heavy drawings are processed locally, so you skip the upload-and-download round-trip entirely.

No server size limits

The only limit is your computer's memory — handy for large, multi-page plan sets.

Tender & client privacy

Confidential drawings and tender documents never reach a third-party server.

Handy for drawings & plans

Built for large, private files

Uploading a 200 MB drawing set to a cloud tool is slow and exposes it to a third party. RobinPDF processes it in your browser, so it stays on your machine and there's nothing to wait for.
