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.
ToolsNo 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.
