Frequently Asked Questions

Common questions about DWG to PDF conversion

How does in-browser DWG to PDF conversion protect my privacy?

Unlike legacy file converters that upload your confidential files to cloud servers, OpenFileConverter runs 100% locally on your computer or phone using Rust WebAssembly. Your original DWG files never leave your device memory, guaranteeing zero retention.

What is the main difference between DWG and PDF?

DWG (Autodesk AutoCAD Drawing Database) provides architectural blueprints, civil engineering plans, and autocad production drawings, while PDF (Portable Document Format) is optimized for multi-page documents, contracts, archivals, and print-ready proofs. Converting allows you to balance file size, compression fidelity, and platform compatibility.

Does converting DWG to PDF degrade visual quality?

No. OpenFileConverter uses high-fidelity chroma subsampling with configurable quality levels (default 92%), ensuring virtually indistinguishable image fidelity with sharp edges and rich colors.

Can I convert multiple files in batch?

Yes. You can drag and drop up to 100 files simultaneously. Because processing executes in parallel on your local CPU threads, batch jobs finish in seconds without queue wait times.
