Frequently Asked Questions

Common questions about WOFF to WOFF2 conversion

How does in-browser WOFF to WOFF2 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 WOFF files never leave your device memory, guaranteeing zero retention.

What is the main difference between WOFF and WOFF2?

WOFF (Web Open Font Format 1.0) provides legacy web font serving and cross-browser desktop typography, while WOFF2 (Web Open Font Format 2.0) is optimized for core web vitals performance, modern responsive web typography, and low cdn bandwidth. Converting allows you to balance file size, compression fidelity, and platform compatibility.

Does converting WOFF to WOFF2 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.
