Frequently asked questions
Will images look okay?
Yes - the conversion maps colours to appropriate grey tones so images remain clear and readable.
Is it private?
Everything runs locally in your browser using WebAssembly. Because no data is uploaded to a cloud server, your files remain strictly private, and the entire process generates zero server carbon emissions, making it highly eco-friendly.
