FormatMath is a free file converter that works entirely in your browser. Pick a format, drop your files, done. Nothing gets uploaded to any server.
Why we built it
Most online converters upload your photos, scans and documents to someone else's server. That's not great for ID scans, receipts or family photos. FormatMath does every conversion on your own device, so your files never leave it.
