Why formatmath is different
Most online converters upload your files to a server, process them there and send them back. That takes time, limits file size and leaves a copy of your photos and documents on someone else’s computer.
formatmath does the conversion with code that runs in your browser. Your files are read and converted on your own device and are never sent anywhere. It is faster, there is no queue, and it is safe for private things like ID scans, receipts and family photos.
