Frequently asked questions

Is my data sent to a server when I convert it?
No. These tools parse and convert data in your browser, so sensitive data never leaves your device.
Can these tools handle large files?
Yes, within the limits of your device's memory. Multi-megabyte files generally work fine on a modern machine.
