- The file size that can be processed depends on your device. The limit for your device is shown in the drop area, and files above it are refused with a message.
FAQ
Is my file uploaded to a server?
No. Conversion happens only inside this browser, and file names, contents and results are not sent to our servers. Some converters download their conversion program (code) the first time you use them; your files are not sent then either. See the privacy page for details.
