What's the difference between CER and CRT?

CER Certificate is certificate file — common alternative extension to crt. Certificate File is common certificate file that can be in pem or der encoding. Key difference: CER Certificate excels at identical use to CRT — just an alternative extension name, while Certificate File offers widely recognized extension for SSL/TLS certificates.

What happens to my files after conversion?

Nothing — your files exist only in your browser's memory during conversion. Once you close the page, all data is cleared. No files are stored anywhere.

Will the conversion strip my EXIF or metadata?

Does the conversion preserve metadata?

Xonvert preserves compatible metadata fields when converting between formats. Some format-specific metadata may not carry over if the target format doesn't support it.
