Can I convert PEM to CRT in bulk for free?

Yes. Free users can batch-convert multiple files. Simply drag all your PEM files into the converter at once. PRO users get higher batch limits and priority processing.

What's the difference between PEM and CRT?

PEM Certificate is base64-encoded x.509 certificate or private key in ascii format. Certificate File is common certificate file that can be in pem or der encoding. Key difference: PEM Certificate excels at human-readable text format, easy to copy/paste and inspect, while Certificate File offers widely recognized extension for SSL/TLS certificates.

How does the PEM to CRT conversion work technically?

Xonvert uses WebAssembly-compiled libraries to decode your PEM file in-browser, process the certificate data, and re-encode it as CRT. All processing happens on your device's CPU.

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.

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.
