Can I preview the PEM output before downloading?

Yes. Xonvert shows a preview of your converted file so you can verify the result before saving it to your device.

Can I convert password-protected DER files?

Encrypted or DRM-protected files cannot be converted. You'll need to remove protection first using the original software.

Can I convert multiple DER files at once?

Yes! Drag multiple files into the converter for batch processing. All files convert simultaneously and can be downloaded as a ZIP archive.

What's the maximum number of files I can convert at once?

Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.

Why choose PEM over other formats?

PEM Certificate offers human-readable text format, easy to copy/paste and inspect. It's widely used for SSL/TLS certificates, private keys and certificate chains, making it an excellent choice for most certificate needs.

Will my DER file be deleted after conversion?

No. Your original DER file is never modified or deleted. Xonvert creates a separate PEM copy — your source file remains untouched.

What certificate quality settings should I use?

Default settings are optimized for the best balance of quality and file size. Adjust only if you have specific requirements.
