Can I convert multiple CER 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 P7B over other formats?

P7B Certificate Chain offers contains complete certificate chain without private keys. It's widely used for distributing CA certificate chains and intermediate certificates, making it an excellent choice for most certificate needs.

Will my CER file be deleted after conversion?

No. Your original CER file is never modified or deleted. Xonvert creates a separate P7B 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.

Does this work on my phone or tablet?

Yes. Xonvert works on any device with a modern browser — iPhone, iPad, Android phones and tablets all supported.

Can I undo a conversion?

Since your original CER file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new P7B copy is created.
