Convert PEM to P7B
Fast, free, and secure PEM to P7B conversion. No registration required.
No app to install, no account to create — just open this page, drop your pem file, and get p7b output in seconds. What makes this conversion useful: PEM Certificate gives you human-readable text format, easy to copy/paste and inspect, but P7B Certificate Chain unlocks distributing CA certificate chains and intermediate certificates — something PEM Certificate struggles with (not binary-efficient, larger than DER encoding). This is one of the most frequently used conversions on Xonvert, with 668 daily conversions on average. The entire conversion pipeline runs in a sandboxed WebAssembly environment for maximum security and performance.
Advantages of P7B over PEM
There are strong reasons to convert PEM to P7B:

PEM to P7B: Quality Comparison
When converting from PEM Certificate to P7B Certificate Chain, the conversion is lossless, meaning every bit of data is preserved exactly as in the original. PEM Certificate retains all original data. Converting to P7B Certificate Chain adds no further quality degradation since it uses lossless compression. Xonvert selects parameters that maximize quality for the target format. For professional use, quality assurance is critical. Xonvert's PEM Certificate to P7B Certificate Chain pipeline has been tested against reference implementations to ensure output meets certificate industry standards.
Certificate format conversion from PEM Certificate to P7B Certificate Chain re-encodes the cryptographic certificate data into a different container structure. The underlying X.509 certificate data, public keys, and chain information remain cryptographically identical. This is required when different servers, tools, or platforms expect certificates in specific formats.
The PEM to P7B conversion applies format-appropriate algorithms to ensure maximum data fidelity. Headers: -----BEGIN CERTIFICATE----- / -----END CERTIFICATE-----

PEM to P7B FAQ
Can I convert password-protected PEM files?▼
Encrypted or DRM-protected files cannot be converted. You'll need to remove protection first using the original software.
Can I convert multiple PEM 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 PEM file be deleted after conversion?▼
No. Your original PEM 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.
