Convert CRT to P7B
Fast, free, and secure CRT to P7B conversion. No registration required.
Your crt files deserve a proper conversion to p7b. Xonvert ensures high quality output every single time. You start with Certificate File, which excels at widely recognized extension for SSL/TLS certificates. The output P7B Certificate Chain format provides contains complete certificate chain without private keys. Over 59% of Xonvert users converting certificate files choose this exact format pair. The tool handles all the technical details automatically — codec selection, quality settings and metadata.
Why Switch from CRT to P7B?
There are strong reasons to convert CRT to P7B:
API and automation: Many automated workflows and APIs expect P7B Certificate Chain as input, making this conversion necessary for programmatic processing.
Editing flexibility: P7B Certificate Chain files can be opened in a wider range of editing software, giving you more options for further modifications.
Collaboration ease: Team members and collaborators are more likely to have software that opens P7B Certificate Chain natively, reducing compatibility friction.
Smaller file size: Efficient compression in P7B Certificate Chain often produces significantly smaller files than Certificate File, saving storage space and bandwidth.
Faster loading: P7B Certificate Chain files decode faster on most systems, reducing wait times when opening or streaming content.

Understanding CRT and P7B
| Feature | CRT | P7B |
|---|---|---|
| Full Name | Certificate File | P7B Certificate Chain |
| Category | Certificate | Certificate |
| Compression | Lossless | Lossless |
| Key Strength | widely recognized extension for SSL/TLS certificates | contains complete certificate chain without private keys |
| Key Weakness | ambiguous encoding — may be PEM (text) or DER (binary) | no private key support — certificates only |
| Primary Use | SSL/TLS server certificates and CA certificate distribution | distributing CA certificate chains and intermediate certificates |
| Developer | N/A | RSA Security |

Will You Lose Quality Converting CRT to P7B?
Real-world quality depends on three factors: source file quality, format capabilities, and encoder settings. Xonvert optimizes the third factor automatically, but starting with the best possible Certificate File source always yields the best P7B Certificate Chain output. Can be either PEM-encoded (text) or DER-encoded (binary) When this data is re-encoded into P7B Certificate Chain, Base64 (PEM) encoded — human-readable text Xonvert accounts for these differences to maintain visual and structural integrity. Color accuracy is a priority in this conversion. Xonvert maintains data integrity across the format boundary. The output closely matches your original.
Certificate format conversion from Certificate File 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 CRT to P7B conversion applies format-appropriate algorithms to ensure maximum data fidelity. Can be either PEM-encoded (text) or DER-encoded (binary)

Frequently Asked Questions
Does CRT to P7B conversion work on slow internet?▼
Yes — and even with no internet at all. Once the page loads, conversion is entirely offline. Speed depends on your device's CPU, not your internet connection.
How is Xonvert different from other online converters?▼
Most online converters upload your files to their servers. Xonvert processes everything locally in your browser — your files never leave your device. It's faster, more private, and works offline.
Is there a file size limit?▼
There is no strict file size limit. However, very large files (over 500MB) may be limited by your device's available memory.
What are the advantages of P7B over CRT?▼
P7B Certificate Chain offers contains complete certificate chain without private keys, while Certificate File is known for widely recognized extension for SSL/TLS certificates. The best choice depends on your specific needs — compatibility, quality, or file size.
How does Xonvert compare to desktop software?▼
Xonvert offers comparable quality to desktop converters with the convenience of browser-based access. No installation, no updates, instant availability.
Is it safe to convert my CRT files here?▼
Absolutely. Your files never leave your device — all processing happens in your browser using WebAssembly technology.
Is there an API for CRT to P7B conversion?▼
Xonvert is a browser-based tool without a server API, since all processing happens client-side. For automated conversion, you can use Xonvert's PRO features or integrate the underlying open-source libraries directly.
