Frequently Asked Questions
- What is a P7B file?
- A P7B (or .p7c) file is a PKCS#7 bundle: one or more certificates, usually a server certificate with its intermediate CA certificates, without any private key. Windows and some certificate authorities hand out certificate chains this way. Web servers such as nginx and Apache want PEM instead.
- What is the OpenSSL equivalent?
- openssl pkcs7 -print_certs -in bundle.p7b -out bundle.pem. Like OpenSSL, the output lists each certificate with a subject= and issuer= line before its PEM block.
- How do I convert P7B / PKCS#7 to PEM certificates?
- Upload your P7B / PKCS#7 file above, click Convert, and download the PEM certificates result instantly. No account or software needed.
- Is converting P7B / PKCS#7 to PEM certificates free?
- Yes. It is free and unlimited for files up to 5 MB, with no account required. Larger files get 3 free conversions per day; beyond that, credit packs start at $3 and credits never expire.
- Are my files stored or shared?
- No. Files are processed in server memory and deleted immediately after conversion. File contents are never written to disk or retained.
- Do I need to install anything?
- No software installation needed. OmniConvert runs in the browser — just upload, convert, and download.
