About This Tool
Import digital signing identities with our free online certificate import tool. Load your PKCS#8 or PKCS#12 (.p12/.pfx) signing certificates for use in browser-based PDF signing workflows.
Upload your signing certificate file and enter the password to decrypt. The private key is loaded into browser memory for signing operations but is never stored persistently or transmitted anywhere. Supports certificates from Adobe Acrobat, commercial CAs, and enterprise PKI systems.
All certificate import happens locally in your web browser. Your private key exists only in memory during your session and is discarded when you close the browser. Maximum security for your signing credentials.
Perfect for using existing enterprise certificates, importing commercial signing credentials, loading backup certificates for signing, or integrating with organizational PKI. Works with standard PKCS#12 files from certificate authorities and enterprise certificate management systems.
