- JKS to GPG
Convert a file to JKS
To convert other file formats to the "Security Certificate Store" file type, you need software like Java Keytool or a similar tool.
- CER to JKS
- BIN to JKS
- PEM to JKS
- DER to JKS
- KEY to JKS
- P7S to JKS
- PFX to JKS
- ENC to JKS

About JKS files
The .JKS file is a proprietary Java KeyStore container used exclusively by the Java Development Kit (JDK) to store cryptographic keys, certificates, and certificate authorities. While essential for Java-based applications (like Tomcat or Jetty), the .JKS format presents significant interoperability challenges in modern DevOps environments. Being a binary proprietary format, it is unreadable by standard text editors and incompatible with non-Java servers like Nginx or Apache HTTP Server, which typically require Base64-encoded PEM or CRT files. Furthermore, since Java 9, the JDK itself warns users to migrate away from JKS in favor of the industry-standard PKCS12 format due to its broader support. To overcome these limitations - such as using a Java-generated certificate on an AWS Load Balancer or an Apache server - users must convert the .JKS file. For web server deployment, convert to PEM (separate key and certificate files). For cross-platform portability between Windows and Java, convert to P12 or PFX. Our tools allow you to easily inspect and manage these conversions without navigating complex command-line syntax.
Convert.Guru analyzes your JKS file, detects the exact format, and lets you read the text inside.
Users also converted KEYSTORE, CERT, TXT, PDF, JPG, PFX, SSL, P12, P7S, ZIP, CRT, JSX and PNG files.
The JKS Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our JKS converter.
