Upload a .jar, browse entries, edit text files, save & download the updated archive.

View manifest and list all entries with sizes.

Combine multiple .jar files into one archive.

Convert every .class into readable .java source, preview the code, and download a .zip.

Search all classes, methods, fields and string literals inside a .jar.

Unpack a .jar to .zip — all files, resources only, or classes only.
