How can I reduce the size of a jar file?
Obfuscators such as Proguard can often reduce the size of jar files considerably. Besides making the application harder to reverse engineer they can typically manipulate the byte code in a way that makes it smaller without affecting the functionality.
How do I compress a large file in Unix?
Both Linux and UNIX include various commands for Compressing and decompresses (read as expand compressed file). To compress files you can use gzip, bzip2 and zip commands. To expand compressed file (decompresses) you can use and gzip -d, bunzip2 (bzip2 -d), unzip commands.
How do I shrink a file in Linux?

Is jar file compressed?
Items stored in JAR files are compressed with the standard ZIP file compression. Java also has an archive format called Pack200, which is optimized specifically for Java class bytecode and can achieve over four times greater compression of Java classes than ZIP alone.
How do I turn a folder into a jar?

Is jar a tool?
jar is a general-purpose archiving and compression tool, based on ZIP and the ZLIB compression format. However, jar was designed mainly to facilitate the packaging of java applets or applications into a single archive.
How to reduce the size of a JAR file?
Obfuscation typically reduces jar file size by a respectable factor. You may want to try tools like Proguard (open source) and similar. Just another nice trick, usually using the unnamed package, which is deleting the name (< default> will appear), also decreases the jar size.
Are there any tools to compress LINUX files?
There are a number of tools that you use to compress files on Linux systems, but they don’t all behave the same way or yield the same level of compression. In this post, we compare five of them. There are quite a few commands on Linux for compressing files.
What’s the best way to compress a single file?
You can use tar to compress a single file as easily as a group though this offers no particular advantage over using gzip directly. To use tar for this, just identify the file as you would a group of files with a “tar cfz newtarfile filename” command like this:
