PDF-Utility-Java

Very often we need to decrypt, merge & split sensitive pdf files (e.g.; payslips, tax return, medical report etc) into one big pdf for an easy upload. While using similar free online or paid tool may not be safe and could cause fraud in the future. Hence this little java utility can be used by developers locally to do the followings.

• Merge many pdf files into a single pdf
• Split many pdf files into a many pdf
• Decrypt many pdf files given a password

Usage

git clone https://github.com/subratamazumder/pdf-utility-java.git

cd pdf-utility-java

./gradlew clean build jar

java -jar ./build/libs/pdf-utility-2.0-SNAPSHOT.jar MERGE /my/directory/which/has/pdffiles
java -jar ./build/libs/pdf-utility-2.0-SNAPSHOT.jar DECRYPT /my/directory/which/has/pdffiles password
java -jar ./build/libs/pdf-utility-2.0-SNAPSHOT.jar DECRYPT /my/directory/which/has/pdffiles password
java -jar ./build/libs/pdf-utility-3.0-SNAPSHOT.jar SPLIT /my/directory/which/has/pdffiles <splitAtPage, e.g.; 1>
