Sejda SDK is a task oriented PDF editor SDK library written in Java.
Sejda SDK offers a set of "ready to go" manipulations implemented using SAMBox, a PDFBox fork that we maintain, but you can also provide your implementation using iText, iText 5.x, PDFBox or any other PDF engine and configure Sejda to use it.
