Adding image & PDF compression

It’d be useful to have built-in options in OpnForm for handling compression regarding images and PDFs. For images, the ability to choose between a lossless or compressed format with the ability to configure on how much the Images should he compressed (1-100) would help a lot with managing file size. It’d also be great if we could decide whether to keep or strip metadata. On top of that, having support for lossless PDF compression would make the tool even more complete.
