logically decoding to and re-encoding should give you exactly the same ..
what OS are you running and what rev of FMP14?
Not sure what the client is running - just started working with them today.
I'm macOS Sierra and Windows 7 Pro.
FileMaker is 14.0.6.

Could you provide test file before/after?
So we could look for differences?
With MBS Plugin we have functions to load/save pictures, so maybe if we can detect the issue we can fix them automatically?
3 container fields.
Left column - original images
Middle column - Originals Base64Encoded and then decoded
Right column - Originals, reserved in Photoshop.
If you save as PDF the problem is pretty clear.
