Common questions
Will the quality of my document be affected?
For merge, split, rotate, and organize tasks, page content and vectors are preserved losslessly. For compression, you have full control over structural optimization versus image downsampling.
Can I cancel processing if I change my mind?
Yes. You can hit Cancel at any time to immediately terminate the worker and clear all buffered data from memory.
