Frequently asked questions
Are private details detected automatically?
No. Select every area yourself. Private details outside those areas may remain, so review the output.
Does the PDF keep text and signatures?
Every page is rasterized. Searchable and selectable text, digital signatures, forms and links are not preserved. The original file is unchanged.
How do resolution and file size change?
PDF output uses the selected resolution and may be larger than the original. Processing stops at memory limits. Image output is PNG.
