Frequently Asked Questions
How does NEOKYRU compare to iLovePDF for this tool?
Unlike iLovePDF which transmits your private documents to third-party cloud servers with strict file size limits and paywalls, NEOKYRU runs 100% client-side in your browser via WebAssembly. Your files never leave your computer, there are no file size caps, zero queue wait times, and it is 100% free with no registration required.
Can someone remove the black boxes to read the text beneath?
No. Our redaction engine permanently erases the vector text glyphs from the PDF binary structure.
