About this tool
Check a PDF for metadata, earlier versions saved inside it, scripts, attached files, comment authors and text hidden under black boxes, then save a clean copy.
- Does a black box over text hide it?
- No. Text under a drawn box is still in the file, and anyone can copy or search it. The check finds it, and Redact removes it for good.
- Is it free?
- Yes. Sign Veli’s PDF tools are free to use and need no account.
- Are my files uploaded?
- No. The tool runs entirely in your browser, so your file never reaches Sign Veli’s servers.
