Hexloom's answer
JavaScript that runs in your browser. The PDF engine is the open-source pdf-lib library, and the site is served by Cloudflare.
Hexloom's answer
Choose it for a quick look-and-clean of Word, Excel, PowerPoint and PDF files with nothing to install and no file sent to a server. If you need to redact visible text, remove embedded files or macros, or handle the old .doc, .xls and .ppt formats, it is not the right tool, and the page says so.
Hexloom's answer
It pairs a plain "found in your file" report with the cleaning itself, and it runs in your browser, so the file is not uploaded; you can confirm that in the Network tab. It also lists what it does not remove (names in the body text, headers, footers, the file name, hidden rows and slides), so you know what to check yourself.
Hexloom's answer
People who send files outside their organization and do not want their name, comments or tracked changes to travel with them: freelancers and consultants sending proposals, small agencies, recruiters and HR teams sharing resumes, paralegals and small law offices, and journalists.
Hexloom's answer
Hexloom Labs builds small browser tools that work on your files without uploading them. Doc Scrubber covers one job: showing what a Word, Excel, PowerPoint or PDF file carries about its author, then giving you a copy without it. The tool and this text were made with AI assistance, and its behaviour is checked by running it against sample files.
