Hi Product Hunt 👋 I'm Safa, the maker of Exposift.
I built it after noticing how often files leave our hands with more inside than we meant to share: tracked changes, comments, author metadata, speaker notes — and the classic trap, a black box drawn over text that is still selectable underneath.
What Exposift does:
• Analyzes PDF, DOCX, XLSX and PPTX files and shows what it found and why it matters
• You decide what stays and what goes
• Removes the selected content for real (the text is deleted from the file, not just covered)
• Then re-reads the cleaned file with a separate reader to verify the values are gone
• Everything runs locally in your browser — files are never uploaded
• Free and open source (MIT)
Honest limits: no tool can guarantee complete protection, so please always review the final document before sharing it. I haven't yet verified every output in every desktop app (Word, Excel, PowerPoint, Acrobat), and feedback on edge-case files is very welcome.
Try the live demo, and tell me which file types or checks you'd like to see next. Thank you! 🙏
