Frequently Asked Questions
Does this work on Windows 10 and Windows 11?
Yes — our tool runs in any modern browser and works on Windows 10 and Windows 11 with no compatibility issues.
Can I use this instead of Adobe Acrobat on Windows?
For redaction, yes. Adobe Acrobat costs $25/month and requires installation. Our tool is free, browser-based, and creates equally permanent redactions.
Does it work with Microsoft Edge?
Yes — Microsoft Edge is one of the best browsers for our tool on Windows. It supports all features including WebAssembly PDF processing.
Is it safe to process sensitive documents on a shared Windows PC?
Yes — files are processed in your browser memory and never saved to any server. Once you close the tab, no trace of the document remains online.
