As answered by people managing mat2 and Barecopy.
Barecopy's answer:
Privacy-conscious professionals who share documents and photos: lawyers, journalists, HR and recruiters, real-estate and finance staff, consultants, and anyone in a corporate environment who needs to strip author names, company info, edit history, or GPS location before sending a file out. The corporate-network-friendly, no-upload design specifically targets people whose employers block cloud tools.
Barecopy's answer:
Barecopy grew out of a real, recurring problem: hidden metadata leaking sensitive information — an author's name, a company, revision history, or the GPS coordinates baked into a photo. Existing online cleaners solved this by uploading your file to their servers, which defeats the purpose. Barecopy was built on the opposite principle — your files never leave your machine — after CDN-blocking corporate networks repeatedly broke server-dependent tools. It's a deliberately simple, self-hosted, single-page app so that the privacy guarantee is provable, not just marketing.
Barecopy's answer:
Barecopy does 100% of its work in your browser. Files are read, analyzed, and cleaned locally — nothing is ever uploaded to a server. Most "metadata remover" tools online quietly upload your document to their backend to process it, which is exactly the wrong trust model for a privacy tool handling sensitive files. Barecopy's entire app is a single static page with self-hosted libraries and zero external requests, so even on locked-down corporate networks (which block CDNs) it works — and there's no server that could leak your data.
Barecopy's answer:
Barecopy is used by privacy-conscious individuals and professionals across legal, journalism, HR, and corporate roles. By design it processes files entirely on the user's device and collects no data, so it keeps no customer list.

Metadata Cleaner which makes use of Mat2. Source: over 3 years ago
Otherwise you're maybe better off copying the files first and sanitising them before you create the tar. Maybe something like MAT can help here or you could write a script that performs some preset actions to remove or replace any... Source: almost 4 years ago
