Secure File Shredder
Overwrite files in memory using multiple passes of random data, zeros, and ones — implementing DoD 5220.22-M and Gutmann-inspired wiping patterns — then download the overwritten output. Use this before deleting cloud-synced or shared files to ensure the content cannot be recovered.
All processing happens locally in your browser. No data is uploaded.
⚠ Browser Security Note: This tool overwrites file data in memory and produces a wiped output file you can download and replace the original with. True disk-level overwrite requires OS-level tools (e.g.
shred, sdelete). This tool is most effective for files stored in cloud services (Google Drive, Dropbox) or temporary locations where you can replace the file content.

Understanding Browser-Based Shredding
What this tool does: Reads your file into memory, overwrites all bytes using the selected algorithm, then offers the overwritten file as a download. If you replace your original file with this output, the stored content is gone.
What this tool cannot do: Directly write to your disk sectors. True forensic-grade deletion requires OS tools:
• Linux/macOS:
• Windows:
Best for: Cloud-synced files (Google Drive, Dropbox, OneDrive), files shared on cloud storage, temporary files before account deletion, and situations where replacing file content is sufficient.
