Secure File Shredder – Frequently Asked Questions (FAQ)

What is a Secure File Shredder?

A Secure File Shredder is a tool that overwrites files with random data multiple times so that the original content cannot be recovered.

How does the file shredder work?

The tool uses the File System Access API to let you select a file, then overwrites its content with random data for the specified number of passes.

Is this tool free and client-side?

Yes, it is completely free, and all operations occur locally in your browser.

Will shredding the file make the original content unrecoverable?

Yes. Overwriting the file with random data multiple times makes it virtually impossible to recover the original content.

What if the file is too large?

Shredding large files may take longer since the tool processes the file sequentially. Please be patient.

Does the tool delete the file after shredding?

The tool overwrites the file content but does not automatically delete the file. You can manually delete the file afterward if desired.

Is secure deletion guaranteed?

Multiple overwrite passes make recovery highly unlikely, but no method is 100% foolproof on every storage device.

Which browsers support this tool?

The File System Access API is supported in Chrome, Edge, Opera, and Brave. It requires a secure context (HTTPS).

Do I need to grant special permissions?

Yes. The tool will prompt you to grant access to the selected file via the File System Access API.

Is my data transmitted to a server?

No. All shredding operations occur locally within your browser; your file is never uploaded.
