Fast workflow
Designed to reduce friction with direct upload, quick processing, and one-click export.
Open File Shredder, add your file, then choose the target output and run conversion.
This tool is optimized for security utilities and works best with * as inputs.
When processing completes, download the result in * and verify quality before sharing.
File Shredder is a privacy-first utility for fast security utilities. It helps you move from * to * with consistent output quality.
Designed to reduce friction with direct upload, quick processing, and one-click export.
Files are handled in an isolated processing flow with minimal retention and clear user controls.
Outputs are tuned for real use cases across *.
A predictable sequence keeps conversion stable across devices and file sizes.
File Shredder accepts * and exports *.
The pipeline is designed for privacy-first processing with clear user control over inputs and outputs.
Use high-quality source files, choose the closest matching target format, and avoid repeated reconversion cycles.
File Shredder follows a deterministic conversion flow so results are repeatable and easier to troubleshoot when a file behaves unexpectedly.
Generate a random-data file of the same size to overwrite your original. 100% local.
All random data is generated locally in your browser using crypto.getRandomValues() — the same cryptographic RNG used by banking systems. Your file contents are never read, uploaded, or transmitted. Only the file size is checked.
Creates a same-size file filled with cryptographically secure random bytes using the browser's crypto.getRandomValues() API. The generated file can then be used to overwrite your original file on disk, making data recovery through forensic tools impossible. Unlike simple deletion (which only removes the file reference), overwriting replaces the actual data blocks on the storage device.
When you need to securely erase a file before selling a device, disposing of storage media, complying with data-destruction policies (NIST 800-88), removing sensitive documents after they're no longer needed, or preparing a drive for decommissioning.
