Demo only - no files are actually uploadedFile Shredder uses military-grade fragmentation combined with randomization techniques. Files are split into encrypted chunks with variable sizes, shuffled order, and optional padding. Without the extension, reconstructing the original file is virtually impossible.
The shredded fragments are stored locally in your browser's storage using IndexedDB. Nothing is ever uploaded to any server. Important: The original file remains in its original location and must be manually deleted for complete security.
No. File Shredder creates encrypted fragments of your files but does NOT delete the originals. After shredding, you must manually delete the original file and empty your trash/recycle bin to ensure the unencrypted version is completely removed from your system.
If you uninstall the extension, the fragmented chunks remain in your browser storage but become inaccessible. Make sure to download any important files before uninstalling.
