Three small tools that work offline in your browser. Nothing is uploaded and you do not need an account.
File hash checker (SHA-256)
Get the SHA-256 fingerprint of any file and see what it really contains. Useful to verify a download or to spot a file with a fake extension. The file never leaves your device.
Compare two files
Choose two files. If their SHA-256 hashes match they are exact duplicates, whatever their names.
Remove location (GPS) from photos
Choose one or more photos. JPEG metadata (EXIF, XMP, comments) is removed without recompressing, so quality stays the same. Other image types are re-saved without metadata. Download the clean copies.
