FAQ
How do I verify a downloaded file?
Upload the file to get its MD5 and compare with the official value: a match means intact, otherwise it may be corrupted or tampered.
Is computing large files slow?
Limited by browser memory, files up to a few hundred MB are recommended; computation is local and depends on device performance.
Will my file be uploaded?
No, files are read and hashed locally without any network transfer.
