Frequently asked questions
Which hash should I use?
SHA-256 for general use. SHA-512 if you need more bits. MD5 and SHA-1 are deprecated for security but fine for non-security checksums.
Why not use MD5 for passwords?
MD5 is fast — bad for passwords. Use bcrypt, scrypt, or argon2 (slow by design).
Are these the same hashes as command-line tools?
Yes. Output matches sha256sum and similar tools.
Are my files really not uploaded?
Correct. Every conversion in this tool runs in your browser using JavaScript and the local file APIs. There is no server-side processing, no file upload, no temporary storage, and no log of what you converted. You can verify this by opening your browser's network tab while converting — the only traffic is loading the page itself.
Do I need an account or to install anything?
No. Open the page, drop your file, download the result. No signup, no email, no extension, no app.
Is there a file-size limit?
Not from us. The practical limit is your device's memory — browser tabs typically handle files in the hundreds of megabytes range without issues. Very large files may take longer to process on phones than on laptops.
