Is this base converter free?

Yes, completely free! No sign-up required, no usage limits, and 100% client-side processing means your data never leaves your browser.

What bases are supported?

We support 7 bases: Binary (Base 2), Octal (Base 8), Decimal (Base 10), Hexadecimal (Base 16), Base32, Base58, and Base64.

Base58 is commonly used in cryptocurrency addresses (like Bitcoin) to avoid confusing characters like 0, O, I, and l.

Base32 is often used in DNS entries, contact information (vCard), and systems that require case-insensitive encoding.

100% secure! All conversions happen locally in your browser using JavaScript. Your data is never sent to any server.
