Convert text or a small file to Base64 and back — UTF-8 safe, with a URL-safe option for links and filenames.
Base64 turns any text or binary data into plain ASCII letters, so it can travel safely through systems that only handle text — data URIs, JSON payloads, email attachments, JWT tokens and config files. Decoding does the reverse, letting you read what a Base64 string actually contains.
Developers embed small images as Base64 data URIs, inspect JWT tokens, and debug API payloads. This tool is UTF-8 safe, so emojis, Hindi and other Indian-language text encode and decode correctly. Because everything runs privately in your browser, it's safe even for tokens and sensitive strings.
Is my data uploaded to a server?
No. All encoding and decoding happens inside your browser, so your text and files are never uploaded — completely private.
Why did my decode fail?
Decoding fails if the input isn't valid Base64 — a stray space, a missing character, or it was never Base64 to begin with. The tool shows a friendly message so you can check and try again.
Does it handle emojis and Indian languages?
Yes. Encoding and decoding are UTF-8 safe, so emojis and Hindi, Tamil, Bengali and other scripts round-trip correctly.
