Base64 Encode & Decode

Convert text or a small file to Base64 and back — UTF-8 safe, with a URL-safe option for links and filenames.

🔒 Runs privately in your browser — nothing is uploaded
📎 Encode a file instead
🛡️ Your text and files are handled only in your browser. They never touch a server — not even ours.

How to encode and decode Base64 online

  1. Choose Encode to turn text into Base64, or Decode to turn Base64 back into text.
  2. Paste your text or Base64 into the box — or click "Encode a file instead" to convert a small file.
  3. Tick URL-safe if you need the result for a URL or filename.
  4. Copy the result. Everything is processed privately and never uploaded.

Why use a Base64 converter?

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.

Common uses

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.

Frequently asked questions

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.
