Base64 Online Encoding and Decoding | Base64 Encryption and Decryption

Please enter the characters to be encoded/decoded in the first text box above.

Language	Base64 Encoding	Base64 Decoding
Java	base64 = new BASE64Encoder().encode(str.getBytes());	str = new String(new BASE64Decoder().decodeBuffer(base64));
JavaScript	base64 = btoa(str); // IE 10- requires base64.js and does not support Chinese characters or var s = CryptoJS.enc.Utf8.parse(str); base64 = CryptoJS.enc.Base64.stringify(s); // Requires CryptoJS	str = atob(base64); // IE 10- requires base64.js and does not support Chinese characters or var s = CryptoJS.enc.Base64.parse(base64); str = s.toString(CryptoJS.enc.Utf8); // Requires CryptoJS
PHP	$base64 = base64_encode($str);	$str = base64_decode($base64);
C#/.NET	byte[] bytes = System.Text.Encoding.UTF8.GetBytes(str); base64 = System.Convert.ToBase64String(bytes);	byte[] bytes = System.Convert.FromBase64String(base64); str = System.Text.Encoding.UTF8.GetString(bytes);
Python	import base64 base64 = base64.b64encode(str)	import base64 str = base64.b64decode(base64)
Perl	use MIME::Base64; $base64 = encode_base64($str);	use MIME::Base64; $str = decode_base64($base64);
Golang	import b64 "encoding/base64" ... base64 := b64.StdEncoding.EncodeToString([]byte(str))	import b64 "encoding/base64" ... str := b64.StdEncoding.DecodeString(base64)
Ruby	require "base64" base64 = Base64.encode64(str)	require "base64" str = Base64.decode64(base64)
MySQL/MariaDB	SELECT TO_BASE64(str); // The argument can also be a column	SELECT FROM_BASE64(base64); // The argument can also be a column
PostgreSQL	SELECT encode(str, 'base64');	SELECT decode(base64, 'base64');
Linux Shell (using test as an example)	$ echo test \| base64 // dGVzdAo=	$ echo dGVzdAo= \| base64 -d // test

Implementation Methods in Various Languages Advanced Settings

Settings (We use cookies to remember your advanced settings. These cookies are not logged or used for tracking)

Character Set Encoding

UTF-8 GB2312

Set the character set encoding. GB2312 cannot use the hexadecimal output function.

Auto Encode/Decode

Off Auto Encode Auto Decode

Set whether to automatically encode or decode when the content of the original text box changes.

Encoding/Decoding Hotkeys

Ctrl + Enter Enter

Set the hotkeys for encoding/decoding in the original text box. If one is set, the other will be used for new lines.

Action After Pressing Hotkey

Encode Decode

The action to perform after pressing the above hotkey.

Decoding Output Format

Text H \x \u &# {...}

Add spaces for non-text output

Set the format of the output after Base64 decoding.
If the character set encoding is set to GB2312, this setting will be invalid.
With spaces: \u5728\u4F7F\u7528 → \u5728 \u4F7F \u7528

Encoding Input Format

Text H {...}

Set the format for Base64 encoding input.
If the character set encoding is set to GB2312, this setting will be invalid.

Encoding Output Format

Plain Text URL Encoding

Set the format for Base64 encoded output, with URL encoding performed using the `encodeURIComponent` function.

Encoding Symbol Replacement

Replace + with

Replace / with

Replace = with

Replace during decoding as well

Replace special symbols in the encoding result ( +, /, =) with other content.
Replace during decoding: Before decoding, apply the selected replacement rules in reverse to the text to be decoded.
