This program converts previously base64-encoded PNG pictures back to actual PNG pictures that you can see. Before conversion, it checks if the encoded data is valid. If the input base64 is invalid, you'll get an error. Also, with this program, you can create glitch PNGs by randomly changing letters and numbers in the base64 data. As PNG is compressed, changing a couple of symbols in its base64 encoding will create unexpected visual effects in the output PNG. Png-abulous!
Use this tool to decode Base64-encoded strings back into plain text. However, if the original encoded Base64 string represents binary data, such as an image, the decoded output will appear as a series of unintelligible characters. Thus, this tool is optimized for decoding Base64 strings that originated from plain text. To transform text to a Base64-encoded string, use our Tool for Encoding Plain Text to a Base64 String.
Base64 is a versatile encoding scheme primarily designed to represent binary data in an ASCII string format, ensuring its safe transportation and storage in text-based systems. While sometimes employed for plain text encoding to manage special characters or for obfuscation, it's crucial to understand that Base64 does not provide encryption or security. For users leveraging our online tool for Base64 decoding, always ensure that the content being decoded is from a trusted source, as decoding malicious or manipulated data can pose risks.

Almost all programming languages provides function for base46 decoding. php base64 decoding: base64_decoding($encoded_string)
Python base64 decoding: base64.b64decode(encoded_string)
Javascript base64 decoding: atob(encoded_string)
A certificate can be either distributed in its raw binary form or further encapsulated into a Privacy-Enhanced Mail (PEM) file which includes the base64 encoding of the DER binary message preceded by "-----BEGIN CERTIFICATE-----" and followed by "-----END CERTIFICATE-----". The PEM file is usually stored with .pem, .cer or .crt file extensions.
This tool converts a base64-encoded string back to a human-readable string. In base64 encoding, every 4 symbols get converted to 3 human-readable characters. This makes base64 a very ineffective encoding as it uses one third more memory to store the encoded data. This utility also supports multi-line base64 where each line is of a certain length. The base64 encoding consists of lowercase and uppercase English alphabet, numbers and two extra symbols. That is 26+26+10+2 symbols, which is 64. Stringabulous!
The hexadecimal transcription in ASCII of the bytes would increase the size by two when we want to represent binary data (an image, an executable) in a textual message, such as an email. The base64 encoding allows us to reduce this increase.
