What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format by converting it into a set of 64 characters, consisting of letters, numbers, and symbols. It is commonly used for encoding binary data, such as images or files, into a format that can be easily transmitted over text-based channels like email or HTML.
What is Base64 Decoding?
Base64 decoding is the process of converting data encoded in Base64 back to its original binary format. This involves reversing the encoding algorithm, which maps each group of 6 bits in the Base64 encoded data to a corresponding 8-bit byte in the original binary data. The resulting decoded data can then be used in its original form, such as an image or file.
How Does Base64 Decoding Work?
Base64 decoding works by taking a Base64-encoded string and converting it back to its original binary representation. The encoded data is divided into groups of four characters, each representing 24 bits. These 24 bits are then split into four groups of 6 bits, which correspond to specific characters in the Base64 character set. These characters are then mapped back to their 8-bit binary representations, and the resulting binary data is the decoded form of the original input.
What is Base64 Image Viewer?
The Base64 Image Viewer is an online program that allows users to decode and display photos encoded with the Base64 technique. It provides a straightforward and easy-to-use method for converting Base64-encoded picture data back into the original image format, allowing users to visualize data.
What File Formats Are Supported?
The supported image formats depend on your device and browser. The following image formats are supported in the vast majority of cases:
- PNG
- JPG/JPEG
- BMP
- GIF
- WebP
How Do I Use the Free Online Base64 Image Viewer?
- Simply enter the encoded Base64 image in the Input field.
- The decoded Base64 image will be displayed automatically.
Is Base64 an Encryption?
Base64 is not encryption; rather, it is an encoding scheme. Base64 is a reversible encoding method used to represent binary data as ASCII text for transmission over text-based channels, whereas encryption involves transforming data to make it unreadable without the proper decryption key. Base64-encoded data is easily reversed to its original form using the appropriate decoding algorithm, and it lacks inherent security or confidentiality.
Is it secure to use your Base64 Image Viewer?
Yes, because the images you decode are not saved on our servers, even temporarily.
Base64 Characters and Table
The set of 64 ASCII characters used in Base64 encoding consists of uppercase letters (A-Z), lowercase letters (a-z), digits (0-9), and two additional characters, typically “+” and “/”. The “=” character is also used for padding.
