Why The Size Of Base64 encoded String Is Larger Than The Original
1 Answer Sorted by 46 just wondering why Because Base64 has fewer meaningful bits per byte than a binary data format usually 6 instead of 8 This is specifically so it can survive various textual transformations that binary data would not Wikipedia s page has a good diagram showing this
What Type Of Encoding Can I Use To Make A String Shorter , There is no encoding that reduces size Encodings are just mappings of bits to the character they represent That said ASCII is a 7 bit character set encoding that is often stored in 8 bits of space If you limit the ranges that you accept you can also weed out the control characters
Base64 What Is The Worst Possible Increase In Space Usage
Base64 encodes each set of three bytes into four bytes In addition the output is padded to always be a multiple of four This means that the size of the base 64 representation of a string of size n is ceil n 3 4 So for a 16kB array the base 64 representation will be ceil 16 1024 3 4 21848 bytes long 21 8kB
What Is Base64 Encoding And Why Is It Necessary , This in theory allows you to create another encoding that will use a bit less memory than base64 Such encodings actually exist for example base85 made in Adobe It is more memory efficient because it encodes 4 bytes of original data into 5 characters
Base64 Encoding Explained What It Is And Why You Need It
Base64 Encoding Explained What It Is And Why You Need It, Base64 is a binary to text encoding scheme that represents binary data in an ASCII string format It is commonly used in computer systems to transmit data over channels that can handle only

Base64 Wikipedia
Base64 Wikipedia Base64 encoding causes an overhead of 33 37 relative to the size of the original binary data 33 by the encoding itself up to 4 more by the inserted line breaks Design The particular set of 64 characters chosen to represent the 64 digit values for the base varies between implementations
Base64
A Base64 encoder starts by chunking the binary stream into groupings of six characters 100110 111010 001011 101001 Each of these groupings translates into the numbers 38 58 11 and 41 If the size of the original data in bytes is a multiple of three everything works fine If it is not there may be empty bytes For proper encoding How Base64 Encoding Works Lifewire.
