Encode images to Base64 format
Encode your Image to Base64 format using our fast and free online tool.
You can also decode your base64 encoded Image to Image using our Base64 Image Decoder Tool.
Simply Select your image and click on Encode Image to convert it to Base64 format.
- Base64 Decoder and Base64 Encoder are simple online tools that does exactly what
it says: decodes from Base64 encoding as well as encodes into it
quickly and easily. Base64 encode your data without hassles or
decode it into a human-readable format.
- Base64 encoding schemes are commonly used when there is a need to encode binary data, especially when that data needs to be
stored and transferred over media that are designed to deal with text. This encoding helps to ensure that
the data remains intact without modification during transport. Base64 is used commonly in a number of
applications including email via MIME, as well as storing complex data in XML or JSON.
- Base64 is an encoding algorithm that converts any characters, binary data, and even images or sound files
into a readable string, which can be saved or transported over the network without data loss.
- Base64 encoding schemes are commonly used when there is a need to encode binary data that needs to be stored
and transferred over media that are designed to deal with ASCII. This is to ensure that the data remain
intact without modification during transport.
What is Base64?
- Base64 is numeral system of base-64 which uses 64 digit set and can be represented by 6 bits. To learn more
about Base64, please visit Base64 Wikipedia page.
- From now on, you don't need to download any software for such simple tasks.
The particular choice of characters to make up the 64 characters required for Base64 varies between
implementations. The general rule is to choose a set of 64 characters that is both 1) part of a subset
common to most encodings, and 2) also printable. This combination leaves the data unlikely to be modified in
transit through systems such as email, which were traditionally not 8-bit clean.
- For example, MIME's Base64 implementation uses A-Z, a-z, and 0-9 for the first 62 values, as well as "+" and
"/" for the last two. Other variations, usually derived from Base64, share this property but differ in the
symbols chosen for the last two values; an example is the URL and filename safe "RFC 4648 / Base64URL"
variant, which uses "-" and "_".
Base64 is a generic term for a number of similar encoding schemes that encode binary data by treating it numerically and translating
it into a base-64 representation. The Base64 term originates from a specific MIME-content transfer encoding.
A Base64 ends with either = or == or any of the accepted Base64 digit [A-Za-z0-9+-]. The = is a padding that
indicates the number of actual bytes of data in the last three bytes.
How does base64 table look like?
- Simply select the image from your device that you want to convert to
base64 encoded form.
- If the image you provided is not corrupted then it will take you to a new page where you will find a
textarea containing the base64 encoded image data.
- You can directly copy it by clicking the copy text button.
- You can cross check it by pasting it in base64 decoder and
checking if it is the same image or not.
We will illustrate how Base64 encoding works by converting text
data, as it's more standard than the various binary formats to choose from. If we were to Base64 encode a string
we would follow these steps:
- Take the ASCII value of each character in the string
- Calculate the 8-bit binary equivalent of the ASCII values
- Convert the 8-bit chunks into chunks of 6 bits by simply re-grouping the digits
- Convert the 6-bit binary groups to their respective decimal values.
- Using a base64 encoding table, assign the respective base64 character for each decimal value.
What is data:image/png;base64?
data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64
encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document
(or within the HTTP protocol even).
