Base-64 Bitmap Encoder

World's simplest bitmap tool

This is a free browser-based utility that encodes bitmaps to the base-64 encoding. The encoded output can also be split in lines of a certain length (for example, 80 characters). You also have an option to enable URL-encoding, that will append the URL scheme "data:" at the beginning of base-64 output data. Created by the graphics designers from team Browserling.

Base-64 Bitmap Encoder options

Base64 Length

Split Base64 in Fragments If you enable this option, then base64 output will be split in fragments of a certain length.

Fragment Size Fragment size (line length).

Data URI Scheme

Add Data URI Scheme Signature If you enable this option, then base64 output will have data: prefix added in front of it that will make it a valid Data URL.

What is a Base-64 Bitmap Encoder?

learn more about this tool

This online program converts a bitmap (an image with extension .bmp) to base64 encoded data. Base64 uses 64 different ASCII characters to represent binary data and is used for sending binary data (such as images, files, or music) over plain-text protocols (such as email). As base64 text can get megabytes and megabytes in length, then to improve its readability, you can split it in pieces of a certain length (in the options above). If this option is enabled, then every base64 fragment will be put on a new line. Additionally, you can add a data URI scheme signature in front of the base64 data, which will make it a valid inline data URL.
