Base64 to BMP Decoder: Convert Base64 Images to BMP

Do you have a Base64-encoded image that you want to convert to a BMP format? If so, you can use this tool to easily decode and save your image as a BMP file.

What is Base64?

Base64 is a method of encoding binary data into ASCII characters to facilitate data transfer and storage.

What is Base64 Decoding?

Base64 decoding, at its core, is the process of converting Base64-encoded data back to its original binary format. The encoding scheme is reversed in this process, and characters from the set of 64 ASCII characters are transformed into binary representations. Base64 decoding recovers the original data and allows you to access, read, and use it as intended.

How Does Base64 Decoding Work?

Base64 decoding works by mapping characters from Base64-encoded text back to their binary values. The original binary data is then recreated by combining these binary values. The encoded data is returned to its pre-encoded state after this reverse transformation, ready for processing, storage, or transmission.

What is BMP?

The BMP file format, also known as bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device (such as a graphics adapter), especially on Microsoft Windows and OS/2 operating systems.

What is the Base64 to BMP Converter?

A Base64 to BMP Converter is a program that converts a Base64 encoded string into a BMP image. Simply paste your Base64 encoded string into the tool’s input box, and it will convert it to a BMP picture for you.

How Do I Use the Online Base64 to BMP Image Decoder?

1. First, paste the encoded Base64 image.
2. No need to press a button, wait until Base64 is decoded. For large images this may take longer.
3. The decoded BMP image will automatically appear in the Output box.
4. If you want, you can download the result using the Download button.

How does the Base64 to BMP Converter work?

The Base64 to BMP Converter decodes Base64-encoded data by using the Base64 encoding algorithm in reverse. It takes the encoded string as input and converts it to the image’s original binary data. This method retrieves and displays the image in its visual form.

Why would I need to convert Base64 to BMP?

Because there are cases where it is not necessary or possible to upload a Base64 encoded image. In addition, Base64 images are unintelligible to the human brain and their size is larger.

Is it secure to use your Base64 to BMP Converter?

Absolutely. Our program operates entirely on the client side, which means all the conversion processes occur within your browser. No data is sent to our servers, ensuring that your information remains under your control and confidential throughout the conversion process.

Base64 Characters

Uppercase letters (A-Z), lowercase letters (a-z), digits (0-9), and two additional characters, typically “+” and “/”, comprise the set of 64 ASCII characters used in Base64 encoding. When the length of the binary data is not a multiple of three bytes, the “=” character is also used for padding.
