This is a free and fast online utility that decodes base-64 bitmaps and turns them back into visible bitmaps. You can load regular continuous base-64 text, base-64 data with the data URI scheme (data:image/bmp) at the beginning, and multi-line base-64 chunks, and convert it into a downloadable BMP file. Created by graphics designers from team Browserling.

This free online browser-based program decodes base64 data that contains a previously base64-encoded bitmap image (an image with a .bmp extension). Once decoded, the bitmap is displayed in the output preview area. The base64 encoding is a neat way to represent bitmaps (that are binary files) in the form of a character sequence (that are text files). Transmitting bitmaps as plain text is very useful, as you don't have to deal with binary encoding problems, such as null bytes and endianness of the data. An encoded base64 bitmap uses 64 different 7-bit basic ASCII characters. This tool accepts base64 data of any length, and it also handles optional line breaks every 76 characters or fewer (as specified in MIME RFC). If you're working with base64 data URLs, then it can also decode them. Bmp-abulous!

In this example, we load base-64 data that's encoded in base-64 encoding. This data contains a bitmap image. When it's decoded, we find that it's a bitmap image of a polar bear, and the size of the image is 200×175.
In this example, the input base64 string has the uniform resource identifier (URI) scheme as a prefix. We know that this string contains a bitmap format image because the MIME type says "image/bmp". When this base64 string is converted back to a visible image, we see that it's a drawing of a camping tent and mountains.

We're Browserling — a friendly and fun cross-browser testing company powered by alien technology. At Browserling, we love to make people's lives easier, so we created this collection of online bitmap tools. Our BMP tools have the simplest possible user interface and work directly in your browser without downloads or installations. You can use them to edit bitmap images, change BMP bit depth and colors, resize bitmaps, create transparent BMPs, work with bitmap pixels and byte arrays, and much more. Behind the scenes, our bitmap tools are powered by our web developer tools that we've created over the years. Check them out!
