Convert Bitmap images (DIB) online for free
The converter easily converts your DIB bitmaps to various formats - free and online. No Microsoft Paint or or other Raster Image software needed.
The converter also works in reverse, so you can convert other "Device-Independent Bitmap" formats to DIB without using software like Microsoft Paint or a similar tool.
A .dib (Device-Independent Bitmap) is a legacy raster image format created by Microsoft to ensure visual consistency across different devices, graphics cards, and color spaces. Structurally, it is nearly identical to a standard bmp file, but it lacks the standard 14-byte bitmap file header, instead relying directly on its internal DIB header. For more background, see the BMP file format Wikipedia page.
Typically, you can open .dib files natively using Microsoft Paint, Adobe Photoshop, or dedicated image viewers like ACDSee. However, the format poses serious limitations in modern workflows. .dib files are strictly uncompressed, meaning they generate massive file sizes that consume unnecessary disk space. Because it is a legacy format, it is largely unsupported by modern web browsers, mobile devices, and most cloud preview tools.
To solve these problems, you need to convert this file format. For web deployment or easy sharing, convert your .dib to webp or jpg to drastically reduce file sizes. If you need to preserve crisp edges without compression artifacts, convert to png. Just drag and drop your file here to analyze and convert it securely right in your browser - free, online, and without installing clunky software.

To convert RAW or AI files to DIB, try Microsoft Paint or another comparable tool in the "Raster Image Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DIB converter.
