Need Uncompressed BMP Format?

BMP (Windows Bitmap) is an uncompressed image format. While outdated for most uses, some legacy software, embedded systems, and specialized applications specifically require BMP files.

Converting JPG to BMP creates uncompressed bitmap files for these specific use cases. The image is decompressed to raw pixel data.

How to Convert JPG to BMP

  1. Upload your JPG file - Select your image
  2. Confirm BMP output - BMP provides uncompressed bitmap format
  3. Download your file - Get your BMP file for legacy applications

Conversion happens in your browser-no software required.

Why Use BMP?

Legacy Software

Some older Windows applications and industrial software only accept BMP files. If your system specifically requires BMP, conversion is necessary.

Embedded Systems

Certain microcontrollers and display systems work with raw bitmap data. BMP's simple uncompressed format is easier to parse.

Technical Applications

Some engineering and medical imaging software uses BMP for its straightforward pixel format.

BMP Characteristics

  • Uncompressed - No data loss, but very large files
  • Simple format - Raw pixel data, easy to process
  • Windows native - Originated with early Windows
  • No transparency - Limited to solid backgrounds

File Size Warning

BMP files are dramatically larger than JPG:

  • A 500KB JPG might become 5-10MB as BMP
  • No compression means full raw pixel data
  • Ensure you have adequate storage space

Only use BMP when specifically required. For most uses, JPG or PNG are more efficient.

Works on Any Device

Convert JPG to BMP in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android

Pro Tip

If you need uncompressed images for editing, use PNG instead of BMP. PNG is lossless like BMP but much smaller due to compression. BMP is only necessary when software specifically requires it.

Common Mistake

Converting to BMP thinking it improves quality. Quality can't exceed the source. If your JPG is 85% quality, the BMP will contain that same 85% quality data in a larger file.

Best For

Legacy software requirements, embedded systems with specific format needs, and technical applications that only accept bitmap format.

Not Recommended

Don't use BMP for general storage, sharing, or web use. Files are 10-20x larger than equivalent JPG or PNG with no quality benefit. Use only when specifically required.

Frequently Asked Questions

Only if you have software that specifically requires BMP format-legacy applications, embedded systems, or specialized technical software. For normal use, BMP is unnecessarily large.

No. JPG compression already removed some data. Converting to BMP won't restore it. The image will look identical but in a larger file format.

BMP stores raw, uncompressed pixel data. A 1920x1080 image at 24-bit color takes about 6MB regardless of content complexity. JPG compresses this to kilobytes.

Standard BMP doesn't support transparency. Any transparent areas in your image will become solid color (usually white).

BMP preserves the image without further compression, but can't restore what JPG already removed. From an original uncompressed source, BMP would be better. From JPG, quality is identical.

Some legacy Windows applications, industrial control systems, certain scientific instruments, and embedded display systems. Modern software typically prefers PNG or JPG.

Yes. Modern macOS Preview can open BMP files. Despite being a Windows format, BMP is readable on any modern system.

No. PNG provides lossless compression at much smaller sizes. BMP's lack of compression wastes storage. Use PNG for lossless archiving.
