BMP File

File extension	.BMP, .RLE, .DIB
Category	Image File
Description	May be the simplest file format, BMP was developed jointly by Microsoft and IBM. That is why it is widespread on Windows platform. This extension is characterized a raster graphic format which is recognized by many programs today. In comparison with other bitmap formats, JPEG and GIF, BMP keeps color data for each pixel in the image and doesn't compress images to decrease a file size. That is what makes it perfect file format for printable images.

JPG File

File extension	.JPG, .JPEG, .JPE, .JFIF, .JFI
Category	Image File
Description	JPG is the file format for images made by digital cameras and spread throughout the world wide web. Saving in JPG format an image loses its quality, because of the size compression. But at the end you have a much smaller file easy to archive, send, and publish in the web. These are the cases when an image's size matters more than image's quality. Nonetheless, by using professional software you can select the compression degree and so affect the image's quality.

BMP to JPG Converter — Frequently Asked Questions ▼

What is a BMP file?

BMP (Bitmap) is Microsoft's uncompressed raster image format, native to Windows. BMP files store raw pixel data with minimal compression, making them very large — a 1920×1080 BMP in 24-bit color is about 6 MB, compared to under 1 MB for an equivalent JPEG. BMP is the default format for Windows Paint and is produced by some older scanners, screen-capture tools, and industrial imaging systems.

How do I convert BMP to JPG online?

Upload your .bmp file to the CoolUtils converter. The converter compresses the bitmap and writes a standard JPEG. Download the .jpg when done. No software installation required. Files up to 50 MB are supported.

How much smaller will my file be after converting BMP to JPG?

Typically 90–98% smaller, depending on image content and JPEG quality setting. A 6 MB BMP screenshot becomes 200–500 KB as a JPEG at quality 85. Images with gradients or photos compress more than flat-color graphics or screenshots. For lossless conversion (no size reduction), convert to PNG instead.

Does converting BMP to JPG reduce image quality?

Yes — JPEG is lossy compression. At quality 80–90, the difference is invisible to most viewers for photographs. For images with sharp text, thin lines, or flat colors (logos, diagrams, screenshots), JPEG compression introduces visible artifacts around edges. For those use cases, PNG is a better target format.

What are common reasons to convert BMP to JPG?

Email attachment: BMP files are blocked by many email servers due to their size. Web upload: websites and content management systems often reject BMP files or enforce size limits. Social media: Instagram, Twitter, Facebook, and LinkedIn do not accept BMP uploads. Storage: converting a BMP archive to JPEG reduces disk usage significantly. Mobile: most Android and iOS apps cannot open BMP files.

Why does Windows Paint save images as BMP by default?

Windows Paint has saved to BMP by default since Windows 1.0 in 1985. It is the simplest pixel-storage format — no compression, no metadata complexity, directly maps pixel colors to bytes. Newer versions of Paint support PNG and JPEG natively, but older systems and users accustomed to the default still produce BMP files.

Can I convert BMP to JPG without losing transparency?

BMP files rarely contain transparency (some 32-bit BMP with alpha channel do), but JPEG does not support transparency at all. If your BMP has transparent areas, they will be filled with a white or black background during conversion. For images requiring transparency, convert to PNG instead of JPEG.

Convert BMP to JPG — Compress Windows Bitmap Images for Email, Web, and Social Media

BMP files store raw, uncompressed pixel data — a full-color 1920×1080 BMP is about 6 MB, while an equivalent JPEG is under 1 MB. BMP is not accepted by email services (Gmail blocks large attachments), rejected by social media platforms, and unsupported by most mobile apps. Converting to JPEG reduces file size by 90–98% with visually lossless quality for photographs.

Where BMP Files Come From

BMP (Device-Independent Bitmap, DIB) is the native Windows image format, unchanged since Windows 3.0. Sources include:

Windows Paint: The default save format in Paint on Windows XP and earlier; persists on older systems.
Screenshot tools: Some legacy screenshot applications save to BMP by default.
Industrial systems: Machine vision cameras, lab equipment, and CNC systems often output BMP.
Legacy document scanners: Older flatbed scanners default to BMP output.
Remote Desktop / VNC captures: Some remote session tools save screen captures as BMP.

BMP vs JPEG — Technical Comparison

Compression	None (or RLE for 8-bit)	Lossy DCT
File size (1920×1080)	~6 MB	200–600 KB
Transparency / alpha	Optional (32-bit BMP)	No
Color depth	1, 4, 8, 16, 24, 32-bit	24-bit (8-bit per channel)
Browser support	No	Universal
Email attachment	Often blocked (too large)	Accepted
Social media upload	Rejected by most platforms	Standard format

When to Use PNG Instead of JPG

JPEG is ideal for photographs and complex imagery with gradients. For screenshots, diagrams, logos, and images with sharp text or flat colors, PNG is a better conversion target — JPEG compression introduces visible blocking artifacts around sharp edges, while PNG (being lossless) preserves them perfectly. If your BMP contains text overlays or technical diagrams, use the BMP-to-PNG converter instead.

BMP Transparency and JPEG

32-bit BMP files can contain an alpha (transparency) channel. JPEG does not support transparency. When converting a 32-bit BMP with transparent areas to JPEG, the transparent regions are filled with a solid background color (typically white or black). If you need to preserve transparency, convert to PNG instead of JPEG.
