BMP to JPG Converter

How to convert BMP to JPG

Drop your BMP file above or click to browse. The tool converts it to JPG instantly using your browser's Canvas API. Nothing is uploaded. BMP files are uncompressed, so even a modest-sized image can be several megabytes — the JPG output is typically 90–95% smaller.

Why are BMP files so large?

BMP (Bitmap) is a raw, uncompressed image format from the early days of Windows. It stores every pixel without any compression, making files extremely large — a 1920×1080 BMP is about 6 MB. Converting to JPG at 90% quality reduces this to roughly 300–600 KB with no visible difference.

Frequently asked questions

How much smaller will my JPG be compared to BMP?

Typically 90–95% smaller. A 5 MB BMP usually converts to a 200–500 KB JPG at 92% quality with no visible quality difference for photographs. For graphics with solid colors, the reduction may be smaller.

Will my image lose quality when converting BMP to JPG?

BMP is lossless (uncompressed); JPG is lossy. The converter uses 92% quality which is visually indistinguishable from the original for photos. If you need lossless output, use the PNG Maker to convert BMP to PNG — PNG is lossless and still much smaller than BMP.

Does my BMP file get uploaded anywhere?

No — conversion runs entirely in your browser. Your file never leaves your device.

Can I convert multiple BMP files at once?

Yes — select or drop multiple BMP files and all will be converted simultaneously.

Why do I still have BMP files?

BMP files are commonly produced by Windows screenshot tools (older versions of Paint), certain scanners, and legacy software. Some Windows programs still save in BMP by default. Converting to JPG is almost always the right move for storage and sharing.

Should I convert BMP to JPG or PNG?

For photographs, convert to JPG — much smaller files, minimal quality loss. For graphics with sharp edges, text, or flat colors, convert to PNG using the PNG Maker — PNG is lossless and handles those images better than JPG.

Do you also convert TIFF files?

Yes — use the TIFF to JPG converter for TIFF and TIF files. Both TIFF and BMP are uncompressed formats commonly found in professional and legacy workflows.

Need to convert a different format?

The Image to JPG converter accepts any image format — AVIF, HEIC, WebP, PNG, TIFF, GIF, and more — in one place.

What is a BMP file?

BMP (Bitmap Image File) is an uncompressed raster image format developed by Microsoft in the 1980s for the Windows operating system. It stores raw pixel data with no compression, which means every pixel's color values are written directly to disk. This makes BMP files very fast to read and write by programs, but the file sizes are enormous compared to modern formats.

Why are BMP files so large?

BMP files apply no compression — they store every pixel's color data individually. A 1920×1080 BMP at 24-bit color is roughly 5.9 MB, while an equivalent JPG would be around 300–600 KB. That is a 90–95% size difference with no visible quality change for photographic content. Even simple graphics that would be tiny as PNG can be several megabytes as BMP.

BMP vs PNG vs JPG — which should I use?

BMP is a legacy format best avoided for modern use — it has no compression advantages and is not supported on the web. PNG is ideal for graphics, logos, screenshots, and any content with sharp edges or flat colors, since it is lossless and compresses well. JPG is best for photographs and complex images where lossy compression is acceptable. For almost any use case, either PNG or JPG is a better choice than BMP.

How do I convert BMP to JPG in Windows?

In Windows, open the BMP file in Microsoft Paint, go to File → Save As, and select JPEG from the file type dropdown. You can also use this free online tool — just drag your BMP file above and click download. The online method works on any device without installing anything, and processes the file entirely in your browser.
