BMP: The Uncompressed Bitmap Format

BMP (Bitmap) is an uncompressed raster image format developed by Microsoft for Windows operating systems. BMP files store every pixel's color value without any compression, resulting in large file sizes but perfect image fidelity. A single A4 scan at 300 DPI in 24-bit color produces a 25 MB BMP file.

Because BMP files are uncompressed, they provide the highest possible OCR accuracy — no compression artifacts degrade character edges. Convert JPG to Word achieves 99%+ text recognition accuracy on BMP files with clear printed text at 300 DPI.

When to Use BMP for Document Conversion

  • Maximum OCR Accuracy: BMP provides pixel-perfect input for OCR engines. Use when accuracy is critical (legal, medical documents).
  • Direct Screen Captures: Windows Print Screen captures save as BMP in the clipboard. Pasting into Paint and saving as BMP preserves full quality.
  • Avoid for Storage: BMP files are 4-12× larger than compressed alternatives. Convert to PNG for lossless archival or JPG for space-efficient storage.

BMP to — Common Questions

BMP files are large because they store every pixel without compression. A 2480×3508 pixel image at 24-bit color requires 26.1 MB as BMP. The same image compressed as JPG at 85% quality is approximately 2 MB. BMP trades file size for perfect pixel fidelity.

Yes, BMP produces slightly better OCR accuracy (99%+) than JPG (95-98%) because BMP has zero compression artifacts. However, the difference is small for well-compressed JPG files (85%+ quality). The 1-4% accuracy gain rarely justifies the 10× larger file size.

Yes, any BMP file saved from Windows Paint, MS Paint, or similar applications is fully supported. Paint saves BMP files in the standard Windows DIB format that Convert JPG to Word processes directly.

No, upload BMP files directly. Converting BMP to PNG before upload is unnecessary — the OCR engine processes both formats with equal accuracy. However, if upload speeds are slow due to large BMP file sizes, pre-converting to PNG reduces file size by 3-4× without quality loss.
