About formats

DOC is the binary document format of Microsoft Word, the word processor first released in October 1983 for MS-DOS and later becoming the dominant document creation tool worldwide. The format stores documents as OLE2 compound document files — a binary container with multiple internal streams holding text content, formatting information, embedded objects, macros, and metadata. The text stream uses a complex system of formatting runs, section descriptors, paragraph and character property tables, and style definitions to represent arbitrarily complex document layouts including columns, headers, footnotes, tables, floating images, tracked changes, and mail merge fields. The format evolved substantially through Word versions, with Word 97 establishing the binary structure that remained standard through Word 2003 and created the .doc files most commonly encountered today. One advantage is near-universal compatibility — DOC files can be opened by virtually every word processor and document viewer across all platforms, from Microsoft Office to LibreOffice, Google Docs, and Apple Pages. The format's rich feature support is another strength: DOC handles complex layouts, embedded OLE objects, VBA macros, and revision tracking that power enterprise document workflows. Although Microsoft introduced the XML-based DOCX format with Office 2007, DOC remains heavily present in existing document archives and continues to be produced by organizations maintaining compatibility with older Word installations.

BMP (Bitmap) is a raster image file format developed by Microsoft for the Windows operating system, introduced with Windows 3.0 in 1990. The format stores pixel data in a straightforward structure: a file header specifying dimensions, color depth, and compression method, followed by an optional color palette and then the raw pixel array. BMP supports color depths from 1-bit monochrome through 4-bit and 8-bit indexed color to 16-bit, 24-bit true color, and 32-bit with alpha channel. Most BMP files store pixels uncompressed (BI_RGB), though optional RLE compression is available for 4-bit and 8-bit modes. Pixels are arranged in bottom-up row order by default, with each row padded to a 4-byte boundary. One advantage is absolute simplicity — the format has no complex encoding, filtering, or compression layers, making BMP files trivial to read and write programmatically in any language. This simplicity also means BMP images render with zero decoding overhead, useful in scenarios where decompression latency matters. The format's deep Windows integration is another strength: BMP is the native bitmap format for Windows GDI, clipboard operations, and device-independent bitmap (DIB) handling, ensuring first-class support across the entire Windows ecosystem. While BMP's lack of compression produces large files unsuitable for web use or storage-constrained environments, it remains widely used as an intermediate format in image processing, as a clipboard exchange format, and in embedded systems where decoding simplicity outweighs file size.

Frequently Asked Questions

Why convert DOC to BMP?

BMP provides uncompressed, raw image data — converting DOC to BMP is useful when you need maximum fidelity without compression artifacts.

What opens BMP files?

BMP files open natively on Windows (Paint, Photos), macOS (Preview), and in cross-platform editors like GIMP, Photoshop, and IrfanView.

Are BMP files larger than JPG?

Yes, BMP files are uncompressed and significantly larger. This tradeoff gives you artifact-free images of your DOC pages.

Is DOC to BMP conversion free?

Convertio offers free DOC to BMP conversion. Paid plans unlock extended capacity for frequent or bulk conversions.

Does the conversion handle tables and charts?

All visual elements in your DOC — tables, charts, images, and text — are rendered accurately in the BMP output images.
