About formats

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.

DjVu (pronounced "deja vu") is a document format developed at AT&T Labs by Yann LeCun, Leon Bottou, Patrick Haffner, and Paul Howard, first released in 1996. The format was specifically designed for storing scanned documents and images at very high compression ratios while maintaining visual quality suitable for on-screen reading. DjVu achieves this through a layered approach: the document image is separated into a foreground layer (text and line art at full resolution), a background layer (photographs and textures at reduced resolution), and a mask layer that determines which layer is visible at each pixel. This separation, combined with purpose-built compression algorithms for each layer type, typically produces files 5-10 times smaller than equivalent JPEG or PDF scans. One advantage is exceptional compression on scanned pages — a 300 DPI color scan that might occupy 25 MB as TIFF or 500 KB as JPEG typically compresses to 40-80 KB in DjVu while preserving legible text. The progressive rendering model is another strength: DjVu files stream efficiently over networks, displaying a readable low-resolution version almost immediately while progressively refining to full quality. The format supports multi-page documents, embedded text layers for searchability, hyperlinks, annotations, and a shared dictionary mechanism that further compresses collections of similar pages. DjVu is widely used by libraries and archives for digitized historical documents and manuscripts.

Frequently Asked Questions

Why convert BMP to DJVU?

DjVu achieves extreme compression on your BMP — creating compact files ideal for scanned document archiving and online document libraries.

How do I open DJVU files?

DjView, Sumatra PDF, Evince, WinDjView. Most modern operating systems also have built-in support or free viewer options available.

Can I use this on Mac and Linux?

The converter is entirely browser-based — it works on macOS, Linux, Windows, and any other platform with a modern web browser. No OS-specific software needed.

How long does BMP to DJVU conversion take?

Most conversions complete within seconds. Processing time depends on file size and server load, but the entire workflow typically finishes in under a minute.

Are my files safe during conversion?

Convertio uses encrypted connections for all transfers. Your BMP uploads are deleted immediately after conversion, and DJVU downloads are removed within 24 hours.

Is BMP to DJVU conversion free?

Basic conversions are free on Convertio. Premium plans offer faster processing, larger file sizes, and higher daily conversion limits for heavier workloads.
