What is a DJVU file?

DjVu Image

Developed By
AT&T Labs
Initial Release
1996
MIME Type
image/vnd.djvu

DjVu is a raster image file format developed by researchers at AT&T Labs (including Yann LeCun) specifically for storing high-resolution scanned documents. It employs a content-specific compression algorithm that separates images into three layers: background (paper texture), foreground (text/line art), and a bi-level mask (JB2 compression), enabling high compression ratios superior to PDF or TIFF. The format utilizes arithmetic coding (ZM-coder) and wavelet-based compression (IW44) to deliver legible text rendering at low bitrates.

How to open a DJVU file

Most operating systems do not include native kernel support for DjVu rendering. To open these files, users require specialized viewers such as DjView4, WinDjView (Windows), or MacDjView (macOS). Multi-format image viewers like IrfanView (with plugins) and XnView also support the format. For browser-based access, specific plugin implementations or conversion to PDF are often required as modern browsers do not render DjVu natively.

What is a BMP file?

Bitmap Image File

Developed By
Microsoft
Initial Release
1985
MIME Type
image/bmp

The BMP (Bitmap) format, formally known as the Device Independent Bitmap (DIB) file format, is a raster graphics standard developed by Microsoft for the Windows operating system. The file structure consists of a file header (BITMAPFILEHEADER), an information header (typically BITMAPINFOHEADER), a color table, and the pixel array. Data is stored as a grid of pixels with color depths ranging from 1-bit to 32-bit, typically uncompressed, though the format supports lossless Run-Length Encoding (RLE4 or RLE8) and Huffman 1D compression for specific bit depths.

How to open a BMP file

Due to its simplicity and documentation as a core Windows standard, BMP files possess near-universal compatibility. They can be opened natively by virtually all image viewers and web browsers across Windows, macOS, and Linux without additional software. Standard utilities include Microsoft Paint, Apple Preview, and Windows Photos. For advanced manipulation, pixel-based editors like Adobe Photoshop and CorelDRAW are recommended, though the format is rarely used for complex editing due to its large file size.

Developer API

Convert DJVU to BMP via API

Automate DJVU to BMP conversions in three steps: create a job, upload your file, then poll for the result.

Replace YOUR_API_KEY with your RunConvert API key. Get your free API key at runconvert.com/api.

# 1. Create job
curl -X POST https://api.runconvert.com/v3/jobs \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "tag": "djvu-to-bmp",
    "tasks": {
      "upload-file": {
        "operation": "import/upload"
      },
      "convert": {
        "operation": "convert",
        "input": "upload-file",
        "output_format": "bmp"
      },
      "export-result": {
        "operation": "export/url",
        "input": "convert"
      }
    }
  }'

# 2. Upload your file (use upload_url from the response)
curl -X PUT "$UPLOAD_URL" --upload-file input.djvu

# 3. Poll for result
curl https://api.runconvert.com/v3/jobs/$JOB_ID?include=tasks \
  -H "Authorization: Bearer YOUR_API_KEY"
