About formats

LRF is the file format associated with Sony's BBeB (Broadband eBook) specification, jointly developed by Sony and Canon and introduced in 2004 with the Sony Librie EBR-1000EP — the world's first commercial E Ink e-reader. The format supports both reflowable text and fixed-layout page rendering, embedding fonts, images, vector graphics, and metadata within a compact binary container. LRF files use a block-based internal structure with object trees describing page layouts, text streams, image resources, and table of contents navigation. Sony's Reader devices and the companion desktop software (Sony Reader Library) served as the primary ecosystem for LRF content throughout the mid-2000s. A key advantage was its early adoption of high-quality font embedding and text rendering optimized specifically for E Ink displays, delivering a reading experience noticeably superior to many competing formats of the era. The format also supported bookmark synchronization, dictionary lookups, and annotations within the Sony Reader ecosystem. However, Sony officially discontinued BBeB/LRF support in 2010, migrating its Reader platform to the industry-standard EPUB format. Today LRF files are primarily encountered in personal ebook collections from that period and can be converted to modern formats using tools like Calibre. The format remains a historically significant milestone as the native format of the device category that launched the modern e-reader revolution.

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 LRF to BMP?

BMP gives you uncompressed bitmap images of ebook pages — useful for printing, editing, or archiving LRF content as images.

Which apps can open BMP files?

Windows Paint, macOS Preview, GIMP, Adobe Photoshop, IrfanView, and essentially every image viewer supports BMP format.

Are BMP files large?

Yes, BMP stores uncompressed pixel data, so files are larger than compressed formats like JPG or PNG. Quality is lossless.

Can I convert BMP to other formats afterward?

Absolutely. BMP is widely supported, so you can easily convert it to PNG, JPG, or any other format using Convertio.

Is LRF to BMP free on Convertio?

Free LRF to BMP conversion is available for standard use. Premium plans give you larger file allowances and faster speeds.
