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.

FB2 (FictionBook) is an XML-based ebook format created by Dmitry Gribov in 2004, designed to provide a clean semantic description of a book's content independent of its visual presentation. Unlike page-layout formats, FB2 encodes structure — title, authors, chapters, annotations, genres, epigraphs, poems, footnotes, and binary attachments (typically cover images) — within a single well-formed XML document. This structural approach means reading applications have full control over rendering, allowing the same file to adapt perfectly to a small phone screen or a large e-ink reader. FB2 became enormously popular in Russia and Eastern Europe, serving as the dominant format on major Russian digital libraries and ebook distribution platforms. One significant advantage is metadata richness: the format's schema mandates detailed bibliographic information including author, translator, series position, publication date, and genre classification, making library management and discovery straightforward. The plain-text XML foundation is another strength — FB2 files are human-readable, easy to validate, and simple to transform using standard XML tools like XSLT. The format specification is freely available on GitHub, and a wide ecosystem of readers, editors, and converters supports it across all major platforms, from desktop applications like Calibre to dedicated e-readers with native FB2 rendering.

Frequently Asked Questions

Why convert BMP to FB2?

FictionBook format incorporates your BMP into a structured ebook — widely used in digital publishing with support for embedded images and metadata.

How do I open FB2 files?

FBReader, Calibre, CoolReader, Moon+ Reader. Most modern operating systems also have built-in support or free viewer options available.

Does BMP to FB2 lose quality?

Lossless formats like PNG preserve every pixel. Lossy formats like JPG trade minimal visual quality for dramatic size reduction — usually imperceptible.

Can I convert BMP to FB2 for free?

Yes — Convertio offers free BMP to FB2 conversion. For professional volumes and larger files, premium plans provide expanded limits and priority processing.

Are my files safe during conversion?

Convertio uses encrypted connections for all transfers. Your BMP uploads are deleted immediately after conversion, and FB2 downloads are removed within 24 hours.

Is batch BMP to FB2 conversion available?

Absolutely — upload multiple BMP files simultaneously and convert them all to FB2 at once. Batch mode saves considerable time on repetitive conversions.
