Free online BMP to FB2 converter

Source format: BMP

BMP (Bitmap) is a classic raster image format developed for Windows. It stores pixel data with little or no compression, which makes it simple and widely supported but often very large compared with modern image formats. BMP files are commonly used for screenshots, icons, scanned images, and graphics that need to preserve exact pixel detail.

Target format: FB2

FB2 (FictionBook 2.0) is an XML-based e-book format designed mainly for novels, stories, and other text-centric books. It is popular in some e-book libraries and reading apps because it keeps a clean document structure, supports metadata, and works well for reflowable reading on different screen sizes. FB2 is best suited to books with text and simple illustrations rather than image-only content.

How to perform the conversion

Converting BMP to FB2 is unusual because the formats serve very different purposes: BMP is an image format, while FB2 is an e-book container for structured text. In practice, the conversion usually means embedding a BMP image inside an FB2 book, often as a cover image or illustration, rather than turning the image into readable book text.

1. Prepare the BMP file. If the image is meant to be a cover or illustration, make sure it is cropped and sized appropriately before conversion.
2. Open the built-in converter on 101convert.com and choose the BMP to FB2 conversion option. You can convert the file online for free without installing any software.
3. Upload the .bmp file.
4. If the converter offers options for image placement or book metadata, set them as needed. For example, choose whether the image should be used as a cover or inserted into the FB2 content.
5. Start the conversion and download the resulting .fb2 file.
6. Open the FB2 file in a compatible reader to verify that the image appears correctly and that the file structure is valid.

If you need to build a proper FB2 book around the image, desktop tools such as Calibre, FB2 editors, or XML editors can help you add metadata, title information, and text content before saving as .fb2.

Notes on quality, compatibility, and limitations

Image-only conversion has limited value because FB2 is not intended as a general image format. A BMP file converted to FB2 will usually remain a single embedded image unless additional text is added manually.

File size may increase if the BMP is embedded without compression, since BMP files are often large and FB2 does not inherently compress image data the way some other e-book workflows do.

Reader compatibility varies. Most FB2 readers handle embedded images well, but some may display them differently depending on metadata, XML structure, and image dimensions.

Best results come from using BMP as source artwork for a cover or illustration, not as the main content of the book. If your goal is to create a readable e-book from scanned pages, OCR and a text-based workflow are usually better than direct image-to-FB2 conversion.
