Free online TIFF to FB2 converter

1. Source format: TIFF

TIFF (Tagged Image File Format) is a high-quality raster image format widely used in publishing, scanning, archiving, and professional photography. It is popular with scanners, graphic designers, print workflows, and document archives because it can store images with minimal loss, support multiple pages, and preserve fine detail. TIFF files are often used for books, magazines, receipts, manuscripts, and scanned documents when image fidelity matters more than file size.

2. Target format: FB2

FB2 (FictionBook 2.0) is an XML-based e-book format designed mainly for novels, articles, and other text-centric books. It is especially common in Russian-language e-book collections and reading apps. FB2 files are valued for their structured text, metadata support, and good compatibility with e-readers and library software. Unlike image formats, FB2 is intended for reflowable text rather than fixed-page graphics.

3. How to perform the conversion

Converting TIFF to FB2 is not a direct image-to-ebook transformation in the usual sense. A TIFF file is an image, while FB2 is a structured book format. In practice, the conversion only makes sense if the TIFF contains scanned pages of text. The best workflow is:

1. Extract text from the TIFF using OCR software. Good desktop options include ABBYY FineReader, Tesseract, or Adobe Acrobat if the TIFF is part of a scanned document set.
2. Clean and structure the recognized text into chapters, headings, and paragraphs. FB2 works best when the content is properly organized.
3. Save or export to FB2 using an e-book editor or converter that supports FB2 output. A practical desktop tool is Calibre, which can convert text-based documents into FB2 after OCR has produced editable text.

If you already have the text in a document format such as DOCX, HTML, or TXT after OCR, you can convert it to FB2 in Calibre by opening the file and choosing Convert books, then selecting FB2 as the output format. If your TIFF is a single scanned page or image-only file, first run OCR; otherwise, the result would be an FB2 file containing only embedded images, which is usually not useful for e-reading.

You can also convert the file on 101convert.com for free, without installing any software, if the site supports this conversion path.

4. Notes on quality, compatibility, or limitations

TIFF to FB2 is inherently limited because the source is an image format and the target is a text-oriented e-book format. The quality of the final FB2 depends almost entirely on the OCR accuracy and the cleanliness of the scan. Poor contrast, skewed pages, handwriting, decorative fonts, or low-resolution scans can produce recognition errors that must be corrected manually.

FB2 does not preserve the original page layout of a TIFF scan in the same way a PDF or image archive would. Instead, it is designed for reflowable reading, so tables, columns, footnotes, and complex layouts may need manual reconstruction. If your goal is to preserve the exact appearance of the scanned pages, FB2 is usually not the best target format. If your goal is to make the text readable on e-readers, OCR plus FB2 can work well.
