Which conversions are supported?

Any direction between PDF, EPUB, and FB2 — PDF to EPUB, PDF to FB2, EPUB to PDF, EPUB to FB2, FB2 to PDF, and FB2 to EPUB.

Is my file uploaded anywhere?

No. The file you choose is parsed locally in your browser with JavaScript, and the converted file is generated locally too — nothing is sent to a server.

Will the converted file keep the original layout, images, and fonts?

No. This tool extracts plain paragraph text from the source file and rebuilds it as a clean, reflowable document in the target format. Images, tables, columns, and custom fonts from the source are not carried over.

How is text extracted from each format?

From a PDF, by reading each page's text layer and reconstructing paragraphs from line positions. From FB2, by reading its paragraph elements. From EPUB, by reading the spine chapters in order and pulling text out of their paragraph and heading elements.

What if my PDF is scanned images with no text layer?

It won't work well — this tool reads the text layer already embedded in the PDF and doesn't run OCR, so a scanned PDF with no selectable text will produce an empty or near-empty result.

Is there a file size limit?

No hard limit is enforced, but very large books are parsed and rendered entirely in your browser tab, so extremely large files may be slower depending on your device.
