EPUB to BMP Optimization FAQ
Why turn an EPUB ebook into BMP images at all?
+
Images are universally viewable and embeddable — useful for previews, store listings, social posts, or showing a page where an e-reader is not available. Converting an EPUB to BMP freezes the look of the content as pictures.
Will the BMP images keep the book's fonts and styling?
+
The render uses the ebook's default reading typography, so the BMP images show the text styled as a typical reader would display it — headings, emphasis, and embedded illustrations included.
Is the text in the BMP selectable?
+
No — rendering an EPUB page to BMP produces a picture, so the text becomes pixels. For editable or searchable output, convert the EPUB to a document instead of images.
Does BMP support a transparent background?
+
PNG, WebP, and GIF BMP can hold transparency, but ebook pages normally render on a solid page color, so the BMP typically has an opaque background. JPG never stores transparency.
Is my EPUB ebook private during conversion?
+
Yes. Uploaded EPUB files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted BMP are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
How long does EPUB to BMP take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Does DRM affect converting my EPUB to BMP images?
+
Yes — a DRM-protected EPUB is encrypted and cannot be rendered. DRM-free EPUB files convert to BMP normally.
What can I do with the BMP images afterward?
+
Anything you would with any image: embed them on a page, post them, or resize them with /image-resize/. The conversion adds no watermark and claims no rights over the BMP output.
