Yes — ICC profile embedded in the EPUB cover (if any) is preserved into the BMP. Most retailer-uploaded ebook covers ship as sRGB, which the BMP keeps. For print-ready CMYK output, use a separate /image-to-cmyk/ step after extraction.
Can I extract specific pages of the EPUB as BMP, not just the cover?
+
Yes — the page-range advanced option accepts inputs like `1,3,5` or `10-15` to pick which rendered EPUB pages get turned into BMP files. Useful for grabbing illustrations or pull-quotes for marketing.
Why is my extracted BMP cover blurry or low-res?
+
The EPUB contained a low-resolution cover. Many older ebooks ship with 600×900 or smaller cover JPGs — upscaling makes them softer, not sharper. For marketing assets, source the high-res cover from the publisher rather than upscaling the in-book copy.
What about transparency in the BMP?
+
PNG BMP preserves transparency if the EPUB cover had an alpha channel (rare for ebooks; common for promo art). JPG BMP cannot store transparency and flattens onto white. For logo / icon work, target PNG or WebP BMP.
Does the EPUB to BMP converter strip text from page images?
+
No — rasterization is pixel-faithful. Text on the EPUB page renders as pixels in the BMP, no OCR or text extraction happens. For editable text, use /epub-to-docx/ or /epub-to-txt/ instead of this image route.
Is my EPUB file private during BMP extraction?
+
Yes — uploaded EPUB files are processed in isolated workers and deleted within minutes. Cover extraction is a single-pass read with no human review.
How long does it take to render a 400-page EPUB as BMP files?
