EPUB a BMP FAQ di cunversione

How do I extract the cover from a EPUB file as BMP?

Upload the EPUB and the converter detects the cover image (usually flagged in the OPF as `cover-image`) and returns it as a BMP. By default we serve the cover at its embedded resolution; the advanced "resize" option lets you target a specific width like 400×600 for a thumbnail grid.

Can I render every page of the EPUB as a BMP?

Yes — switch the advanced option from "cover only" to "all pages" and we rasterize each EPUB page to a BMP at the chosen DPI, then bundle them in a zip. Reflowable EPUB pages render at a fixed page size (A5 / 6×9 / custom) before rasterization.

At what resolution does the extracted BMP come out?

Default is 1600×2400 (high-res cover suitable for retailer upload). Advanced options expose 600×900 (web thumbnail), 1200×1800 (Kindle store cover), 1600×2400 (Apple Books / Kobo), and custom dimensions for ad creatives.

Will the BMP keep the EPUB cover color profile?

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?

Cover-only extraction is instant (under 2 seconds). Full-book rasterization to BMP at 150 DPI takes 30-90 seconds for a 400-page novel; high DPI (300+) doubles or triples that.

Can I use the extracted BMP cover commercially?

Yes if you hold the cover rights (your own book, public domain reissue). Covers of published ebooks usually belong to the publisher; we just extract pixels — we don't change the licensing situation of the underlying EPUB.

What's the file size of a typical extracted BMP cover?

A 1600×2400 cover at JPG quality 90 is 300-800 KB; the same dimensions at PNG are 1-3 MB. The advanced "quality" option trades file size against compression artifacts on the BMP output.
