EPUB to JPG Conversion FAQ
How do I extract the cover from an EPUB file as JPG?
+
Upload the EPUB and the converter detects the cover image (usually flagged in the OPF as `cover-image`) and returns it as a JPG. 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. JPG is the JPEG standard from 1992, served under the .jpg, .jpeg and .jfif extensions alike, and after three decades it is still the format most cameras and most websites use for photographs.
Will the JPG open directly in a browser?
+
Yes, and the EPUB would not have. Browsers ship a decoder for JPG and none for EPUB, so an EPUB link forces a download while a JPG renders inline. That is usually the deciding factor when the file is going onto a web page rather than into an application. JPG compresses natural photographs superbly and is readable by literally every device, browser and printer in existence.
How are the pages of a reflowable book turned into fixed images?
+
By rendering them at a chosen page size first, because a reflowable book has no inherent pages — the reader creates them from screen width and font size. The converter picks a standard page geometry, lays the text out onto it, and renders each resulting page as one image. Change the page size and you get a different number of images from the same book.
What quality setting should I use for the JPG output?
+
Quality 85 is the sensible default and the one used unless you change it — visually indistinguishable from the source at normal viewing distance, at roughly a fifth of the size of a lossless equivalent. Push to 95 for anything that will be edited or printed, and drop to 70 for thumbnails where size dominates. JPG is lossy: the image is transformed with a DCT, quantised, and entropy-coded, with a quality knob controlling how much is discarded.
Why does my EPUB file refuse to convert?
+
DRM, in almost every case. A protected EPUB is encrypted and tied to an account, and no converter can decrypt it — ours included. Files you created yourself, or bought from a DRM-free store, convert without any trouble at all. EPUB has no fixed pagination, so page numbers are meaningless, and complex layout — tables, equations, multi-column — degrades badly.
Can I convert only part of the EPUB instead of all of it?
+
Yes — the page-range option takes `1-5`, `1,3,5` or `all`, so a single chapter, an appendix or just the cover can be extracted without processing the rest. On a long document that is the difference between a handful of files and several hundred.
Do I get one image per page?
+
Yes — each page renders as its own JPG file and the set arrives as a ZIP. The page-range option narrows that down when you only want a cover or a single chapter, and setting it to a single page returns one file rather than an archive.
Can I render every page of the EPUB as a JPG?
+
Yes — switch the advanced option from "cover only" to "all pages" and we rasterize each EPUB page to a JPG 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 JPG 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 JPG keep the EPUB cover color profile?
+
Yes — ICC profile embedded in the EPUB cover (if any) is preserved into the JPG. Most retailer-uploaded ebook covers ship as sRGB, which the JPG keeps. For print-ready CMYK output, use a separate /image-to-cmyk/ step after extraction.
Can I extract specific pages of the EPUB as JPG, 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 JPG files. Useful for grabbing illustrations or pull-quotes for marketing.
Why is my extracted JPG 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.
