EPUB کرنے کے لئے PNG تبادلوں کے اکثر پوچھے گئے سوالات
How do I extract the cover from a EPUB file as PNG?
+
Upload the EPUB and the converter detects the cover image (usually flagged in the OPF as `cover-image`) and returns it as a PNG. 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 PNG?
+
Yes — switch the advanced option from "cover only" to "all pages" and we rasterize each EPUB page to a PNG 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 PNG 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 PNG keep the EPUB cover color profile?
+
Yes — ICC profile embedded in the EPUB cover (if any) is preserved into the PNG. Most retailer-uploaded ebook covers ship as sRGB, which the PNG keeps. For print-ready CMYK output, use a separate /image-to-cmyk/ step after extraction.
Can I extract specific pages of the EPUB as PNG, 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 PNG files. Useful for grabbing illustrations or pull-quotes for marketing.
Why is my extracted PNG 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 PNG?
+
PNG PNG preserves transparency if the EPUB cover had an alpha channel (rare for ebooks; common for promo art). JPG PNG cannot store transparency and flattens onto white. For logo / icon work, target PNG or WebP PNG.
Does the EPUB to PNG converter strip text from page images?
+
No — rasterization is pixel-faithful. Text on the EPUB page renders as pixels in the PNG, 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 PNG 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 PNG files?
+
Cover-only extraction is instant (under 2 seconds). Full-book rasterization to PNG at 150 DPI takes 30-90 seconds for a 400-page novel; high DPI (300+) doubles or triples that.
Can I use the extracted PNG 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 PNG 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 PNG output.
