 ## FAQ
 - Should I use Calibre?
   - No. Calibre doesn't properly support fixed layout EPUB/MOBI, so modifying KCC output (even just metadata!) in Calibre can break the formatting.
+    Additionally, it will break page numbers.
     Viewing KCC output in Calibre will also not work properly.
-    On 7th gen and later Kindles running firmware 5.15.1+, you can get cover thumbnails simply by USB dropping into documents folder.
+    Direct USB dropping is reccomended.
-    On 6th gen and older, you can get cover thumbnails by keeping Kindle plugged in during conversion.
-    If you are careful to not modify the file however, you can still use Calibre, but direct USB dropping is reccomended.
 - Blank pages?
-  - May happen when [using PNG with Kindle Scribe](https://github.com/ciromattia/kcc/issues/665) or [any format with a Kindle Colorsoft](https://github.com/ciromattia/kcc/issues/768). Solve by using JPG with Kindle Scribe or buying a Kobo Colour. Happens more often when turning pages really fast.

Solve by using JPG with Kindle Scribe or buying a Kobo Colour. Happens more often when turning pages really fast. You can try PDF output.
     Going back a few pages and exiting and re-entering book should fix it temporarily.
 - What output format should I use?
-  - MOBI for Kindles. CBZ for Kindle DX. CBZ for Koreader. KEPUB for Kobo. PDF for ReMarkable.

 - All options have additional information in tooltips if you hover over the option.
 - To get the converted book onto your Kindle/Kobo, just drag and drop the mobi/kepub into the documents folder on your Kindle/Kobo via USB

     (no login required). Works much better than previously recommended Android File Transfer. Cannot run simutaneously with other transfer apps.
 - How to make AZW3 instead of MOBI?
   - The `.mobi` file generated by KCC is a dual filetype, it's both MOBI and AZW3. The file extension is `.mobi` for compatibility reasons.
-- [Windows 7 support](https://github.com/ciromattia/kcc/issues/678)
-- Image too dark?
-  - The default gamma correction of 1.8 makes the image darker, and is useful for faded/gray artwork/text. Disable by setting gamma = 1.0
 - Huge margins / slow page turns?
   - You likely modified the file during transfer using a 3rd party app. Try simply dragging and dropping the final mobi/kepub file into the Kindle documents folder via USB.
