-**Kindle Comic Converter** is a Python app to convert comic/manga files or folders to EPUB, Panel View MOBI or E-Ink optimized CBZ.
-It was initially developed for Kindle but since version 4.6 it outputs valid EPUB 3.0 so _**despite its name, KCC is
-actually a comic/manga to EPUB converter that every e-reader owner can happily use**_.
-It can also optionally optimize images by applying a number of transformations.
+**Kindle Comic Converter** optimizes black & white comics and manga for E-ink ereaders 
+like Kindle, Kobo, ReMarkable, and more.
+Pages display in fullscreen without margins, 
+with proper fixed layout support.
+Supported input formats include JPG/PNG/GIF image files in folders, archives, or PDFs.
+Supported output formats include MOBI/AZW3, EPUB, KEPUB, CBZ, and PDF.
+
+**NEW**: PDF output is now supported for direct conversion to reMarkable devices! 
+When using a reMarkable profile (Rmk1, Rmk2, RmkPP), the format automatically defaults to PDF 
+for optimal compatibility with your device's native PDF reader.
+
+The absolute highest quality source files are print quality DRM-free PDFs from Kodansha/[Humble Bundle](https://humblebundleinc.sjv.io/xL6Zv1)/Fanatical,
+which can be directly converted by KCC.
+
+Its main feature is various optional image processing steps to look good on eink screens, 
+which have different requirements than normal LCD screens.
+Combining that with downscaling to your specific device's screen resolution
+can result in filesize reductions of hundreds of MB per volume with no visible quality loss on eink.
+This can also improve battery life, page turn speed, and general performance 
+on underpowered ereaders with small storage capacities.
+
+KCC avoids many common formatting issues (some of which occur [even on the Kindle Store](https://github.com/ciromattia/kcc/wiki/Kindle-Store-bad-formatting)), such as:
+1) faded black levels causing unneccessarily low contrast, which is hard to see and can cause eyestrain.
+2) unneccessary margins at the bottom of the screen
+3) Not utilizing the full 1860x2480 resolution of the 10" Kindle Scribe
+4) incorrect page turn direction for manga that's read right to left
+5) unaligned two page spreads in landscape, where pages are shifted over by 1
+
+The GUI looks like this, built in Qt6, with my most commonly used settings:
+
+![image](https://github.com/user-attachments/assets/36ad2131-6677-4559-bd6f-314a90c27218)
+
+Simply drag and drop your files/folders into the KCC window, 
+adjust your settings (hover over each option to see details in a tooltip), 
+and hit convert to create ereader optimized files.
+You can change the default output directory by holding `Shift` while clicking the convert button.
+Then just drag and drop the generated output files onto your device's documents folder via USB.
+If you are on macOS and use a 2022+ Kindle, you may need to use Amazon USB File Manager for Mac.

 ## FAQ
+- Should I use Calibre?
+  - No. Calibre doesn't properly support fixed layout EPUB/MOBI, so modifying KCC output in Calibre will break the formatting.
+    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.
+    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.
+- What output format should I use?
+  - MOBI for Kindles. CBZ for Kindle DX. CBZ for Koreader. KEPUB for Kobo.
+- 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
+- Right to left mode not working?
+  - RTL mode only affects splitting order for CBZ output. Your cbz reader itself sets the page turn direction.
+- Colors inverted?
+  - Disable Kindle dark mode
+- Cannot connect Kindle Scribe or 2024+ Kindle to macOS
+  - Use official MTP [Amazon USB File Transfer app](https://www.amazon.com/gp/help/customer/display.html/ref=hp_Connect_USB_MTP?nodeId=TCUBEdEkbIhK07ysFu)
+    (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)
-- [Combine files/chapters](https://github.com/ciromattia/kcc/issues/612#issuecomment-2117985011)
-- [Flatpak mobi conversion stuck](https://github.com/ciromattia/kcc/wiki/Installation#linux)
+- 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.
