Azw4 not viewable on Kindle scribe

I have used kindle unpack to create a pdf from the azw4 file. However the resulting pdf is only able to display the first 20 pages of 400. Page 21 onwards gives message error unable to display page on the Scribe. The pdf displays fine for all 400 pages on my Android using moonreader so the pdf is good but the Scribe is failing.

Are there any other options for converting azw4 to format that can be read on Scribe please?

azw4 is just pdf in a wrapper. You can try printing your pdf from some pdf vieweing program to generate another pdf that might work.

As it works on Android, try using one of
1. "Reprint" to PDF from a viewer, as Kovid says, on a PC/Mac
2. Import to a recent version of The GIMP at any desired resolution and export as a PDF. Optionally crop first. Older versions can export in reverse layer order as mpng which can be converted to PDF by ImageMagick
3. Convert/crop from PDF to PDF with k2optpdf or the Calibre plugin that uses it.

4. Convert PDF to PDF with ImageMagick.

There are other options. Ghostscript with Ghostview PDF GUI.
Amazon wants Scribe users to send PDFs to them and convert them to Fixed layout KFX. Then after any annotation it can only get back to PC via Amazon.

Does it work on PC? Ghostview, Foxit, Sumatra, Okular, qpdfview etc.
Is it OK on Pocketbook and Xodo free Android versions? Xodo can create a copy.
Nebo on Android (approx €9.95) can import a PDF and export a copy.

Quote:
The GIMP is a cross-platform image editor available for GNU/Linux, macOS, Windows and more operating systems. It is free software, you can change its source code and distribute your changes.
https://www.gimp.org/
Supports x86-64 and ARM. Someone may have archive of older 32bit versions which would export mpng (each page becomes a frame) rather than PDF direct.

Change default GUI, Toolbox and Icon set to something you recognise if you've not used it. It's daunting at first because it does lots including Photoshop plug-ins and imports. Any save other than native XCF is an export. You need some spare time to learn it.

Unusual Pdf fonts likely to cause scribe to fail ?

If a pdf contains unusual fonts, would that cause kindle scribe to give error unable to display page?
Is there a way to remove unusual fonts from a pdf?
The pdf has tilted text boxes surround by dashes and I think this is reason scribe fails s it's font set is limited

Successfully compressed pdf using xodo and now opens on scribe

Many thanks. Your xodo suggestion has worked. I compressed the file in it from 75mb to 16mb and think this got rid of weird fonts.
