kepubverto � EPUB to KEPUB for Kobo, without breaking the book

Kayadelenium — Fri, 09 Oct 2026 19:40:23 GMT

Some of you know epubveri, epubsana and epublift from their threads here. This is the fourth member of the family.

While I was building those three, I converted a lot of books to KEPUB, with kepubify and with epublift's own Kobo conversion, and I checked every result with epubveri. Again and again, a book that was valid before the conversion had errors after it. kepubify is a good program, and it is the reason most of us know what a KEPUB is; I learned the format from it. But I wanted a converter I could trust with any book, so I wrote kepubverto. It is built around one rule: it never makes a book worse.

What it does

It gives a book what a Kobo needs for reading statistics, faster page turns and the proper progress bar, and nothing else. Your text and the rest of the book are left as they were. The span ids are the same as kepubify's, so if you switch, your reading position and highlights should carry over.

kepubverto converts; it does not check or repair. That is the job of epubveri and epubsana, and the planned Sigil and calibre plugins will run them together. kepubverto is built so that a valid book stays valid, and I test that on my whole shelf before every release. On my Kobo, reading position and the progress bar work, both on a converted book alone and at the end of my epublift chain (validate, metadata, optimize, convert).

Why it is safe to point at a real book

It never writes over your file. book.epub becomes book.kepub.epub next to it.
An existing output file is replaced only if you ask for it (-f).
A chapter it cannot convert safely is left exactly as it was, and it tells you which one.
The web page converts inside your browser. The book is not uploaded anywhere.

How to use it today

Until the plugins exist:

In your browser, nothing to install: https://veripublica.github.io/kepubverto/ Drop an EPUB on the page and download the KEPUB.
Command line: binaries for Windows, macOS and Linux on the releases page. The macOS and Windows binaries are not code-signed, so the first run shows the usual warning. Or, with Rust installed: cargo install --locked kepubverto

Code:

kepubverto -i book.epub

What it does not do (yet)

kepubify's optional extras (smarten punctuation, hyphenation, extra CSS and the rest) are not in this first version, and I have not decided yet which of them will come. It does not add a dummy title page, and it does not change the book's metadata or cover.

What would help

1. Your device. I have tested on my own Kobo. If yours is a different model or firmware, convert a book and tell me whether position, progress and page turns behave. If you switch a book you already read with kepubify, I would especially like to know whether your highlights and last position come through.

2. A book that came out worse. Anything that opens, looks or behaves differently after conversion. Your original is untouched, so you can compare the two, and epubveri or epubcheck will check the result.

3. Which kepubify option you miss most. That decides which one comes first.

PocketBook Q and Verta

apastuszak — Fri, 09 Oct 2026 19:32:41 GMT

Looks like we're getting 3 new ereaders before the end of the calendar year. We're getting a Verta, Verta Color, and the Q. All 3 of these are getting a MUCH faster CPU, the Rockchip RK3566, a quad-core ARM Cortex-A55 chip running at 1.8 GHz. That's significantly faster than the 1 GHZ dual core CPU that they currently use.

What I don't get is why the Era Lite, which just came out this year, got the same old CPU as models from a few years ago and not this new chip.

I really like the form-factor of the Era Lite. I just wish the UI was a little faster.

Problems Converting HTML to EPUB

ezechias — Fri, 09 Oct 2026 19:13:46 GMT

Hi, for years I have been converting HTML files to produce both AZW3 and EPUB files for two different readers (Kindle Paperwhite & FBReader on Pixel phone) Recently, however, converting the HTML to EPUB produces an empty document. The same file produces AZW3 just fine, so when I convert the AZW3 file to EPUB, it also comes out fine, but the end section is missing. I have attached 4 files. The original HTML file, the empty EPUB, the good AZW3 and the EPUB converted FROM the AZW3 which has the missing end section. I am using portable Calibre 9.16.0 on and an up-to-date Windows 11 machine. The only settings I am changing are device format to Paperwhite 3, linearize tables, no table of contents, and this extra CSS: body {text-align: left;}
p {text-align: left;}
Thanks for your help.

[Plugin] Readest: sync progress, highlights and stats between KOReader and Readest

chrox — Fri, 09 Oct 2026 17:10:21 GMT

Hi everyone,

chrox here. I spent years working on KOReader, and these days I work on Readest, an open-source reader for desktop, mobile and web (see my Readest thread in Reading and Management). I still read on e-ink with KOReader, so I wrote a plugin that keeps KOReader and Readest in sync. You can read on your Kobo or Kindle at night and continue on your phone the next day.

What it does

Syncs reading progress automatically (on page turns and when you close the book), or on demand
Syncs highlights, notes and bookmarks both ways
Syncs KOReader reading statistics
Readest library view: browse your Readest library in KOReader and download books from the cloud with a tap
Upload the current book to your Readest library
Nearby BookDrop: receive books over Wi-Fi from Readest on your phone or computer
Built-in update check

Books are matched by KOReader's partial MD5, so the same file on both sides is recognized as the same book.

Install

Download Readest--1.koplugin.zip from https://github.com/readest/readest/releases/latest
Unzip it into KOReader's plugins folder, so you end up with koreader/plugins/readest.koplugin
Restart KOReader, then open Tools → Readest and sign in with your Readest account (email and password; if you signed up with Google or Apple, set a password in the Readest app first under Account)
Try a manual push and pull, then turn on Auto sync

KOReader 2026.07 or newer is recommended.

If you only need progress sync, Readest can also connect to a KOReader sync server (kosync) directly, with no plugin needed. Setup guide: https://github.com/readest/readest/w...reader-devices

Feedback and bug reports are welcome here or on GitHub (https://github.com/readest/readest/issues).

Mystery and Crime Kabel, Walther: Harald Harst (337) - Die Havelpiraten. V1.0 [German] 09.10.2026

Zentaurus — Fri, 09 Oct 2026 16:45:38 GMT

Die Havelpiraten

Als die elektrische Beleuchtung wieder aufflammte und der gro�e Musiksalon des Herrn von Rapper in einer F�lle von Licht schwamm, klirrten die Saiten des ge�ffneten Bechsteinfl�gels noch immer leise nach.

Der scharfe, kurze, harte Knall des Schusses, durch den G�nther von Rail niedergestreckt worden war, hatte sogar die Saiten des Fl�gels zum Klingen gebracht.

F�nf Menschen sa�en oder standen mit farblosen Gesichtern wie versteinert da und konnten die weiten Augen nicht losrei�en von der auf dem hellen Perserteppich niedergesunken reglosen Gestalt.

Die �berlebenden dieser unfa�baren Trag�die erwachten erst allm�hlich aus ihrer starren Versunkenheit. Jeder von ihnen hatte in diesen Sekunden, die dem j�hen Versagen der Beleuchtung, dem harten Knall, dem Sturz des K�rpers und dem Wiederaufflammen des Lichtes gefolgt waren, denselben mi�trauisch sp�renden Gedanken nachgehangen:

Wer war’s?!

Text und Cover stammen von der Walther-Kabel-Seite, vielen Dank!

PRS-T1 Looking for Sony PRS-T1 kernel source: linux-2.6.35.3-111114.tgz

ikekaras — Fri, 09 Oct 2026 13:45:54 GMT

Hi everyone,

I�m still tinkering with a Sony PRS-T1 and trying to find the kernel source archive linux-2.6.35.3-111114.tgz that Sony published for firmware 1.0.04.12210.

It�s linked in this old compilation guide, but Sony�s download now returns 404. Does anyone still have the archive, an extracted copy, or a working mirror?

I�ve also requested it from Sony, but thought someone here might have kept it.

Thanks!

Hello!

Lost Folio � The Index of Unwritten Things | A standalone psychological mystery

LostFolio — Fri, 09 Oct 2026 11:29:01 GMT

Posting on behalf of Lost Folio to introduce our novel, The Index of Unwritten Things.

Elias Vale restores damaged paper. Then a plant on an office windowsill changes, and every photograph and reference book insists it has always been that way. A staff photograph dated 1964 brings a more personal problem: it contains a man with his face, accompanied by records of a life he never lived.

This is a standalone psychological mystery about memory, identity and who gets to decide which version of a life becomes official. It may appeal to readers who enjoy unsettling archives, contradictory evidence and reality that becomes less certain the more closely it is examined. No earlier Lost Folio book is required.

Available in Kindle, paperback and hardcover.
Amazon Kindle listing: https://www.amazon.com/dp/B0HL3WC1K5

Creation disclosure: the novel uses AI-generated prose under human editorial direction. This introduction was prepared with an AI assistant for Lost Folio.

If you have questions about its premise, format or connection to the illustrated Lost Folio books, we can answer without spoilers.

Help creating dictionary from scratch with Pglossary.

galax — Fri, 09 Oct 2026 11:03:30 GMT

I am trying to create a dictionary in stardict format from clean slate with pyglossary.

The easy part is converting a .tab file to .ifo, this creates the three files of stardic
t dictionary:

Code:

mydictionary.dict

mydictionary.idx

mydictionary.ifo

Some question regarding these steps, is a pyglossary created dictionary comformant with
koreader stardict engine?

Are there any steps required to sort dictonary entries as I add them?

I am aware that stardict needs some sort of strict order.

Pyglossary has also three more stardict formats:

StardictMergeSyns
StardictTextual

But no mention on how to use these.

And lastlyo, is it possible to use images in koreader dictionary pop up? Stardict got an
option to add audio and images resources.

I'd like to include images into the dictionary entries.

Thanks in advanced.

10 free ebook copies for honest reviews � dystopian literary thriller (68pp)

AuzelMakadam — Fri, 09 Oct 2026 08:23:28 GMT

Offering 10 free ebook copies of "My Brother on the Moon: Volume One � A Dystopian Thriller" (~68 pages, on Kindle Unlimited) in exchange for honest reviews on Goodreads and/or Amazon.

In a city that gives every citizen 23 hours plus 1 hour of borrowed time, a parasite carries a brother's consciousness � and the extra hour is paid for by someone else.

- Length: ~68 pages / ~20k words (a quick read)
- Genre: literary dystopian thriller
- Published Nov 9, 2025 � finished book
- Review window: 3-4 weeks
- To get a copy: reply here or email dexswellenstein@outlook.de � I'll send a PDF/EPUB.

First come, first served. Thanks!

Small correction to my pitch above (better describes the book):

In Ventenstein City, a virus gives the infected one murderous hour a day. Auzel Makadam buried a hundred strangers before a man named Dexs taught him the difference between surviving and living � then betrayed him and died. Now Auzel hunts through a city where anyone might be infected, and trust itself is a death sentence.

Quick update for anyone watching this thread: Book One is free on Kindle this weekend, Oct 10-11. If the premise sounded interesting but $2.99 felt like a gamble on an unknown name, this is the zero-risk window. Happy to hear what you think, here or on Goodreads.

EPUB Translator: AI book translation with bilingual EPUB output

EPUBTranslator — Fri, 09 Oct 2026 08:05:41 GMT

Hi everyone,

I'm the developer of EPUB Translator, a web-based tool for translating EPUB books. I'm sharing it here for readers who want to read a book in another language or compare the translation with the original.

The main features are:
- Translation across more than 40 languages
- Whole-book context and a glossary to help keep names and terminology consistent
- Preservation of EPUB structure, images, and supported formatting
- Downloads as a translated EPUB or a bilingual EPUB

Full-book translation is paid. A free preview lets you inspect a sample before paying.

This is AI translation, so it can miss nuance or make mistakes. The preview is a useful way to check how it handles your book; the output shouldn't be treated as a professionally reviewed translation. Please only upload material you have the rights or permission to translate.

You can try it here: https://epubtranslator.com

Feedback on the translation, formatting, or bilingual reading experience is welcome.
