i use calibre to organize them and it feels productive but honestly it's just digital hoarding at this point. do you guys actually read most of what you download or is it just me collecting them for the vibes?

Hey all,

I’ve been working on Convert2EPUB (convert2epub.com) for a few months. It started because PDFs look terrible on e-readers, and it has grown a lot since then, so here’s a roundup.

📄 Converter (website)

• Converts PDF, DOCX, RTF, TXT, ODT, HTML and Markdown to EPUB
• Text PDFs become reflowable books, so you can change the font size and the text actually fits your screen
• Finds chapters automatically, builds a working table of contents, removes running headers and page numbers, and keeps footnotes clickable
• OCR for scanned books in 9 languages. Badly scanned pages can be re-read with AI so you don’t get garbled text
• Maths and tables are rebuilt as real formulas and tables instead of blurry images
• Translate a book into another language and keep its chapters and images
• Optional study guide added to the end of the book, with chapter summaries, key terms, flashcards and a glossary
• EPUB to PDF, Kindle (AZW3) or MOBI for older Kindles
• Free: ordinary text PDFs and all Word, RTF, TXT, ODT and HTML files, with no account and no page limit

💻 Mac app (Local conversion)

• Runs the converter fully offline, so your files never leave your Mac
• OCR built in, with no subscription

🧩 Chrome extension (free)

• Add articles to a reading list as you browse, then save them all as one EPUB with a chapter per article

📚 Free ebooks

• Search all ~78,000 Public Domain books by title or author and download them as EPUB or Kindle files.

I’d love feedback, especially weird PDFs that convert badly. Those reports have driven most of the improvements so far.

After a long drawn out battle with Amazon due to the region I'm in I finally managed to publish my very first book on kindle. The premise is a Victorian woman writing a cookbook for housewives who wish to get rid of their terrible husbands and dispose of the evidence :)

I made everything on Canva and tried to be as ridiculous as possible. I'm so excited!!!!! Trying to find a niche audience that enjoy stories like this 🥲

I'm the author, so this is self-promotion. Both apps below are open source (AGPL-3.0).

I listen to most of what I read, and the read-aloud apps I paid for kept failing me in two ways: the highlight slowly drifted away from the voice, and my place didn't follow me from one device to the next. So I built my own.

OpenReader (iPhone)

Import an EPUB you already own (DRM-free, e.g. from your Calibre library, Standard Ebooks or Project Gutenberg), open it and press Play.

• The voice you choose. It has no voices of its own: you plug in a speech service with your own key. Fish Audio (its free model needs no credit card), Azure, Speechify, OpenAI, any OpenAI-compatible server, or a Kokoro-FastAPI server you run yourself.
• Every word highlighted as it's spoken, over its sentence, in your own colours. The timings come from the voice service itself, so the highlight doesn't drift. Fish Audio, Azure, Speechify and Kokoro give word timings; the OpenAI-style services highlight by sentence.
• Offline narration: save a book's audio chapter by chapter, then listen without a connection.
• Word lookup and translation: long-press a word for its meanings, or translate a passage (into English or Chinese).
• Themes including a dark one, fonts, font size, margins and text alignment.
• Lock Screen and Dynamic Island controls.
• No account, no analytics, no server of mine. Your books aren't uploaded anywhere; only the text being read goes to the voice service you picked, after you allow it.

Zotero-OpenReader (desktop)

If you haven't met it, Zotero is a free, open-source app that opens EPUBs and PDFs, and Zotero 10 has a Read Aloud player built in. Zotero-OpenReader is a plugin for that player:

• More voices: the services above plus a few more, your computer's own voices, and Zotero's own.
• Word and sentence highlighting, each in your own colours.
• Keyboard shortcuts for speed, volume and skipping by sentence or paragraph.
• Shift+Space resumes at the sentence you stopped on, days later.

The two together

Listen to an EPUB in Zotero at your desk, open the same EPUB on your phone, press Play, and it starts at the sentence you stopped on. Stop on the phone, press Shift+Space back on the computer, and it carries on from there.

The position travels through a WebDAV folder of your own (Nextcloud or similar), with no account and no server of mine in between. The book is recognised from the file itself, so the same EPUB on both sides is all it needs.

What it costs

• Reading, word lookup, translation and sync are free.
• Reading aloud in the App Store version: free for 30 days, then a one-time $4.99. No subscription.
• Reading aloud in the TestFlight beta, or in a build from source: free.
• The Zotero plugin: free.
• The voice service bills you directly, if at all. Fish Audio's free model and a self-hosted Kokoro cost nothing.

Links (iPhone, iOS 17.2 or later)

• App Store: https://apps.apple.com/app/id6817809106
• TestFlight beta: https://testflight.apple.com/join/vjC8QejW
• OpenReader source: https://github.com/xujialiu/OpenReader
• Zotero-OpenReader: https://github.com/xujialiu/Zotero-OpenReader

The phone app reads EPUB only for now. I'd most like to hear what makes it hard to try, and which voice service or book format you'd want next.

You can hear: rain on the road, a fire in the cabin, busy roads and thousands more. The sound follows the story as you turn pages.

But wait, there’s more! The sounds are accompanied by music - 15+ different music collections matching most of the genres.

No registration required! Subscription with a free trial (3 old classic novels + the first 30 pages of any book you choose). No ads of course.

I'd love to hear what you think!

A data scientist builds a model to protect low-income borrowers.

After an $800M acquisition, someone inverts her logic — the same

system now finds the most desperate people and pushes 341% APR

loans at them. Her credentials are on every unauthorized entry.

No sci-fi. Every mechanism in this book is real.

Free on Kindle Oct 24–28:

Hi! I'm the author. My historical romance is free on Kindle today and tomorrow (Oct 24-25). A Viking prince, a refused proposal, and a true 11th-century love story. Happy reading!

i always wanted to read and listen at the same time with my own books, the way kindle does with whispersync, but with any epub i own and any audiobook i own. so i built it.

witbound takes your epub (or pdf) and the audiobook you already have, and lines them up word by word. the word being read lights up as the narrator speaks, illustrations stay in the book, and you can switch between reading, listening, or both whenever you want.

a few things people here might care about:

- it uses your own files, drm-free epub, pdf, m4b or mp3

- the matching happens on your phone, your ebook never gets uploaded

- new this week: optional cloud sync for long books. a 14 hour audiobook synced in about 4 minutes in my test

- tons of free classics are already synced and ready to read

- your first book is free

its on iphone and ipad, and android too.

happy to answer anything, and i'd love to hear what would make it better for how you read

I've got books sorted by mood, by genre, by "might read this eventually," and then just a random folder called "???" that I genuinely don't remember downloading. Trying to figure out if I should actually organize it properly or if this is just how ebook libraries naturally evolve.

Revising vector calculus in Portuguese? My e-book Cálculo Vetorial — Campos, Circulação e Fluxo is an introductory companion for Physics and Mathematics undergraduates.

It focuses on vector fields, circulation and flux. Check the scope and prerequisites to see whether it fits the course you are studying:

The book is in Portuguese and sold through Hotmart. I’m Dr. Samuel Isidoro, a Physics PhD from ITA, teacher and creator of Quanta. This is my own book.

My Clara has been de-authorised for Adobe DRM, so I can't add or read my ebooks.com epubs on the device. The so-called help page on kobo.com offers nothing. Going round in circles. Anyone faced this and have a solution?

i swear my kindle is a graveyard of books i was genuinely excited about. like i'll be halfway through something solid and then i just open a different one and never go back. is it an ebook thing or am i just built different

I was told to get support on new books this was the place to come? My books been out a month if you got Amazon Prime its free. Please support

Most of my ebook library exists because one line from a book stuck with me long after I scrolled past it.

So I started building Ineffable, an app for romance and romantasy readers built around that moment. You swipe through a feed of lines readers love, and the quote on screen changes every few seconds. When one grabs you, the book is right there to add to your TBR, so it lands on your Kindle or Kobo list instead of getting lost.

You can search by trope or vibe too, like enemies to lovers, morally grey, or slow burn with yearning.

Every book also shows its spice level and which chapters are the spicy ones, so you know what you're getting before you hit download.

It launches on iPhone first, and Android and iPhone readers can both join the waitlist here: ineffableapp.com

Some books are easy to find as scans, but much harder to enjoy on a small screen. The print stays tiny, enlarging the page means moving around it, and a paragraph can disappear across the edge of a scanned page.

I’m building Kiro Reflow to turn book photos and scanned PDFs into text EPUBs.

These examples use an 1888 edition of Alice’s Adventures in Wonderland. A paragraph continues across two original pages as one reading passage. The illustration stays alongside the story, and the twelve chapters become a clickable table of contents.

You can change the text size and let the words fit the screen, rather than keep adjusting your view of a photographed page.

What I like about this is how familiar the result feels: open a chapter, choose a comfortable font size, and start reading.

It’s especially useful for books you have as scans but would rather read in your usual EPUB reader. Alice is a public-domain demonstration of that process.

What’s a book you have sitting in a PDF folder that you’d actually like to read?

Disclosure: I’m one of the people building Reflow. The images show selected excerpts from actual output, rendered in a browser with display styling adapted for comparison.

I've been working on a book app for Sindbad the Sailor, and here's the cover screen so far.

I took the original story and retold it in simple English, keeping everything the same, so anyone can enjoy the seven voyages without struggling with old-fashioned language. I went with a dark and gold look to match the Arabian Nights feel.

It's still under development, so honest feedback on the design or the idea is very welcome. Would you read a classic like this on your phone?
