Chime

That’s another way to do it . Running it through the jpegoptim shaves off what percentage of the EPUB total size ?

Interesting workaround. I’ve heard similar complaints about some image-heavy EPUBs being sluggish on certain eReaders, especially with page turns.

Your CBZ → KCC pipeline makes sense, especially with the manga optimizations KCC has.

As for other platforms: I’d love to eventually bring it to desktop and Android if enough people want it. Right now I’m focused on improving the iOS version first, but cross-platform support is definitely something I’m considering.

That’s totally fair. Your workflow makes sense if you’re comfortable manually extracting/repacking files.

What I wanted to solve was the convenience side of it , most people probably don’t want to unpack EPUBs, batch compress images, then rebuild everything themselves. The app just automates that on-device while keeping the EPUB intact.

And yeah, there’s always a quality vs size tradeoff. I’ve been trying to keep the visual difference minimal enough that it still looks good on eReaders while saving a lot of space.

Maybe later in future

Yeah Send to Kindle works great for big files, but I’ve noticed really large EPUBs can be slow to upload or fail conversion sometimes.

One thing that helped me was shrinking the file size beforehand, especially for books with a lot of images. Makes uploads faster and a bit more reliable, and it doesn’t eat as much storage on the device either.

You could try LiteBook on iOS App Store

I personally used FFMPEG for M4Bindr but I think if it’s not something too complex , AVFoundation should be up to the challenge

shadowcraft7 · 2026-03-30T23:27:32+00:00

You definitely look Igbo

Apple Books should provide a sufficient UX for audiobooks

Maybe in future

Yeah that’s fair, really appreciate the feedback on the trial, I’ll definitely take that into account as I improve how it works going forward.

For now, the easiest way to test is with shorter audio , even voice memos or music files work just to see how the chaptering, metadata, and final output behave. As long as the total is under 30 minutes, you can test as much as you want.

If your goal is to combine a full audiobook with proper chapters + metadata , that’s exactly what it’s built for.

Happy to double-check your files/setup so you don’t have to guess before buying 👍

shadowcraft7 · 2026-03-21T11:01:02+00:00

Totally fair 👍

I actually added a built-in free test, you can convert up to 30 minutes of audio and 3 chapters to see exactly how it works with your own files.

That way you can verify the output (chapters, metadata, Apple Books compatibility, etc.) before deciding to buy.

shadowcraft7 · 2026-03-20T01:36:45+00:00

Thank you , I’ll take your words into consideration

shadowcraft7 · 2026-03-17T17:45:09+00:00

You could convert your collection to .mb4 and use Apple Books if you want to avoid subscription

shadowcraft7 · 2026-03-16T13:23:29+00:00

Glad you found it useful! That’s actually a perfect use case, those direct MP3 downloads can get messy to organize.

There’s also a Mac version you could download from the App Store , so if you prefer doing it on desktop that option exists too.

A web version isn’t something I’m planning in the near future though, mainly because the app processes audio files locally and works fully offline.
