How to translate manga with OCR tools for reading on my phone
Hello again, fellow weebs! Today I bring you a super useful guide on how to translate manga with OCR tools so you can read them on your phone, PC, etc, even if the manga hasn't been translated yet.
If you have ever landed on a raw manga chapter with no scanlation, no translation, just the original Japanese staring back at you, you know exactly how frustrating it is to have no idea what is happening. The good news is that you do not need to wait for a fan translation or learn Japanese to read untranslated manga on your phone. OCR tools can do it for you, right on your screen, in real time.
OCR stands for Optical Character Recognition. In simple terms, it means your phone's camera or a dedicated app can look at text in an image — like the dialogue in a manga panel — and convert it into actual readable text that can then be translated. It is the same technology that lets you scan a receipt or a business card, just applied to manga speech bubbles.
Here is how to set it up on Android and iOS.
How to Translate Manga on Android
Android has the widest range of options for manga OCR, including some tools that are deeply integrated into the reading experience itself.
1. OCR Manga Reader
OCR Manga Reader is the most dedicated solution available for Android, built specifically for reading and translating manga panels. You point your camera at a speech bubble, it reads the Japanese text, and it spits out a translation. No copy-pasting, no switching between apps — it is all handled in one place.
It supports offline translation for Japanese, which is a big deal if you are reading on the go without a reliable connection. The interface is a bit barebones, but what it lacks in polish it more than makes up for in accuracy and speed. If translating raw manga on Android is your primary goal, start here.

2. Kaku
Kaku takes a different approach. Instead of being a standalone manga reader, it works as an overlay that sits on top of whatever app you are already using. You activate it, draw a box around any text on your screen — a speech bubble, a sign, anything — and it translates it instantly. This makes it incredibly versatile because it works with any manga reading app you already have installed.
It is one of the most practical OCR tools for everyday use because it does not lock you into a specific reader. Use it with your favorite app, your browser, or even screenshots. If Kaku is not showing up on the Play Store in your region, APK versions are available through trusted community forums.
3. TachiyomiJ2K-OCR
If you are already using Tachiyomi or one of its forks to read manga, TachiyomiJ2K-OCR is the most seamless option available. It is a community-built fork of the popular TachiyomiJ2K reader that has OCR translation baked directly into the manga reading interface. No switching apps, no overlays — you just long-press a panel and get your translation.
Because it is a community fork and not on the official Play Store, you install it via APK from GitHub. It is the closest thing to a fully integrated manga reading and translation experience on Android, and for anyone who already lives in the Tachiyomi ecosystem, it is a no-brainer.
How to Translate Manga on iOS
iOS options are fewer but equally powerful, and they are generally more polished thanks to Apple's native OCR framework built into the operating system.
1. Kantan Manga
Kantan Manga is the most purpose-built iOS app for reading and translating manga, and it shows. The app is designed from the ground up around the manga reading experience, with OCR translation that works panel by panel without breaking your flow. It handles vertical Japanese text, which is notoriously tricky for generic OCR tools, far better than most alternatives.
If you are on iPhone and want something that just works without any tinkering, Kantan Manga is your best starting point. Download it, open your manga, and start reading.

2. OwlOCR
OwlOCR is a general-purpose OCR tool for iOS, but it is exceptionally good at handling manga text thanks to its accuracy with Japanese characters and its clean, no-fuss interface. You screenshot or import an image, select the text area, and get your translation. It is fast, reliable, and works offline for supported languages.
Where OwlOCR shines is flexibility. It is not locked into manga specifically, so you can use it for any Japanese text you encounter — subtitles, game screens, social posts, whatever. If you want one OCR tool on your iPhone that handles everything, this is it.
Tips for Getting the Best Translations
OCR accuracy depends heavily on image quality. Blurry scans, low-resolution images, or panels with a lot of visual noise behind the text will produce worse results. Whenever possible, use clean, high-resolution manga files for the sharpest output.
Vertical Japanese text can trip up tools not designed for manga. If you are using a general OCR app and getting garbled results, switch to one of the dedicated options listed above — they are built to handle the way manga text is actually formatted.
Keep in mind that machine translations are good but not perfect. For nuanced dialogue, character-specific speech patterns, or anything that relies heavily on tone, an official or fan translation will always be more accurate. OCR tools are best used for getting the gist quickly, reading raws before translations drop, or exploring untranslated series that may never get a full release.
Final Thoughts
Knowing how to translate manga with OCR tools is genuinely a superpower for any serious reader. It opens up thousands of untranslated chapters, lets you read raws the moment they drop, and frees you from waiting on scanlation schedules that can sometimes take weeks or disappear entirely.
Whether you are on Android and want something fully integrated like TachiyomiJ2K-OCR, or on iPhone and want the dead-simple experience of Kantan Manga, the tools are there and they work. Pick the one that fits how you already read and you will never look at a raw chapter the same way again.
