RuneManga vs OpenToon for manhwa and webtoons
OpenToon, the phone app, next to RuneManga: chapter links, languages, editing, coins or a pass, and what happens to your images. Checked November 2026.
Short answer
OpenToon is a phone app for iPhone, iPad and Android: paste a chapter link or upload images, and its AI translates the speech bubbles into more than 50 languages, with every bubble editable and chapters saved on the device for offline reading. After a free trial it is paid with coins or a $9.99 monthly pass. RuneManga works in the browser and as a browser extension, takes ZIP, CBZ and PDF files, erases the old lettering and fills in the background, and has a $0 Free plan with 20 credits a day.
| Feature | RuneManga | OpenToon |
|---|---|---|
| WebApp upload | Yes. Add images, a folder, a ZIP, a CBZ or a PDF (50 to 500 pages at once depending on the plan, 20 MB each), correct the result in Edit mode, and download single pages, a ZIP or one PDF. | No. OpenToon is a mobile app for iPhone, iPad and Android. You paste a chapter link into the app or upload images. |
| Browser extension | Yes, in the Chrome Web Store (Chrome, Brave, Opera), Edge Add-ons and Firefox Add-ons. It translates pages right on the sites you read: an R button per page, Auto mode while you scroll, show original, Translate an area, Edit image and a ZIP of the page's translations. | No browser extension. The app has its own link importer and viewer. |
| Languages | From Japanese, Korean, Chinese, English and six more languages (or auto-detect) into 93 languages, including English, Spanish, Portuguese, Turkish, French, Chinese, Japanese and Korean. Arabic and Thai output is experimental. | Korean, Japanese, Chinese and English as sources; more than 50 target languages. |
| Bubble-aware typesetting | Yes. Lettering in speech bubbles, caption boxes and text on the art is erased, the background filled in and the translation fitted in its place. Sound effects stay as drawn. Edit mode, in the WebApp and the extension, lets you move, restyle and rewrite the text. | Its AI translates the text inside the speech bubbles and keeps the comic's format; tap a bubble to see the original or edit the line. Its pages do not say how the original lettering is removed. |
| Colorize | BetaYes, our own AI colorizer for black-and-white pages, in the WebApp and the extension, on every plan. It keeps the line art, screentone and lettering; the colors are its guesses, so results vary. 1 credit a page, 2 together with Translate. A page already in color comes back as it is, and its color credit is given back. | Not mentioned on its pages or App Store listing. |
| Translation engine | RuneLingua, our own AI translator for manga dialogue, on every plan, Free included. A few languages it does not cover well yet use another translation service. You can also connect your own AI key (OpenAI, Anthropic, Google Gemini, DeepSeek, xAI or OpenRouter). | Not named. OpenToon says it uses the same AI as its sister app OpenNovel; its privacy policy describes third-party OCR, machine translation and LLM providers. |
| Pricing | Credits: 1 a page to translate or to colorize, 2 for both. Free at $0: 20 credits a day, claimed on the site. Supporter ($2.99, 1,000 a month), Pro ($4.99, 2,500) and Ultimate ($9.99, 5,000) are on sale now. Credit packs never expire. See the pricing section for the available packs. | A free trial for new users (its length is not stated), then coins or the OpenToon Pass. A page costs 1 coin, 1.5 for manga; packs start at 2,500 coins for $5.99. The Pass is $9.99 a month for unlimited translations under fair use. |
| Privacy and retention | Pages are processed on RuneManga's servers; only the text found on the page goes to the translation engine. Jobs are deleted about an hour after they finish and are not used for training. | Images and the text read from them go to third-party OCR, translation and AI providers. OpenToon says it does not store uploaded images or translated chapters on its servers; chapters are saved on your device. |
| Sign-up needed | Yes for the WebApp: a free sign-in with Google, Discord or an emailed link, no card. | Not stated on its pages. Its privacy policy describes sign-in with Google or Apple. |
When RuneManga is the better fit
- You read on a computer and want pages translated in the browser, on the sites you read.
- You want a free plan rather than a trial: 20 credits a day, claimed on the site, plus 30 at sign-up.
- You want to translate a ZIP, a CBZ or a PDF and download the result as pages, a ZIP or one PDF.
When OpenToon is the better fit
- You read on your phone and want an app that imports a chapter from its link.
- You want chapters saved on the device to read again offline.
- You read a lot and want one monthly price: the OpenToon Pass has no page count, under fair use.
