A powerful optical character recognition (OCR) extension to capture and convert images to text

Image from store OCR - Image Reader
Description from store This extension adds a toolbar button to your browser to perform OCR. When this action button is pressed, it allows the user to select a region in the currently active window. The extension captures the area and tries to recognize text inside this region using the internal powerful OCR engine (Tesseract engine). This extension uses the "tesseract.js" library that supports more than 100 languages, automatic text orientation, and script detection. This extension loads the JS library on the page and removes it when you are done. This way, there is no long-term resource usage. Notes: 1. On the first run, the extension might take a few minutes to fetch the training data from the internet. Since this resource is cached, all subsequent calls are going to be fast. 2. Optical character recognition (OCR) is slow, so this extension displays a progress bar for each detection module. 3. This extension does the OCR process offline. There is no server-side interaction. It only fetches the language training database once. 4. This tool can be used to extract the text content out of images, PDF documents, Powerpoint slides, or extract the content of a web page when user-section is forbidden. 5. If the text extraction confidence is low, the extension inverts the image and retries (particularly useful on the dark theme) 6. If the text extraction is not accurate, you can modify the image and drop it into the interface to retry. Change Logs: Version 0.2.4: Supports browser-level page zooming and OS-level screen zooming Adds image language detection (still beta) (slow operation)

  • (2023-08-18) Glen Stewart: Fabulous implementation. Works fine with Vivaldi. Solves a problem where a web page used Javascript to disable text copy for a VIN that was shown on a car sale web page. Why retype? Thanks so much!
  • (2023-07-20) Jewel Deng: works perfectly for browser images!
  • (2023-07-19) Konstantin K.: Вроде работает норм. Иногда распознает в картинках лишние символы, которых там нет, и которые надо удалять вручную. (‘&A‘“A:. = el)
  • (2023-07-13) Shah Samad: it works people! it works well and fast! problem is no instruction. so here it is: click on icon. use mouse just like you do with snipping tool (windows). that's it! a window will pop up instantly to show progress and results. beautiful!

  • (2023-06-27) J D: Erro de permissão e nenhum site dá certo
  • (2023-06-05) 銀翼之龍: 無法工作
  • (2023-05-31) Danny Flood: As the previous reviewer has said, it is not working. Clicking the icon and there is no response from the extension.
  • (2023-05-22) David Fred Schneck: No documentation. Not sure how to even run it. Clicking the Chrome extension button doesn't do anything. Nothing on the web site to tell you how to initiate a read. Might be a great app, but lack of instruction makes it useless for me.
  • (2023-05-15) Александр 'Производственная компания Дарвин': Дякую це відмінний додаток. Очікую на оновлення з можливістю розпізнавання рукописного тексту (гугл об'єктив вже вміє)
  • (2023-05-01) Domenico: Non funziona, "SecurityError: ..." e nessuna opzione disponibile! Rimossa
  • (2023-04-08) Samuel Beech: It can be kinda slow sometimes, and it can be slightly inaccurate occasionally, so you just have to double check it (by inaccurate I mean it may think an I is a J when using a weird font) but otherwise it works fine.
  • (2023-03-23) Демьян Попов (Пасхальный крол): Из проверенных мной расширений - самое стабильное и точное из минусов не слишком быстро определяет текст но это значительно лучше чем переписывать.
  • (2023-03-23) Bárbara: No funciona con nada, sale error en cada intento.
  • (2023-03-21) JiangYing: It errors: SecurityError: Failed to execute 'open' on 'CacheStorage': An attempt was made to break through the security policy of the user agent. errorHandler @ chrome-extension://bhbhjjkcoghibhibegcmbomkbakkpdbo/data/engine/index.js:23 (anonymous) @ chrome-extension://bhbhjjkcoghibhibegcmbomkbakkpdbo/data/engine/tesseract/tesseract.min.js:2 t.onmessage @ chrome-extension://bhbhjjkcoghibhibegcmbomkbakkpdbo/data/engine/tesseract/tesseract.min.js:2
  • (2023-03-21) Philip Schlaepfer: Acceptable, but it's prone to some corruption like most OCR programs are. It's not as good as the apple gallery OCR, but pretty good
  • (2023-03-21) Milo Chen: how to fix it? ***securityerror: failed to execute 'open' on 'cachestorage': an attempt was made to break through the security policy of the user agent***

  • (2022-09-08) Sobon George: Not working - stuck on "loading language traineddata"
  • (2022-08-08) Tom Tom: Not perfect but it works. So far tried it on Google Play Books. Have to make some edits but overall, does what it does. Copy Fish doesn't work as well but it works much better once you download something else on Top. I'm trying to avoid that. This app does it.

  • (2021-12-29) Hiếu Nguyễn Ngọc: Very good extension, fast scan and supported many language. I would like to add the option of commonly used languages
