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)

  • (2023-03-21) 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***

  • (2022-12-10) Albert: Not working - stuck on "loading language traineddata".
  • (2022-11-26) NIKHIL Gaikwad: Excellent product !!!!!
  • (2022-11-22) Infinity Knight: It will be better if you add "file://*/" in host_permission so in local pdf file, images we can use OCR.
  • (2022-11-17) Madu Santus: Usei tempos atrás e funcionava legal. Precisei dele hoje, baixei em outro computador, mas desta vez não funcionou.

  • (2022-09-28) Lucas Andrade: Cumpre de forma excelente ao que se propõem e de forma simples e rápida sem ficar tentando te vender qualquer coisa. Uma excelente ferramenta!
  • (2022-09-13) Daniela Rodriguez: no funciona con youtube
  • (2022-09-10) XxMrFiresxX: use to work but now it doesn't work on youtube
  • (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.
  • (2022-07-24) Ankit Rohilla: Works perfectly
  • (2022-07-22) Martin Brown: It works well for me. No more typing in text from graphics!
  • (2022-07-18) Yoni Sade: It has more misses than hits... (tried to OCR Simplified Chinese characters)
  • (2022-07-15) ChalkyMuffin 969: No es perfecto, tiende a equivocarse con algunas letras sobre todo si es código pero funciona.
  • (2022-07-08) Alexandre Alexiades: I really love this extension. It does exactly what it says. Just select a slide, image or video with text on it and it will extract and generate the text so you can copy to clipboard.
  • (2022-07-01) QTu Le: english below Xài dễ lắm, có hỗ trợ cho tiếng Việt mà free nữa hơn cha bb nhiều mà còn free có cái hơi lag xíu khi quét va lâu hơn xíu mà nói chung xài được hơn nhiều á nha, khuyên mng nên dùng cái tiện ích này English: Very simple to use, working with Vietnamese, recommendation for everyone use it
  • (2022-06-29) Lester Ilustrisimo: not working it stuck on loaded language traineddata
  • (2022-06-27) Eduardo José Giménez Suárez: Exelente, funciona perfectamente!
  • (2022-06-25) Tanya Bondarenko: Accuracy is too poor and completely useless
  • (2022-06-22) Andrea Solis: Esta herramienta cumple con su función prometida
  • (2022-06-15) G L: É preciso saber usar, existe uns macetes. Por exemplo, se quiser capturar o texto de uma imagem é preciso capturar por partes às vezes, se a imagem tiver mensagens divididas por partes e você tentar capturar tudo dá erro, nesse caso capture por partes que você conseguirá capturar praticamente tudo que está na imagem.
  • (2022-06-13) RJ: Retyping all of those text on picture manually is faster than using this
  • (2022-06-07) Marcos Yam Garcia (Marcos): Doens't work at all. Never gets even simple text right and results are all inconsistent.
  • (2022-06-07) Damien L: This saved me so much time copying from unselectable PDFs
  • (2022-06-03) Chug Lands: It doesnt even work with constant error messages about permissions or whatnot, not a single clue on the website as to what it could be
  • (2022-06-02) Jhexts: Llega a fallar
  • (2022-05-28) Devilbager: it's completely free and can detect for example the letter G even if half of it is covered by a cursor. I got this because blackbox which is a similar and way worst extension started making people pay 30$ a month even though its already very inaccurate.
  • (2022-05-26) VAHA: works. Would love to see better UI
  • (2022-05-18) Eduardo Rodrigues: Funciona bem, pode melhorar um pouco
  • (2022-05-14) Mohamed Anan: Not Working anymore!
  • (2022-05-08) Mari Mar!: Perfect translation text from an image For the copied to the text - select in the upper right corner (open in Google Translator) https://translate.yandex.ru/ocr example: https://screenrec.com/share/HP7WCcRqnI or https://prnt.sc/Rq8KDvnKrSOD
  • (2022-05-08) Ahmd Eisa: I want to copy a code from youtube video and it didn't work
  • (2022-04-23) BIG Smoke: Sometimes never runs. When it does run, it glitches out and half of it is just random letters.
  • (2022-03-30) Levan Matskhonashvili: It is a great tool, Very useful.
  • (2022-03-12) Attiq Khan: Thanks, solved my problem
  • (2022-02-05) 元無名: 不能讀取繁體中文!垃圾軟件
