Copyfish: Copy, paste and translate text from any image, video or PDF.

How to use Copyfish?

  • 1. Install the extension and click the Copyfish icon in your Chrome browser.
  • 2. Select the area with the text (image, video, html5, ajax - Copyfish works with any input)
  • 3. Done! Copyfish extracts the text from the image, displays and translates it.

Important: If you get the "Unable to capture screen. Please try again when the page has loaded" error after the update, please uninstall and reinstall Copyfish. This will fix the issue. But if it still does not work, please contact us. Sorry about this issue. The good news is that improved web page screenshots and a new desktop screen capture feature will be available soon.

OCR’ed Text Overlay

Visualize the quality of the extracted text in seconds. Copyfish displays the OCR result in red on top of the original text in the image. We call this text overlay. And if you double-click the screenshot, a copy of it opens in a new tab. That makes it easier to verify larger screenshots, as it avoids scrolling.

Work with local images and PDF

You can drag & drop local images or PDF on your browser window and use Copyfish on these, just like you would with images on a website. For this to work, you need to allow Copyfish to access file URLs in the Chrome extension settings:

Allow access to file URLs in Chrome. This settings is not available and not needed for Firefox as it allows access to file URLs by default.

Input language shortcuts

Do you need to switch between OCR languages often? Then use Input OCR Language Shortcuts. Copyfish allows you to add up to three OCR languages as shortcut to the user interface.

For language learners

There are many translator addons available, but they only work with plain website text. Text inside images, in tricky Javascript/AJAX or in movie subtitles on Youtube or Youku is unreachable for them, but not for Copyfish. And if you want, Copyfish also translates the text for you right away. Extract text from videos - and translate it.

Especially for the subtitle translation use case, Copyfish has the “Do OCR” repeat feature: Mark the area of the subtitle once and then use the “Do OCR” repeat button to grab the text from this area repeatedly as you watch the movie. That function was inspired by the Chinese Pinyin subtitle translator app. Copyfish replaces this app with a cross-platform solution.

Tip 1: Using a small screen? -> Click the blue Copyfish title bar to shrink the Copyfish dialog. This hides the screenshot part of the Copyfish user interface.

Tip 2: Copyfish plays nice with all other translator extensions. So if you prefer to use your favorite tool, just disable the built-in translation.

How to Translate Texts with Copyfish

One reason to extract text from images or PDFs is to translate them. For that Copyfish has a built-in translator. But sometimes you may want to use more specialized translation tools, like the Google Translate extension or even extensions custom-built for one language like the Zhongwen Popup Dictionary for Chinese translation. Copyfish supports them all, just turn on the Support popup dictionaries switch.

The Support popup dictionaries switch allows (translator) extensions to show their popups in the foreground. This feature works also with the new Desktop text capture of Copyfish (-> Right-click on the Copyfish icon). So now, you can grab text from the desktop, then use your favorite translator extension inside the Copyfish window on it.
