How to use Copyfish 🐟
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.
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 open in a new tab. That makes it easier to verify larger screenshots, as it avoids the scrolling.
Work with local files
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:
Input language shortcuts
Do you often need to switch between OCR languages? 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
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 repeatable 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 PDF 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 that are 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, and then use your favorite translator extension inside the Copyfish window on it.
Working with PDF
Copyfish works with PDF... exactly the same way as with normal websites.
Desktop Text Capture (Chrome only)
To trigger the desktop capture, right-click the Copyfish icon, select Desktop Text Capture. Then Google Chrome prompts you for permission to show a desktop or application screenshot in the browser [This selection happens locally in your browser, nothing is sent back to any server!]. Now that the image is displayed in your browser, everything works as usual: Click the Copyfish icon in the toolbar and select the text to extract, and Copyfish does its work.
