To extract text from an image, select the Text mode, select the preferred text language from the menu at the top of the screen, point the camera at the text you want to extract, and then tap the round Camera button.
When you tap Continue, Microsoft Lens extracts the text from the image and displays it on your screen. You can now Copy the text and Share it in any of the other apps on your Android device.
Extract Text from Images using the Windows 10 Photo Scan app
PDF (Portable Document Format) files extract the text information from a captured image. You can search the text contents of a PDF file and highlight or copy any part of the page with your preferred PDF Reader app.
OCR or Optical Character Recognition is also referred to as text recognition or text extraction. Machine-learning based OCR techniques allow you to extract printed or handwritten text from images, such as posters, street signs and product labels, as well as from documents like articles, reports, forms, and invoices. The text is typically extracted as words, text lines, and paragraphs or text blocks, enabling access to digital version of the scanned text. This eliminates or significantly reduces the need for manual data entry.
Intelligent Document Processing (IDP) uses OCR as its foundational technology to additionally extract structure, relationships, key-values, entities, and other document-centric insights with an advanced machine-learning based AI service like Form Recognizer. Form Recognizer includes a document-optimized version of Read as its OCR engine while delegating to other models for higher-end insights. If you are extracting text from scanned and digital documents, use Form Recognizer Read OCR.
Apart from the Windows OCR engine, Power Automate supports the Tesseract engine. This engine can extract text in five languages without further configuration: English, German, Spanish, French, and Italian.
You can also use the Tesseract engine to extract text from multilingual documents. To find more information regarding extracting text from multilingual documents, go to Perform OCR on multilingual documents.
There are many OCR tools online that will let you extract text from images on any device. All you need is a browser and an internet connection to start using this tool (on both PC and mobile). I have tried many online OCR tools, and New OCR gave the best results for all the images I used. The service is completely free and very easy to use.
Although it worked fine for most of the images I tested and correctly extracted text with minor formatting mistakes, it really messed up one of the receipt images. The font size and color was completely different from the image that made it look very ugly. Thankfully, such an error can easily be fixed by selecting all the text and choosing a default font.
There are many apps for Android that let you convert images to text. Not only that, but you can also scan text on the go as all Android phones have built-in cameras. Text Scanner is my favorite Android OCR app as it lets you extract text from images offline. It also offers unlimited scans for free in multiple languages.
There is a button at the top-right corner of the app to select images from the gallery and a button at the bottom-right corner to use the camera to take a text photo. Use any of these options to upload the photo, and the app will automatically process and show the extracted text. You can switch between text and image using the buttons at the bottom to compare them.
If you particularly want to extract text from images on the web, then a Chrome extension can help. I like two extensions for this purpose, Copyfish and Project Naptha. Project Naptha is my favorite among the two as it automatically makes all text inside the images on the web selectable.
If you want to scan and convert images on demand instead, then Copyfish is a much better option. After installing Copyfish, you can click on the extension button to open up a tool to select the location of the text you want to extract. Once the area is selected, Copyfish will copy a picture of the highlighted area in its interface and then use OCR to extract text.
The extracted text can be copied using a dedicated button. You can even translate it by using a button to open the text in Google Translate directly. For best results, make sure the image is open in the highest possible resolution, as Copyfish simply takes a screenshot of the image, so better image quality will offer more accurate extraction.
The tool comes with a trial version that gives access to all the features for 10 days. If you like the tool, you can buy one of the pro versions depending on your need. You can use Readiris to extract from images/PDFs saved on your PC, or take screenshots of any image and extract text from it.
Apart from extracting, you can annotate PDFs, add voice comments, split/merge PDFs, add watermarks, save scans online, convert text to audio, and much more. If you want both an OCR tool and a PDF manager, then Readiris is worth an investment.
If you want a cheaper OCR tool for mac, then Picatext is worth a try too. For just $3.99, you can extract text from saved images or new screenshots. The extracted text is automatically copied to paste anywhere easily, and you even have the option to select the default font.
Google has released a new application called Photo Scan, which uses OCR to extract text out of an image (scanned document or a simple photo with embedded text). It would be awesome if Windows 10 would have this feature out of the box, but at least users are able to download Photo Scan for free from the Windows Store.
You can create a PDF file directly from a paper document, using your scanner and Acrobat. On Windows, Acrobat supports TWAIN scanner drivers and Windows Image Acquisition (WIA) drivers. On Mac OS, Acrobat supports TWAIN and Image Capture (ICA).
Select this option only if you want to see the settings using the windows and dialog boxes provided by the scanner manufacturer. When the option is not selected, scanning starts directly with the settings specified in the Custom Scan or Configure Predefined Settings interface.
Select this option to convert text images in the PDF to searchable and selectable text. This option applies optical character recognition (OCR) and font and page recognition to the text images. Click the Settings icon specify settings in the Recognize Text - Settings dialog box. See Recognize text in scanned documents.
Lossless compressions can only be applied to monochrome images. To apply lossless compression to a scanned image, select one of these options under the Optimization Options in the Optimize Scanned PDF dialog box: CCITT Group 4 or JBIG2 (Lossless) for monochrome images. If this image is appended to a PDF document, and you save the file using the Save option, the scanned image remains uncompressed. If you save the PDF using Save As, the scanned image may be compressed.
Have you ever encountered information in a picture that you wanted to copy? An easy way to get that information without retyping it is to use Microsoft OneNote. It supports optical character recognition (OCR), so you can extract text from a picture, paste the text into an application, and edit it.
Besides extracting text from pictures, you can extract text from screenshots that you capture. This is useful if you want to capture text that you cannot normally copy by highlighting and pressing Ctrl+C. For example, you can take a screenshot of a drop-down box on a web page or a list of files being displayed in Windows Explorer, and then extract the text from the screenshot. To do so, follow these steps:
OCR works best with images of printed or font text, rather than handwritten. Still, if you prefer taking handwritten notes, you can just snap a photo and upload them to OneNote. Later, if you need to locate a specific detail, you can search OneNote for a specific term or date written in those notes and it will easily find it, even in an image.
Say you have a document that you need to convert into text format. You could spend several minutes typing the document out in Word, or you can snap a photo of the document and let Photo Scan pull the text from the image.
The process of capturing an image to convert to a text file is simple. Either open an existing image, paste a picture from your Windows 10 clipboard (a screenshot for example) or launch the camera and snap a picture of a document. A thumbnail image fills the top portion of your display and the app begins to pull the text from the photograph. The thumbnail image has three button commands to paste, refresh and close the image view. Information on the image's resolution and location can be revealed by tapping the arrow displayed at the bottom of the thumbnail.
As far as the accuracy of the text conversion, I found Photo Scan to be a mixed bag of results. If I had to place a percentage on the conversion success rate, it would fall in the 85-90% range. It works great on business cards but can struggle with formatting line breaks correctly. I did find that italicized images can throw off the spelling and you also need to be careful not to photograph a document and have anything written in the background. I placed a handout on my desk calendar and the app picked up on some of the printing that was on the calendar.
Among several other features, the more robust Evernote Personal plan ($7.99 a month or $69.99 a year) includes syncing unlimited devices, 200-megabyte maximum note size, document scanning, and searching for text inside images, documents and PDFs.
Have you ever wished you could pull text from photos and videos? Apps like Google Lens and Office Lens offer some level of interactivity, but thanks to a helpful touch of artificial intelligence, iPhone and iPad owners (and Mac users) have built-in support with Live Text.
Introduced in iOS 15, the feature allows you to aim your device's camera at a sign, document, or any other physical object and extract the image's text (supported languages include English, Chinese, French, Italian, German, Portuguese, and Spanish). It even works on images stored in your camera roll and websites with images that contain text. With the upgrade to iOS 16, you can also pull text from video, and even grab objects from both photo and video captures. 2ff7e9595c
