Online OCR is an online OCR service that can recognize the texts and characters from scanned files and images. It requires no software installation, what you need to do is upload the file (not exceeding size of 5MB) as guided, choose the language and output format(Word, Excel or Text), then "Convert" to start the OCR process. Once finish, a download link will be offered to download the converted file.

Optical-character recognition (OCR) was the name we gave to extracting text from images. But the term has gone out of favor as software increasingly and automatically tries to identify text in an image and make it searchable and, often, available for copying.

OCR (optical character recognition) enables you to convert typed, printed or handwritten text into searchable and editable data from scanned PDFs or photos of documents. To perform OCR on Mac, you can use dedicated OCR software. Also, apps such as OneNote have an OCR feature. Some OCR tools are available as apps, which you can install on your computer and smartphone. And some are web-based services. This article will focus on free OCR tools available for macOS.

Called OCR Scanner with LEADTOOLS SDK at the Mac App Store, OCRApp is an easy-to-use free OCR app to perform optical character recognition on scanned PDFs and images. This free OCR for Mac supports five languages including English, Spanish, French, German and Italian.

Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo (for example the text on signs and billboards in a landscape photo) or from subtitle text superimposed on an image (for example: from a television broadcast).[1]

Early versions needed to be trained with images of each character, and worked on one font at a time. Advanced systems capable of producing a high degree of recognition accuracy for most fonts are now common, and with support for a variety of digital image file format inputs.[2] Some systems are capable of reproducing formatted output that closely approximates the original page including images, columns, and other non-textual components.

Early optical character recognition may be traced to technologies involving telegraphy and creating reading devices for the blind.[3] In 1914, Emanuel Goldberg developed a machine that read characters and converted them into standard telegraph code.[4] Concurrently, Edmund Fournier d'Albe developed the Optophone, a handheld scanner that when moved across a printed page, produced tones that corresponded to specific letters or characters.[5]

In the late 1920s and into the 1930s, Emanuel Goldberg developed what he called a "Statistical Machine" for searching microfilm archives using an optical code recognition system. In 1931, he was granted USA Patent number 1,838,389 for the invention. The patent was acquired by IBM.

OCR is generally an "offline" process, which analyses a static document. There are cloud based services which provide an online OCR API service. Handwriting movement analysis can be used as input to handwriting recognition.[14] Instead of merely using the shapes of glyphs and words, this technique is able to capture motions, such as the order in which segments are drawn, the direction, and the pattern of putting the pen down and lifting it. This additional information can make the end-to-end process more accurate. This technology is also known as "on-line character recognition", "dynamic character recognition", "real-time character recognition", and "intelligent character recognition".

Software such as Cuneiform and Tesseract use a two-pass approach to character recognition. The second pass is known as "adaptive recognition" and uses the letter shapes recognized with high confidence on the first pass to recognize better the remaining letters on the second pass. This is advantageous for unusual fonts or low-quality scans where the font is distorted (e.g. blurred or faded).[22]

Palm OS used a special set of glyphs, known as "Graffiti" which are similar to printed English characters but simplified or modified for easier recognition on the platform's computationally limited hardware. Users would need to learn how to write these special glyphs.

Crowdsourcing humans to perform the character recognition can quickly process images like computer-driven OCR, but with higher accuracy for recognizing images than that obtained via computers. Practical systems include the Amazon Mechanical Turk and reCAPTCHA. The National Library of Finland has developed an online interface for users to correct OCRed texts in the standardized ALTO format.[32] Crowd sourcing has also been used not to perform character recognition directly but to invite software developers to develop image processing algorithms, for example, through the use of rank-order tournaments.[33]

Accuracy rates can be measured in several ways, and how they are measured can greatly affect the reported accuracy rate. For example, if word context (basically a lexicon of words) is not used to correct software finding non-existent words, a character error rate of 1% (99% accuracy) may result in an error rate of 5% (95% accuracy) or worse if the measurement is based on whether each whole word was recognized with no incorrect letters.[36] Using a large enough dataset is so important in a neural network based handwriting recognition solutions. On the other hand, producing natural datasets is very complicated and time-consuming.[37]

Recognition of cursive text is an active area of research, with recognition rates even lower than that of hand-printed text. Higher rates of recognition of general cursive script will likely not be possible without the use of contextual or grammatical information. For example, recognizing entire words from a dictionary is easier than trying to parse individual characters from script. Reading the Amount line of a cheque (which is always a written-out number) is an example where using a smaller dictionary can increase recognition rates greatly. The shapes of individual cursive characters themselves simply do not contain enough information to accurately (greater than 98%) recognize all handwritten cursive script.[citation needed]

UPDF is the best OCR software on Mac that you might come across. By using optical character recognition (OCR), UPDF is able to convert scanned PDFs to any other format in a way that is both quick and accurate. There are over a dozen distinct conversion options available for converting PDF files to a variety of formats supported by Microsoft Office, as well as images, HTML, Text, and other file types.

Using PDF OCR X, you can convert photos and PDF files into text that may be accessed on many other devices in the future. It allows for fast and easy conversion. Optical character recognition (OCR) technology is the app's strongest suit since it allows it to retrieve all of the text contained inside a picture. Additionally, the application may save the extracted text to a TXT file that can be accessed from a variety of devices, including smartphones and tablets.

When you want to convert printed text or handwriting into a digital copy, you don't have to do it manually. You don't even have to spend a fortune on professional tools. We'll show you the best OCR (optical character recognition) programs that convert images into text for free.

Use the default keyboard shortcut WinKey + Q to activate the OCR process. You can then use the mouse to select the portion you want to capture. Hit Enter to trigger the optical character recognition. The captured and converted text will appear in a popup and, by default, will also be available in the clipboard.
