There are many situations where you may want to extract text from an image file. The image format does not matter; you can easily convert JPG, PNG, TIF, WEBP, and more.
Scans: If you scan articles, papers, receipts, invoices, or other documents, they may be saved as images.
Screenshots: Taking a screenshot of a page usually creates a PNG or JPG image.
Photos: To better follow a presentation, speech, or conference, it is often easier to take a quick photo of the slides and then focus on listening to the speaker.
To work with the text, search for keywords, copy and paste quotes, or store paperwork digitally, a text document is more practical than an image file.
