Checking your documents and writings for mistakes regarding spelling and grammar is easily done online. All you have to do is paste the text you want to check into a web service like and wait for it to be checked. Of course documents can be checked as well. When you’re writing an article or essay in Microsoft Word or OpenOffice, you can easily upload your DOC, DOCX, ODT, RTF or TXT document and get a thorough check. Even PDF text documents work!


What if you have a file that contains scanned pages though? Or even worse: an image containing text? can check text on an image as well. Thus, when you scanned a document as an image or snapped a photo of a PowerPoint slide, for example, you can check it for spelling and grammar mistakes as well. Following, we will show you how this is done – step by step and for free.

3. Browse your device or hard drive for the image file you want to check. Keep in mind that the maximum file size allowed for the upload is 8 MB. In case the result of the grammar and spelling check is dissatisfying, you can improve the result by setting the language. This is optional and as a default, our system tries to detect the language itself.


4. Click on “Check Text”.

5. Give the service a bit time to upload your image and convert it into a text that can be checked. This will be done quickly, depending on the file size of your image.


6. Check the result. As you can see below, the tool was able to interpret the text of our scan (right). The only thing missing was the en-dash.
