HTML (or HTM), also known as hypertext markup language, is an application under the standard general markup language. “Hypertext” means that the page can contain non-text elements such as pictures, links, and even music and programs.

III. Summary

In the above, the editor introduced three tools that can identify and extract the HTML code in the picture. The following is a brief summary of the experience of using these three tools, hoping to help you choose an operation method that suits you. .

Considering the functional configuration:

The three methods introduced in this article all have OCR technology. It is because of this technology that these three methods are more effective in identifying and extracting HTML codes in pictures. Although both are format conversion tools, they have slightly different functional configurations. The advantage of Renee PDF Aide over the other two tools is that the operation process is more stable. You can complete the identification and extraction of image content offline, while Renee PDF Aide Don’t worry about failing halfway. In addition to being able to identify and extract HTML codes in pictures, Renee PDF Aide also supports PDF format conversion and basic editing, with comprehensive functions.

Considering security:

Using the FreeFileConvert online tool and Google Docs are both online operation tools, and the image files need to be uploaded to the corresponding network server, which has certain security risks. The difference between the two is that Google Docs is endorsed by the powerful Google company, and the file security is more reassuring, but the security of the two is not as good as that of Renee PDF Aide, because all operations of the software are performed locally Complete, support offline operation, no data will be intercepted or stolen.

Consider from the conversion result:

Renee PDF Aide adopts more advanced OCR technology, supports multi-language recognition, and the conversion results will be better; while both Google Docs and FreeFileConvert also have OCR technology, but the files opened by Google Docs will only keep the files The text of the file will not retain the original layout style of the file, which is one of its shortcomings. If you need to preserve the typesetting style of the source file, it is recommended to use the other two methods first. As for FreeFileConvert, it does not support many OCR languages, so if you need to recognize files in multiple languages, the recognition results of this method will be worse.

You can choose and use according to the above analysis and combined with your actual needs.
