了解AI 玩转AI All-in-one PDF tool: PDF24, data merging, splitting, batch extraction, format conversion—suitable for integrating data to build a knowledge base.

Why does the moderator recommend this tool to newcomers? Because many AI tools only use PDFs as a knowledge base, and in China most of our PDF tools are paid, with almost none free. So this tool is also essential for us. It can help you merge downloaded PDFs, split files that are too large, and extract images from them in batches.

The moderator recommends that you do not install it on the C drive. Later, when there is more data, sometimes you may accidentally save too much to the C drive by default, and you won’t be able to stand it.
