Simple and Easy cloud operation
For users who rarely use PDF files, the system usually does not install the corresponding PDF editing software, at this time without the installation of software can operate the cloud services become the best choice.
First through the browser to open the Http://smallPDF.com application site, click on the upper right corner of the "Chinese" button, in the pop-up menu to choose "English." When the Web interface is translated into Chinese, click the PDF to JPG button in the Web page. Click the "Select File" button in the pop-up page and select the PDF file to convert in the pop-up dialog box (Figure 1). At this point the page will ask the user is "extract a single picture" or "Convert all pages", if the user clicks the first item, the cloud server began to upload files and the image of the extraction operation.
When the picture is finished, it will show the extracted picture, and the one you need to download it (Figure 2). Of course, you can click the "Zip file Download" button, you can take all the extracted picture files to download to the local hard disk.
Small tip:
You need to be reminded that the Extract single Picture command extracts only the pictures in the PDF file, which does not include text content. The "Convert all Pages" command converts the entire page in a PDF file, including a text picture, to a picture, so the user needs to choose according to their needs.
Flexible and convenient local operations
The advantages of cloud operations are self-evident, but the problem is that there are often file size limitations, so sometimes it has to be done on the local system. However, it is not necessary to use specialized software, the use of Photoshop, such as common image processing software can be completed.
Run any version of Photoshop First, and then click Open on the File menu and select the PDF file to be processed in the pop-up dialog box so that the software can parse all the pages in the PDF file. With the mouse and SHIFT key to select the page to be converted, and then click the "Good" button will pop up a grid window, and then click the "Good" button can be selected to load the page into the software (Figure 3).
In theory, just click on the "Save as" command on the "File" menu and save the page as the picture format you want. But if you do, the converted picture will be about half the size of the original. So first you need to click on the "Image" menu "image size" command, in the pop-up dialog box "pixel size" in the value of magnification, and then click the "Good" button to save as the operation (Figure 4). Next, set the quality to best in the JPEG Options dialog box that pops up so that the picture is the same size as the original page.

In addition to saving as a picture, you can also take advantage of the software's "snapshot" or "screenshot" features. The selected area is automatically saved to the Clipboard, pasted into any one of the picture editors, and then saved.
