A method is recommended below. Although the conversion software needs to be registered, it can be used 10000 times without registration! !
PDF is a very popular electronic document format. Abroad, it has almost become the de facto standard of electronic documents. With the increasing exchanges between China and foreign countries, it has gradually become popular in China. PDF files have their own special reader-Acrobat Reader, but Acrobat Reader is huge, and the latest Chinese version 5.0 has more than 20 MB. Some PDF documents have undergone some special processing, so it is impossible to copy the text in the document and it is not allowed to print, which brings us a lot of inconvenience. I recommend the PDF tool, which can convert PDF files into HTML, TXT and BMP. PDF Tools is a * * * software, the download address is/pdf _ PS/pdf2txt/pdftools _ setup.exe, and the current version is v 1.2. First, the conversion method of PDF tool To run the PDF tool, click the Tools menu. There are three choices, namely "PDF2HTM", "PDF2TXT" and "PDF2BMP". The default choice is "PDF2HTM". In fact, no matter which format you choose to convert to, the conversion method is the same, and the work interface has not changed. Now let's convert a PDF file into an HTM file. Execute the Open command in the File menu, select the PDF file to be converted in the Open PDF File dialog box that appears, and click the Open button to open the Save As dialog box. After setting the saving path for the generated HTM file, click "Save" and the program will start conversion. Click the Pause or Close button to pause or stop the conversion. The converted HTM file can be viewed directly with IE. Although converting PDF files into TXT files has the advantages of small size and convenient editing, I don't recommend it. First, many PDF files contain tables or pictures, which will be lost after being converted into TXT files. Secondly, the author found that PDF tools can only effectively convert PDF files in pure English. If the converted content contains Chinese, garbled code may appear after conversion. The pdf tool will save every page in the PDF file as a BMP image, that is to say, as many pages as there are in the PDF file, as many BMP images will be generated. The generated BMP file is very clear and the browsing effect is excellent. Its only disadvantage is that the converted file is too large, with an average of about 2 ~ 3m per BMP file. If you convert a document with hundreds of pages, it will take up a lot of disk space, so it is recommended to convert all BMP files into JPG after the conversion is completed. Usually we can browse these pictures with ACDSee and other picture viewing software. Second, the parameter settings of the PDF tool Some friends may ask: What should I do if I only want to convert some pages in the document? In fact, the PDF tool already contains related operations. Execute the "Preferences" command in the "File" menu, open the parameter setting dialog box of PDF Tools, click the "Page Range" list box, select "Selected Page", and enter the starting page number and ending page number to be converted in the page range input box on the right. In Output Options, you can set the size and quality of the output image file. This setting is mainly used to convert PDF to HTM, and you can use the default setting in general. If "View after conversion" is selected, relevant programs will be automatically called to open the generated files after the conversion is completed. Then, if there is a PDF file, which file format should it be converted into? In my humble opinion, it is better to convert PDF into HTML format, because the effect of converting pdf into HTML is very good, and the viewing method is close to Acrobat Reader The most important thing is that the generated file size is not very large. If you are facing a PDF file that you don't know the content, it will be safest to convert it into HTML format.
