In fact, the process of conversion involves just picking or selecting the document and clicking on Convert. It is one of the easiest apps to use when it comes to making conversions.
DjVu To PDF Converter is an app that lets you easily convert any DjVu file to PDF document.
But for the occasional djvu (especially if the source doesn't have color photos) this app is great. This app will likely need no introduction as it is popular djvu to PDF converter free download for android. See price drops for the Mac app DjVu To PDF Converter. When the image conversion complete, you can download your result file. You also can choose between different conversion options for optimizing your PDF. Then choose a format to convert and click the 'Convert' button. This free tool allows you to convert any DjVu to PDF simply by submitting the file. If you have lots of djvu files this app may be frustrating and you may want to pick a commercial app that does batch conversions. First, you need to add DJVU image file for convert: drag & drop your DJVU image file or click inside the white area to choose a file. I then switched the file to 'Black & White' (thankfully, my source was a book with b&w photos in it) and the resulting conversion (lossy, 30) took less than a minute, was only 64Mb, and the black text looked much better (the background was no longer dingy and yellowish from the original scan). Third attempt was a lossy setting of 30: resulting file was 550Mb and of acceptable quality (almost identical to lossless conversion), which was better but still a big file and a long conversion. I did a second conversion of the same file with lossy=70: it took around the same time to create the file, which was now 'only' 932Mb. I first tried using this app with a 32Mb djvu on my 2012 i7 Mac mini with 16Gb RAM: it took over 5 minutes for the conversion, and the resulting file was over one gigabyte! When choosing a lossy conversion you're provided with a slider scale from 0-150, whatever that means.
But you can get it to convert fast with better text if you choose the 'Black & White' option! This app does exactly what it claims to but it will take a long time to convert djvu documents, and the resulting pdf file size can be enormous.
