After downloading PDF files, we can use PDF software to read, edit, and convert the ebooks. One software I frequently use is Cisdem PDFMaster. It integrates functions such as reading, creating, editing, annotations, converting, compressing, encrypting, signing, etc. It has a clean interface and well-organized, placing frequently used features on the home page for easy access.
In terms of PDF editing, it can edit the text and images of the PDF itself, When editing it will ensure that modifications do not alter the original structure and framework. Colors and font sizes can be modified in the right toolbar.
Besides editing, you can also use it as a PDF reader. It provides several default reading modes, you can switch to an eye-protection mode by one click. It also supports color changes to match the computer system, with dark mode available for night use.
When reading a PDF file, It supports split-screen viewing, allowing you to compare and read the same or different files simultaneously, which is useful when you need to reference content from different parts of the document without flipping back and forth.
If you like to take notes while reading, this software supports it too. You can use it to make annotations, comments, and highlights, after making all the annotations you can export the notes directly from the PDF file as separate notes. You can also search for notes by keywords.
Its conversion function is also outstanding, allowing you to quickly convert PDFs to Word, PPT, Excel, CSV, etc. Especially when converting tables, it ensures the consistency of tables and data, which is really convenient. If you have large batches of PDF to be converted, you can use the batch conversion function, it has no limits on the number or frequency of conversions, and the converted files will keep the layout and fonts.
Websites giving free PDF documents and e-books are of great value to everyone, where we can read the books online or offline and use the documents for our work.
