Hello everyone, PDF is a document format that we often deal with in our work. There are many software and websites online for this purpose, but many friends still don't know which tool to choose when they have related needs. So today, I will summarize various PDF needs and recommend the best tool to solve them.
PDF Decryption#
The most famous one in this aspect is the PassFab series, which not only supports PDF decryption but also supports decryption for various office suites and compression packages. The only drawback is that it requires payment.
If you don't want to spend money, you can try this free and open-source PDFRip. It is a multi-threaded password cracking tool, and such software is usually based on dictionary attacks. The speed depends on the complexity of the password.
If you don't want to use software, you can also try the website ilovepdf. It has many functions, and there are many similar websites on the market. However, there are not many websites that support PDF decryption. The website is convenient, you can upload the file and let it decrypt slowly, and it will notify you when it's done. But please note that it can only remove the editing password set for the PDF document.
PDF Conversion#
Especially for converting to Word, PowerPoint, and Excel, the most famous software in this aspect is Acrobat DC, after all, PDF is the format they invented. The software is everywhere.
If you think the software is too large and it's difficult to run on your old device, you can use this PDFGear or the tool made by Wǔ Ài Dà Lǎo. They are both free and compact, specifically designed for converting between PDF and various file formats.
If you rarely need to convert files and don't like installing software, then this website called Aconvert is the only one I recommend. It is free, unlimited, and supports a wide range of formats. It's not just for PDF, you can also use it to convert various images, videos, audios, and e-books. For example, many websites now use the WebP image format invented by Google, but many traditional websites or software have not yet supported it. This website supports all of them. In short, if you need to convert formats in the future, it's the first choice.
Others#
For reading, removing watermarks, editing, and other needs, if you want something simple and a software that can solve all the requirements, then Acrobat DC mentioned above is the best choice. If you want something more convenient and don't have many requirements, you can use the ilovepdf website or PDF24 Tools, which combines both options. Anyway, I suggest using one software to handle everything, let's not install too many.
