Hello everyone, PDF is a document format that we often deal with in our work. There are many software and websites related to this online, but many friends still don't know what tools to choose when they have relevant needs. So today, I will summarize various PDF needs for you and recommend the best tools 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, a multi-threaded password cracking tool. Most of these software use dictionary attacks, and the speed depends on the complexity of the password.
If you don't want to use software, you can also try the website ilovepdf, which has many functions. There are many similar websites on the market, but not many support PDF decryption. The website is also convenient, just upload the file and let it decrypt slowly. Once it's done, a download notification will pop up. However, 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 definitely Acrobat DC, after all, PDF is a format invented by them. 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 dàlǎo. 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's free, unlimited, and supports a wide range of formats, not just PDF. You can use it to convert various images, videos, audios, and e-books online. 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 it all. In short, for format conversion in the future, it is recommended to use it as the first choice.
Others#
If you have other needs such as reading, removing watermarks, or editing, if you want something simple, just use a software to solve all the needs, as mentioned above, Acrobat DC is recommended. If you want something more convenient and don't have many requirements, you can use the ilovepdf website or PDF24 Tools, which can meet both needs. Anyway, I suggest using a software to handle as many needs as possible, let's not install too many things.
