In this article, you will learn:

The use of PDFs is becoming a common practice that is used in many businesses. This is attributed to the rise of digital technology in nearly all geographies of the world. PDFs are the most convenient and safest way of sharing documents that retain the formatting and layout of the original document. The users are also able to access the files on any operating system be it Windows or Mac. And if the editor is compatible with many platforms, it can be viewed on any software as well. Two of the major PDF viewers include WPS PDF and SlimPDF. They both have their own set of benefits and drawbacks.

There are a number of factors that set both PDF viewers apart. WPS PDF is a document processing software that is used to create, edit, and manage PDF files. It is a product of Kingsoft, which is a Chinese software company that also provides and manages the WPS Office suite. The Office suite includes all the basic Office tools including, Word, Spreadsheet, and PowerPoint.

SlimPDF is a lightweight PDF reader that offers a number of services to users besides PDF conversions. Users are able to perform the basic editing functions on the platform. However, for users to be able to decide between the two, a WPS PDF comparison with SlimPDF is made to give an elaborate and clear difference between the two.

1. Features

Both WPS PDF and SlimPDF offer a range of comprehensive features for managing, creating and editing files, some of which are highlighted below.

  • Advanced Editing Features

WPS PDF offers an extensive range of creating and editing documents, allowing users and creators to edit their documents with complete ease and comfort. These features include the ability to edit, manage, modify, delete, and add texts and images to a PDF document. WPS PDF also allows users to create customized watermarks, headers, and footers. There are several formatting and layout options that allow users to create documents without having to compromise on the presentation. WPS PDF also offers an extensive range of annotation tools, which include highlighting, underlining, and strikethroughs. This is particularly helpful to students, teachers, and businesses. A team of users can also use WPS PDF at the same time by collaborating in real time and being able to see the edits the other users make.

SlimPDF is a lightweight PDF editor that is recognized mainly for its simplicity and ease of use. The viewer is developed by investintech.com and only allows SlimPDF the only basic editing capabilities. These features include adding texts, images, and shapes to a document, which is not as comprehensive as WPS PDF.

  • Security Features

Oftentimes, documents are shared over various platforms and it is important for the users to maintain the confidentiality of the documents. Some of the security features provided by WPS PDF are password protection, digital signatures, and permission management. By adding a password to the file, the users want to transfer, they are limiting access to their documents. To have access to the document, a password must be put in to be able to edit, open, print, copy, or modify the documents.

SlimPDF offers sufficient protection to the documents as well. The editor allows users to add passwords to their files to enable certain users to be able to access the file. This security feature alone is not enough to maintain the confidentiality of the document. SlimPDF lacks in certain areas when it comes to security features, compared to WPS PDF.

2. File Size Compression

Regardless of how big the size is of the PDF document, WPS PDF is able to compress it without compromising on the quality of the file. This feature is particularly useful to people who are transferring files over to different platforms that do not support large files. It significantly reduces the file size making it easier for users to be able to upload and send the document.

Although SlimPDF is incredibly file compatible and can be shared over various platforms and software, it does not offer a similar level of convenience when it comes to file size compression. SlimPDF is able to reduce the size of files however the technology is not as advanced as WPS PDF.

3. Multi Language Support

WPS PDF is a globally recognized PDF editor and thus ensures that their support is not only of superior quality but is offered over various different languages. This allows users to be able to create and convert documents in their preferred language. The application supports over 50 languages, making it convenient for users to work with documents where they are able to produce maximum outputs. For international businesses or organizations that are working with various different documents in different languages, would prefer WPS PDF as their choice of PDF editor.

SlimPDF is not lagging behind when it comes to offering multi language support. However, their service may be a little limited given that it does offer language support in as many languages as WPS PDF.

4. Conversion and Editing Capabilities

Individuals or businesses who are working with PDF files on a daily basis need to be able to convert the files into other formats. PDF editor users prefer working with documents that are easy to annotate and edit. WPS PDF is just a tool for users who want their editor to offer a wide range of features, which mainly include converting PDF files into other formats, annotating, and creating fillable PDF forms. Further, WPS PDF allows one to work confidently while having blind trust in the application.

SlimPDF, on the other hand, does not offer a similar level of conversions or editing. SlimPDF is an extremely simple and lightweight PDF editor, and since it was made to be an editor, the remaining features don’t perform as efficiently. Therefore, if someone wants to use the editor for their personal use, where they just need to open the file, the application is simple and does a sufficient job.

5. User Interface and Customization

WPS PDF reader has an incredibly intuitive and easy-to-use interface. The customization option allows users to be able to adjust the features according to their needs. The minimalist yet modern approach to the layout allows users to be able to adjust to the application quickly.

The application has a modern and intuitive interface making it easier to navigate. The different viewing modes such as single page, continuous, and thumbnail view gives the readers the ease and comfort of viewing the files, which not a lot of PDF editors offer.

SlimPDF is an incredibly lightweight editor which only enables it to support the basic features. The interface is simple, modest, and intuitive. Anyone who is starting off with documentation, should consider SlimPDF since it doesn’t take a lot of space and offers the basic features for viewing any document. The application also does not offer any kind of customization as WPS PDF, however it does offer some of the viewing modes which includes single-page, and continuous view.

6. Compatibility and Integration

WPS PDF offers support for multiple platforms which includes Windows, Mac, Linux, iOS iPhone, and Android while allowing seamless integration with other WPS Office products. This makes editing and creating much easier since users are able to work online or offline on their choice of software and platform without compromising the quality of the output.
