To access your recently viewed PDFs, use the Recent Files option on the Start Page.
All of the viewing options are located in the bottom toolbar.
There are four ways in which your PDF can be viewed: single page view, single page continuous view, two page view, and two page continuous view.
Rotating PDF Pages
To rotate PDF pages, use the Rotate buttons to either rotate the PDF clockwise or counterclockwise.
Each click rotates the PDF by 90 degrees in the chosen direction.
Zooming in and out
You can zoom in and out of your PDF manually by clicking on the Plus and Minus buttons.
Alternatively, use the drop-down menu to select how big or small you want the PDF to appear.
Other adjustable viewing options include Actual Size, Fit Page, Fit Width, and the ability to view the PDF at 5% to 400% of its original size.
Under the Options button on the main toolbar, you can customize your viewer preferences.
You can opt to read and apply Document viewer preferences or to use default Application viewer preferences. If you check the latter, you will have to set page layout and zoom options that will be applied to every document opened in Slim PDF.
If you don't want to scroll through your PDF, you can use the navigation buttons to move through the pages easily.
From left to right, the four buttons allow you to return to the first page, move to the previous page, move to the next page, and go to the last page.
If you want to go to a specific page in your PDF, you can go to the page by manually typing the specific page number in the box.
Alternatively, you can use the Hand tool from the main toolbar to navigate around your PDF document.
In the left-side panel, there are 3 distinct tabs: thumbnails, bookmarks, and attachments.
Page thumbnails are miniature previews of the pages in a PDF. Use them to quickly jump to a selected page. You can reduce or enlarge page thumbnails in the active PDF document through the right-click menu or the Thumbnails drop down menu.
You can jump to bookmarks applied to an active PDF document by clicking on them in the Bookmarks panel. Further options are available through the right-click menu or the Bookmarks drop down menu.
If a PDF has files attached to it, they will appear in the Attachments panel. You can open or export the file attached by using the right-click menu or the Attachments drop down menu.
Viewing multiple PDFs
To open and view more than one PDF at a time, simply open your PDFs using the Open button from the main toolbar.
All PDFs will be presented as separate tabs in the navigation bar.
Here you can switch between your PDFs and arrange the order of the tabs.
Searching a PDF
You can search for specific information in the PDF you are viewing using the Search option.
Simply type your query into the Search box and hit enter. You can also use the options next to the search box to make your search case sensitive and/or whole words only.

You will then be able to Paste the text into another application.
Taking a Snapshot

Inserting Annotations to PDF
Slim PDF reader enables you to insert 10 different annotations to your PDF: sticky note, link, stamp, highlight, underline, squiggly, strikethrough, caret, attachment, and watermark.
Link annotation allows you to insert a link to an external webpage or to a page within the PDF document. Click on the page and drag the selection rectangle to apply the link. To follow the link, hold ALT and left click it.
When you select the Attachment annotation, a dialog window will pop up to let you browse for the file you wish to attach. Click on the page where you want the Attachment Icon to be displayed. Note that you can open and export the attached file through the Attachment tab in the left-side panel.
The Watermark dialog offers you a range of customization options. First, choose an existing image file and scale percentage or input plain text and select font, size, alignment, spacing, and color. Then, customize the Appearance (opacity and rotation), the Page margin, the Position of the watermark and the Page Range across which you want your watermark to appear. You can also turn your watermark into a template (a .wmkt file extension) and apply it to another document.
To insert a specific annotation, click on the desired tool and add it to the page.
In the properties section, you can customize the icon, color, and opacity of the added annotation.
Slim PDF Reader also allows you to leave your comments and feedback for others to review. Simply type them in the Comments section below.
If you made changes to your PDF and you want to save those changes, use the Save button on the main toolbar.
Use the Save As button if you want to save the modified PDF under a different name.
To revert or reimplement any changes you made or undid to the document, use the Undo and Redo buttons from the main toolbar.
Verifying Digital Signatures
If you receive a PDF file that has a digital signature attached to it, you can use Slim PDF Reader to verify whether the digital signature is valid or not.
To reveal information about the digital signature, click on the Signature icon in the right-side panel.
Note that the color of the highlight in the right side panel and the lock icon on the navigation bar will give you an indication of the signature's status:
