How I Figured Out Filling Forms and Signing PDFs in Foxit

Honestly, getting started with Foxit PDF Reader for filling out forms and signing was kinda confusing at first. It’s not exactly super obvious where everything is, especially if you’re new to it. The first thing I did was open the PDF—either through File > Open or just dragging the file into Foxit. Once it’s loaded, that’s when the fun begins. The tricky part was finding the “Fill and Sign” tools because sometimes they’re tucked away in weird menus. For me, it was under the Protect > Sign • Fill & Sign menu. In some updates, they’ve moved it, or it appears as a big button in the toolbar. Anyways, once you spot it, you’re halfway there. If it’s not showing up, check if your Foxit version is up to date—sometimes older versions hide features or disable certain menus.

Now, filling out forms? Pretty straightforward once you get the hang of it. To tick checkboxes, I selected the Checkbox tool—usually under Typewriter & Interactive Form controls—and just clicked where I needed it. Resizing was helpful because sometimes the default size was too big or small for the box. Typed text was easiest with the Typewriter tool—click where you want it, start typing, then drag it around to position just right. Be warned, though: sometimes the fields don’t auto-detect, especially if the form isn’t well-made. I had to run Form > Run Form Field Recognition manually. It’s a hit-or-miss, especially on complex forms. Also, don’t forget to zoom in Ctrl + + or with your mouse wheel—those tiny details are a lot more visible close up, and it helps with alignment.

Getting Signatures on Your PDFs

This part was a little more frustrating than I thought. To add a signature, you click on the Sign > Place Signature menu, then choose “Add.” The options let you create a digital signature by either drawing one with your mouse/stylus, typing your name and letting Foxit stylize it, or importing an image of your handwritten signature. After creating your signature, you just drag it onto the document, resize if needed, and position. The main thing I learned was that it takes a couple of tries to get it looking right, especially across multiple pages. If you plan to use the same signature often, save it in the Sign > Manage Signatures area—trust me, it makes life much easier next time you need to sign something quickly.

Adjusting the View for Better Reading & Editing

Foxit’s view options can be surprisingly useful. Night mode, for instance—found under View > Night Mode or with Ctrl + Shift + N—is super handy if you’re working late and don’t want to kill your eyes. It’s also called “Night Mode,” but honestly, it’s more like a dark theme for the document. Besides that, you can toggle Reading Mode or go full screen for undistracted reading. I found the split view feature in View > Split View to be a lifesaver when I needed to compare two pages side by side. You pick either Vertical or Horizontal split, and it just… works, even if it sometimes feels a bit laggy if your PC is doing too much.

Sometimes, I wanted a distraction-free space, so I hid the navigation pane via View > Navigation Pane. The options aren’t perfect, but if you’re careful, they work well enough. You can also adjust the zoom with Ctrl + + and Ctrl + -, but the split view really helps when you’re comparing or working on two parts of the same document without flipping back and forth.

Annotating and Marking Up PDFs

Comment tools in Foxit are pretty versatile. The Pen tool is good for quick sketches or marking up sections, while the Text Box lets you add comments directly on the page. I also used the Highlight tool to make key info stick out, and you can change the color and thickness of your highlights—try different colors for different stuff, it helps later when reviewing. It took me a bit to figure out that double-clicking a highlight opens up properties so you can tweak its look. Be aware: Foxit sometimes keeps your last used tool active, so if you switch to another, it might take a second to get used to switching back. Patience is key.

To underline or strike out, the same comment toolbar has those options—perfect for editing reviews or pointing out errors. I found that the more you play around with the tools, the more natural it gets. Also, the drawing tools like the Freehand Drawing are surprisingly precise, especially if you enable “Snap to Grid” or similar options for consistent lines.

Zooming in on Details or Cropping Output

This one took me a while to perfect. Foxit’s marquee zoom (drag a rectangle, and it zooms into that area) is way better than the global zoom, especially for signatures or tiny text. You activate it via View > Zoom > Marquee Zoom or by holding Alt and dragging with the mouse. It’s quick, and you get a close-up without losing view of the rest of the page. Be aware, though: it can sometimes be a bit finicky if your system is busy or if you don’t drag clean enough. Using this is much faster than constantly zooming in and out with Ctrl + +.

When it comes to printing only selected parts, I’d zoom into what I want, then go to File > Print. In the print dialog, set the Page Range to Current View. This saves paper and ink if all you want is a signature or specific section. Sometimes, I also saved this cropped view as a new PDF—by choosing Print to PDF—which was helpful for future use. Just be careful with the scale settings; I had to adjust the scale (like 120% or 150%) to keep clarity, especially for signatures or small annotations. Cropping with the marquee tool isn’t always perfect, but with a little practice, it’s a good way to get just what you need on paper or as a separate file.


Hope this helps — it took me way too long to figure some of this stuff out. Double-check that your Foxit is updated, your form recognition is enabled, and that your signatures are saved correctly before starting. Usually, the secret is in the menu labels or toggles—if something’s grayed out or missing, maybe update or reinstall. For me, the biggest reveals were discovering the form recognition and that marquee zoom, which saved me countless hours. Anyway, hope this saves someone else a weekend.
