How to Change Font Size in PDF in 5 Quick Steps
Here’s how to use Smallpdf’s PDF Editor to change your font size in a PDF file:
Step 1: Launch the PDF Editor and Upload Your File
Start by heading to PDF Editor. You’ll see an upload area where you can:
- Drag and drop your PDF file from your device.

To add new content to your PDF, hit the “Add Text” button in the top toolbar. Then, click anywhere on the page to place a new text box and begin typing.
Step 3: Change the Font Size
After clicking into a text field or text box, look for the toolbar that appears at the top of the PDF. Find the font size setting, labeled with a number like 12 or 14.
Click the upwards or downwards arrow to change the size of the font. The text will automatically resize on the document as you select the new value.
Step 4: Fine-Tune Your Layout
Once your font size is set, you can click and drag the text to reposition it on the page. This helps ensure your content fits neatly without overlapping elements.
If you need to remove a text box, click on it and press the trash icon. If you need to edit your font style or alignment, use the rest of the options in the toolbar.
Step 5: Download or Export Your PDF
Click “Download” in the top right corner of the screen to download the edited PDF to your device. You can also click “Finish” to export the document in different formats, share it, or print it.
