How to Add Text To PDF
Sometimes you need to add a note, fill in a missing field, label a diagram, or stamp a status like 'APPROVED' or 'DRAFT' directly onto a PDF without converting it to another format. Adding text directly to a PDF preserves the original layout while layering your additions on top. SublimePDF's text tool gives you full control over font, size, color, and exact placement.
Follow the step-by-step instructions below, then use the free tool directly — no registration or download required.
Open Tool →How to Add Text To PDF — Step by Step
Upload your PDF
Open the Add Text to PDF tool and upload your document. The editor loads all pages with zoom controls so you can position text precisely.
Click to place your text
Click anywhere on the page to create a text insertion point. A text box appears where you can type your content. Drag the box to reposition it exactly where you need it.
Format the text
Select your font (Helvetica, Times, Courier, and more), set the size in points, and choose a color. Use bold or italic styles for emphasis. For watermark-style text, reduce the opacity.
Add text to multiple pages
Use the 'Apply to page range' option to stamp the same text (like 'CONFIDENTIAL' or a date) on multiple pages at once, with the same position and formatting on each page.
Save and download
Click 'Apply' to flatten your text additions onto the PDF. The added text becomes part of the document. Download the final file.
Pro Tips
- 💡 To create a visible watermark, use large text (48pt+), set the color to light gray, and reduce opacity to 30–40%. Position it diagonally across the center of the page.
- 💡 Match the font of existing text in the PDF for seamless additions—zoom in on the original text to identify the font family and approximate size.
- 💡 For form-like PDFs without fillable fields, zoom in and carefully position text boxes directly over the blank lines to simulate filled-in fields.
- 💡 Use the alignment guides that appear when dragging text to center your additions or align them with existing content.
