Adding Text to Your Document
Standard PDF viewers often treat files as read-only. If you want to add text to a PDF online free—whether you need to fill out a PDF form, leave a note, or label a diagram—you need to overlay a new text layer onto the page.
Drag and drop your document into our comprehensive PDF editor. Files are encrypted during upload and automatically deleted after processing.
Locate the "Text" or "Add Text" icon in the top toolbar. This activates the insertion mode.
Click anywhere on the page where you want the words to appear. A text box will generate, allowing you to start to type on the PDF immediately.
Use the context menu next to your text box to change the font size, color, and alignment so it blends cleanly with the rest of the page.

Can I Edit Existing Text?
Placing a new text box on a page is different from changing the words that are already there. If you need to fix a typo in a paragraph or delete an existing sentence, you will need to interact with the document's base layer. You can learn more about altering existing paragraphs in our guide on how to edit PDF content.
How to Add Text to a Scanned PDF
If your PDF was created by a scanner, it is essentially a photograph of a piece of paper. You won't be able to click directly into a blank line to modify the existing text layer. However, using the manual "Add Text" tool allows you to place a text box directly over the blank line. For more advanced handling of image-based documents, check our tutorial to edit scanned PDFs.
How to Add Text to a PDF on Mobile
Because ClonyPDF works entirely in the browser, the process remains exactly the same on your iPhone or Android device. Navigate to the tool, tap to upload your document, select the text tool from the condensed mobile menu, and tap anywhere on the document to write on the PDF using your device's native touch keyboard.
Common Issues When Typing on PDFs
Sometimes inserting a text box in a PDF doesn't work as expected. Here are the most common reasons why, and how to work around them:
- Password Protection: Some authors lock their files to prevent modifications. If the text tools are grayed out, check if the document requires a permission password to unlock editing features.
- Form Fields: If you are filling out an interactive form, simply clicking the blue or highlighted boxes will let you type. If the form isn't interactive, use the manual text box method mentioned above.
Next Steps
Once you've finished typing your information into the document, you might need to make other additions before finalizing the file. If the document is an application or contract, you may need to insert a logo or a scan of your signature. Read our instructions on how to edit a PDF and add an image for details on placing graphics.
When your document looks exactly the way you want it, it is crucial to ensure your new text layers are preserved properly upon export. Review our steps on how to edit a PDF and save to guarantee your formatting is locked in place.
Frequently Asked Questions
If you cannot type, the PDF might be a flattened image or scanned document without a text layer. You can bypass this by using the "Add Text" tool to place a new text box over the document, rather than trying to edit the existing text.
When you create a new text box, you can select standard fonts from the formatting toolbar. If the exact font isn't available, choosing a similar serif or sans-serif option is usually sufficient for forms and notes.
No. Adding a new text box overlays the text on top of the current page. It does not push or shift the underlying content, ensuring your original layout remains intact.
Some PDFs contain flattened text or scanned content. In those cases, you can add a new text layer or use a specialized PDF content editor to modify the base text.
