How to Write and Edit on a PDF

From reviewing contracts and filling out forms to collaborating on project proposals, knowing how to write on a PDF is now a baseline skill for modern business. These documents anchor almost every professional workflow, appearing in everything from legal agreements to internal approvals. They remain the gold standard for sharing files that must retain their layout across any device. However, static files become a hurdle when you need to annotate, update old information, or input specific data. To turn these rigid documents into flexible workspaces, a reliable PDF editor is essential.

If you’ve ever wondered how to type on a PDF without printing, scanning, and re-uploading (we’ve all been there), you are in the right place. This guide walks through the main ways to write and edit PDFs using Foxit PDF Editor, from adding new text and making edits to annotating documents and handling scanned files.

How to Add and Edit Text on a PDF

For any number of reasons, you may have to redo some text in a PDF. Foxit PDF Editor provides all the tools that you need to easily make changes to text.

Here’s how to write on a PDF file using Foxit step-by-step:

1. Open the PDF file in Foxit PDF Editor by clicking on the “File” menu, then selecting “Open.”
2. Click on the “Edit” tab in the top menu bar.
3. Select the “Edit Text” tool. If the PDF contains live, searchable text, you’ll be able to click on any existing text in the PDF and start typing to edit it. If it’s a static PDF, which is essentially an image, see the steps below.
   
   Note: Clicking on a scanned or image-based PDF with Edit Text command, a message prompts where you can click Recognize Text to run OCR, or click Settings to specify OCR settings before recognizing text. To not show the prompted message again, you can go to File > Preference > Editing > uncheck the option “Alert when there’s no editable text when using ‘Edit Text’ tool”.
   
4. If you need to add new text to the PDF, click on the “Add Text” tool. This will allow you to click anywhere in the document and start typing. Whether you need to type over a PDF to insert headers, add explanations, or create new paragraphs, the Add Text tool gives you full control over placement and formatting.
5. To change the font, size, color, or other text properties, select the text you want to edit and then open the “Format” tab in the right-hand pane. From there, you can make your changes.
6. Once you’ve finished editing the PDF, save your changes by clicking on the “File” menu and selecting “Save” or “Save As.” You can then share the edited PDF as needed.

The whole process takes just a few clicks, and your document maintains its professional formatting throughout.

Note that some features in Foxit PDF Editor may require a paid license.

How to Annotate PDFs with Comments and Highlights

Sometimes you don’t need to change the actual text in a document. Maybe you just need to add your thoughts, flag important sections, or leave feedback for colleagues. That’s where annotation tools come in handy.

Foxit PDF Editor includes a full suite of annotation features that make collaboration simple. You can add comments directly to specific sections of text, highlight key passages in different colors, draw attention to important details with shapes and arrows, or use sticky notes to leave longer feedback without cluttering the document itself.

To annotate a PDF in Foxit, open your document and click on the “Comment” tab in the top menu. From there, you’ll see options for highlighting, underlining, adding text boxes, inserting sticky notes, and more. Click your preferred tool, then click or drag on the document where you want to add your annotation.

These tools are particularly useful when you’re reviewing contracts, marking up drafts, or providing feedback on proposals. Team members can see exactly what you’re referring to without having to decipher vague email notes. Plus, all annotations can be easily reviewed, replied to, or removed as your document evolves.

How to Fill Out and Sign Forms in a PDF

PDF forms are everywhere—employment applications, client intake forms, tax documents, service agreements. Being able to fill these out digitally saves time and keeps everything organized.

With Foxit PDF Editor, you can type directly into form fields, check boxes, select options from dropdown menus, and add your signature without printing a single page. The software automatically detects interactive form fields, so you can simply click and start typing.

For documents that need your signature, Foxit’s eSign capabilities let you create a digital signature that you can insert anywhere in the PDF. You can type your name, draw your signature with your mouse or trackpad, or upload an image of your handwritten signature. Once created, you can reuse it across multiple documents, making the signing process quick and consistent.

Digital signatures aren’t just convenient—they’re also legally binding in most jurisdictions, making them perfect for contracts, agreements, and official forms. Learn more about Foxit’s eSign and PDF capabilities.

How to Write and Edit Text in a Scanned PDF Using OCR

Here’s a common frustration: you receive a scanned PDF, which is essentially just an image of a document, and you need to edit the text. Without the right tools, you’re stuck retyping everything manually.

Optical Character Recognition (OCR) is a software process that enables images of printed text to be translated into machine-readable text. Foxit PDF Editor can detect whether a PDF file is scanned or image-based and make corresponding suggestions to initiate OCR when opening a scanned or image-based PDF.

To convert a scanned PDF into editable text:

1. Click Convert > Recognize Text > Current File, in the Recognize Text dialog box, and specify the page range you need.
2. Choose the language used in your document. You can select multiple languages as well.
3. In the output type, check Editable Text to enable the image text to be edited with Foxit PDF Editor. Then click OK to recognize the text.

Once OCR is complete, you can write in the PDF just like you would with any other document—editing existing text, adding new content, or fixing errors. This feature is a lifesaver when you’re dealing with older contracts, archived records, or any document that was originally created on paper. It eliminates the tedious work of manual retyping and ensures accuracy when digitizing physical documents.
