How to Edit a PDF: Text, Images, Pages & More

Quick answer 

To edit a PDF, or modify a PDF’s text, images, and pages, open it in a PDF editor and choose the tool that matches the change you need. Use Edit Text to change existing words, Add Text to insert new content, and image tools to add, move, resize, or replace graphics. If the PDF is a scan, run OCR first so the image-based text becomes editable. You can edit PDFs on Windows, Mac, mobile, or in a browser. 

Can you edit a PDF document? 

Yes. A PDF is not automatically read-only. With a full PDF editor, you can change PDF content directly, including existing text, new text, images, and page order, and save the edited file without returning to the original Word, Excel, or design document. 

The exact method depends on the PDF. A digitally created PDF usually contains editable text and objects. A scanned or image-based PDF may require optical character recognition (OCR) before you can edit its text. 

How to edit a PDF with Foxit PDF Editor 

For most document changes, the fastest approach is to edit the PDF directly. Open the file in Foxit PDF Editor, choose an editing tool, make your changes, and save a new copy if you want to preserve the original. 

How to edit existing text in a PDF 

  1. Open the PDF in Foxit PDF Editor.
  2. Choose Edit > Edit Text.
  3. Click the paragraph or text you want to change.
  4. Type, delete, or replace the text. Use the Format panel to adjust the font, size, color, spacing, and other text properties as needed.
  5. Save the edited PDF. Use Save As if you want to keep the original file unchanged.

When you edit paragraph text, Foxit can reflow the line as your changes reach the text boundary, making routine text corrections feel closer to editing in a word processor. 

How to add text to a PDF 

  1. Choose Edit > Add Text.
  2. Click where you want the new text to appear or drag to create a text area.
  3. Type or paste the new text.
  4. Use the Format panel to match the font, size, alignment, line spacing, and other formatting to the document.

Adding text is useful when you need to insert a note, fill in missing information, add a label, or place new copy on a page without changing an existing paragraph. 

How to add or edit images in a PDF 

PDF editing is not limited to text. You can also insert new images and work with image objects already in the document. 

  • To add an image: choose Edit > Add Images > Image From File, select the image, and place it on the page. 
  • To edit an image object: select the image and use the available object or image editing controls to move, resize, rotate, copy, or delete it. 
  • To keep layouts consistent: check the image’s size and position after editing, especially in forms, reports, and branded documents. 

How to edit a scanned PDF with OCR 

If you click text in a scanned PDF and nothing is editable, the page may be an image rather than actual text. OCR converts image-based characters into machine-readable text, so you can search, select, and edit them. 

  1. Open the scanned or image-based PDF in Foxit PDF Editor.
  2. Choose Edit > Edit Text. If Foxit detects that the page is image-based, choose Recognize Text when prompted.
  3. Select the correct OCR language and settings if needed.
  4. After OCR finishes, review the recognized text and make your edits.

OCR accuracy can vary with scan quality, handwriting, unusual fonts, skewed pages, and low-resolution images. Review important names, numbers, and formatting before sharing the edited file. 

How to edit a PDF online 

An online PDF editor is useful when you need to make changes from a browser or cannot install desktop software. Open the PDF in Foxit PDF Editor Cloud, make your edits, and save or download the updated document. 

Browser-based editing works well for quick changes and access from different devices. For complex formatting, large documents, scanned files, or advanced object editing, a desktop PDF editor may give you more control. 

How to edit a PDF on Mac 

Mac users can make basic annotations in Preview, but changing existing PDF text, editing objects, or working with more complex layouts generally requires a full PDF editor. 

  1. Open the PDF in Foxit PDF Editor for Mac.
  2. Choose Edit > Edit Text to change existing words or Edit > Add Text to insert new text.
  3. Use the Format panel to match the surrounding text and paragraph styling.
  4. Use image and object editing tools when you need to add, move, resize, rotate, or remove graphics.
  5. Save the PDF or save a copy under a new file name.

How to edit a PDF on Windows 

The Windows workflow is similar: open the document, choose the Edit tools, change the text or objects you need, and save the result. You can also right-click supported text and use editing commands to get to common actions more quickly. 

For scanned files on Windows, enable or run OCR before editing image-based text. This helps with scanned contracts, forms, receipts, and archived documents. 

How to edit a PDF in Microsoft Word 

If you prefer to work in Microsoft Word, you can convert the PDF to a Word document, make your edits, and then save or export the finished file back to PDF. This method can work well for text-heavy documents, but complex layouts, tables, fonts, forms, and graphics may shift during conversion. 

  1. Convert the PDF to Word using a PDF-to-Word conversion tool.
  2. Open the converted DOCX in Microsoft Word and make your changes.
  3. Review the layout carefully, especially page breaks, tables, images, and fonts.
  4. Save or export the edited document as a PDF.

If preserving the original PDF layout is important, editing directly in a PDF editor is the safer option. 

Which PDF editing method should you use? 

For most changes, edit directly in a PDF editor. Use OCR first for scans and convert to Word only when you need to rewrite a text-heavy document extensively and don’t need the original layout preserved exactly.

Why can’t I edit my PDF? 

If a PDF will not let you edit text or objects, one of these issues is usually the cause: 

  • The file is a scan or image-based PDF and needs OCR before the text can be edited. 
  • The PDF has security permissions or password protection that restrict editing. 
  • You opened the file in a PDF reader or browser viewer that supports viewing and annotation but not full content editing. 
  • The text uses a font that is not available on your device, which can limit how the text can be changed. 
  • The document contains flattened or unusually structured content that is harder to edit as separate objects. 

Before converting the file to another format, check whether OCR, permissions, or the editing application itself is the real issue. 

Tips for editing PDFs without breaking the layout 

  • Save a copy before making major changes. 
  • Match the surrounding font, size, line spacing, and alignment when replacing text. 
  • Keep replacement text close to the original length when the layout is tight. 
  • Review pages after moving or resizing images and objects. 
  • Run OCR before editing scanned text instead of covering the scan with new text boxes. 
  • Check links, forms, signatures, and interactive elements after large edits. 
  • Review the final PDF at normal zoom and print preview before distributing it. 

Frequently asked questions about editing PDFs 

How do I edit a PDF? 

You can edit a PDF by opening it in a PDF editor, choosing the tool for the change you need, such as Edit Text, Add Text, or image tools, then saving the updated file. Foxit PDF Editor handles all of these from one workflow. 

Can I edit a PDF without the original document? 

Yes. A PDF editor lets you change many text and image elements directly in the PDF, so you do not always need the original Word, Excel, PowerPoint, or design file. 

How do I edit text in a PDF? 

Open the file in a PDF editor, choose Edit Text, click the paragraph or text object, and make your changes. Then review the formatting and save the updated PDF. 

How do I add text to a PDF? 

Choose an Add Text tool, click where the new content should appear, type or paste the text, and format it to match the document. 

Can I edit a scanned PDF? 

Yes, but you usually need OCR first. OCR converts the image-based text in a scan into searchable, selectable, and editable text. 

Can I edit a PDF on a Mac? 

Yes. Basic Mac tools can handle annotations, while a full PDF editor can change existing text, add text, and edit images or other objects in the PDF. 

Can I edit a PDF online? 

Yes. A browser-based PDF editor can handle many common changes without installing desktop software. The exact editing features available depend on the online editor and the document. 

Can I edit a PDF in Word? 

Yes. Convert the PDF to Word, edit the DOCX, and save it back to PDF. This works best for text-heavy files; complex layouts can change during conversion. 

Why is text in my PDF not editable? 

The text may be part of a scanned image, the PDF may have editing restrictions, or the file may be open in a viewer that does not support full editing. Try OCR for scanned content and check the document permissions. 

Does editing a PDF change the original file? 

It depends on how you save it. Use Save As or save a copy if you want to preserve the original PDF and keep a separate edited version. 

Edit PDFs without rebuilding the document 

Editing a PDF directly can save time when you only need to correct text, add content, update an image, or make changes to a document you no longer have in its original format. For scanned files, OCR can turn image-based text into editable content before you make revisions.
