Use freehand drawing tools, add shapes, or highlight text. Perfect for marking up documents for review.

Add Signatures

Draw your signature or upload a signature image. Use our dedicated Sign PDF tool for more options.

Method 2: Convert to Word, Edit, Convert Back

For extensive text editing, converting to Word format often works better:

  1. Use PDF to Word converter
  2. Open the Word file and make your edits
  3. Use Word to PDF to convert back

💡 Best For

This method works best for text-heavy documents. Complex layouts with tables, columns, or images may shift during conversion.

Method 3: Using Preview (Mac)

Mac users have a built-in option:

  1. Open the PDF in Preview
  2. Click the Markup toolbar button (pencil icon)
  3. Use tools to add text, shapes, signatures
  4. Go to File → Export as PDF

Limitations: Can't edit existing text, only add new content.

Method 4: Using Microsoft Edge

The Edge browser has built-in PDF annotation:

  1. Open the PDF in Microsoft Edge
  2. Use the toolbar for drawing and highlighting
  3. Add text using the text tool
  4. Click "Save" to keep changes

Limitations: Basic editing only - drawing, highlighting, and text notes.

Editing Scanned PDFs

Scanned documents are essentially images, so you can't directly edit the text. To edit scanned PDFs:

  1. Use OCR tool to convert to searchable/editable text
  2. Then use the PDF to Word conversion for text editing
  3. Or use a PDF editor to add new text on top

Tips for Better PDF Editing

1. Work with a Copy

Always edit a copy of your original file. Some changes can't be undone, and it's good to have a backup.

2. Match Fonts

When adding text, try to match the existing font style for a cohesive look. Common PDF fonts include Arial, Times New Roman, and Calibri.

3. Use Layers

When adding content on top of existing text, use white shapes to cover the original text first if needed.

4. Check the Output

After editing, zoom in to verify text alignment and quality. Print preview can also help catch issues.

âš ī¸ Important

Editing PDFs doesn't always produce perfect results. For important documents, consider recreating from the original source if possible.

Specific Edit Tasks

Delete Pages

Use Remove Pages to delete unwanted pages from your PDF.

Rearrange Pages

Use Organize PDF to reorder pages, rotate them, or remove specific pages.

Add Page Numbers

Use Page Numbers to add automatic page numbering to your document.

Crop Pages

Use Crop PDF to adjust page margins and visible area.

Redact Sensitive Info

Use Redact PDF to permanently remove sensitive information.
