Tips for editing PDFs online
Zoom in on the area you're editing so new text lines up with the original. Match a common font like Arial or Helvetica and pick a similar size and color so additions blend in. Use the Move tool to reposition anything you've added, double-click text to edit it, and drag the corner handle to resize an image or signature. Editing happens in your browser on your own device, so your changes aren't uploaded to our servers — but avoid uploading highly sensitive files unless you're comfortable using a web-based editor.
