Step-by-Step Guide

Open the Edit PDF or Annotate PDF tool on PDFLoves.me.

Upload your PDF — Drag and drop or click to browse.

Select a tool — Choose from Text, Pen, Highlight, Rectangle, Arrow, or Redact in the toolbar.

Customize — Pick a color, adjust font size or line width.

Draw or click on the page — Your annotation appears instantly on the canvas.

Use Undo/Redo — Made a mistake? Click the undo button or redo to restore.

Navigate pages — Use the page arrows to annotate different pages.

Delete individual items — Each annotation appears in a list below the canvas with a delete button.

Click "Save & Download" — All annotations are permanently embedded into the PDF.

Redacting Sensitive Content

The Redact tool lets you permanently hide text, images, or any visible content:

Switch to Redact / Hide mode.

Choose black or white as the cover color.

Click and drag over the area you want to hide.

The area is covered with an opaque rectangle.

When you save, the rectangle is permanently embedded — the hidden content cannot be recovered.

This is the same approach used by professional tools like Adobe Acrobat for client-side redaction.

Tips for Better Annotations

Use Highlight for marking important passages in contracts or study materials.

Use Arrow + Text together to create callout annotations.

Use Redact to hide personal information before sharing documents.

All tools support 5 colors — black, red, blue, green, and orange.

Frequently Asked Questions

Can I edit existing text in the PDF?

The tool adds content on top of the existing PDF. To hide existing text, use the Redact tool to cover it with an opaque box.

Are the annotations permanent?

Yes — once saved and downloaded, all annotations are embedded in the PDF file. Use Flatten PDF to make them completely non-removable.

Is there an undo feature?

Yes — full undo and redo support. Every add or delete action can be undone and redone.

What is the difference between Edit PDF and Annotate PDF?

They are the same tool. "Annotate PDF" is an alternative name targeting users searching for annotation-specific features.
