Frequently Asked Questions

Can I edit existing text in the PDF directly?

Because PDF stores static positioned glyphs rather than reflowable paragraphs, you can use our PDF Text Eraser to redact original text, and then use Edit PDF to place new text in its exact position.

Are my annotations permanent in the exported document?

Yes. FileTools writes vector operators directly into standard PDF content streams, ensuring annotations appear identically across all PDF readers.

Can I sign PDF documents with this editor?

Yes. The built-in Signature tool lets you draw your signature using a mouse, trackpad, or touchscreen and stamp it anywhere on the document.

Can I add text notes and annotations to an existing PDF without Adobe Acrobat?

Yes. FileTools allows you to add text boxes, draw freehand annotations, highlight passages, and insert shapes directly in your web browser.

Does editing an existing PDF alter the underlying vector fonts?

Existing vector text remains intact, and your new text and drawing elements are overlaid as clean PDF vector and text annotation streams.

Can I white-out sensitive information or highlight text with this editor?

Yes. You can use the rectangle tool to cover sections, apply colored highlighter boxes over key phrases, or insert freehand pencil marks.
