What can I do with Edit PDF?

Three modes: Forms (draw fillable boxes or fill existing fields), Markup (text, images, rectangles, lines, signature), and Blackout to cover private information.

Can others type into fillable boxes after download?

Yes. Boxes are saved as real PDF form fields in Preview, Acrobat, Chrome, and similar apps.

Blackout flattens covered areas into page images so recipients cannot simply delete a black shape to reveal text. Suitable for everyday sharing, not forensic-grade redaction.

Can I move or resize items after placing them?

Yes until you download. Select an item to drag, use corner handles to resize, or press Delete/Backspace to remove it.

Does editing upload my file?

No. Forms, markup, blackout, and download all run in your browser.

Why did Chinese or special characters look wrong when I stamped text?

Standard PDF stamp fonts cover Western characters best. For complex scripts, type into a fillable box (recipients use their system fonts) or edit in Word after PDF to Word.

How to use Forms, Markup, and Blackout safely

Edit PDF covers three jobs: Forms (type into existing fields or draw fillable boxes), Markup (notes, shapes, signatures), and Blackout (cover sensitive text so it cannot be selected underneath). Use the lightest mode that solves your task.

Steps

Open Forms to fill existing fields or draw a fillable box for others to type into.
Use Markup for comments, rectangles, images, and signatures.
Switch to Blackout only for private data — blackout flattens those areas.
Download once you are done; review the file in another reader before sending.

When to use it

School or workplace forms that arrive as PDF
Marking up a contract draft with notes (not legal e-sign unless required)
Sharing a document after hiding ID numbers or addresses

Tips

Fillable boxes stay editable for recipients in common PDF apps.
Blackout is for everyday privacy, not forensic-grade scrubbing.
Do not hide private text with a Markup rectangle — use Blackout.
