Frequently Asked Questions

How does editing existing PDF text work?

The editor uses client-side text item detection to identify text coordinates. When you click and edit a word or number, it cleanly whites out the old text and draws your replacement text in its exact position.

Is there any subscription fee or download limit?

No. MultiToolX PDF Editor is 100% free with unlimited edits, zero paywalls, and zero watermarks.

Do my uploaded documents stay private?

Yes. All rendering, editing, and PDF reconstruction happens locally in your browser memory. Your files never touch an external server.
