How protection works

Each page is rendered as a high-quality image and re-embedded into a new PDF. This prevents text selection, copying, and editing — making your document read-only. The original formatting is preserved visually.

Frequently Asked Questions

How does the protection work?▼
Each page is rendered as a high-quality JPEG image and embedded into a new PDF. This makes the text non-selectable and non-copyable — effectively making the document read-only.
Does this add AES encryption?▼
This tool provides practical protection by flattening text into images. For military-grade AES-256 encryption, dedicated desktop software is recommended.
Can the protection be reversed?▼
Since pages are rasterized into images, the original selectable text cannot be recovered from the protected version. Always keep a backup of your original document.
