What does PDF Permissions do?

It creates a restricted copy of your PDF where text can’t be copied, forms can’t be filled, and annotations are removed. It works by converting pages to images, so the restrictions are structural.

Is my PDF uploaded to a server?

No. The tool rasterizes and rebuilds the PDF entirely in your browser. Nothing leaves your device.

How is this different from setting permission flags?

Standard PDF permission flags are metadata that readers can choose to ignore. OxygenPDF rasterizes the pages into images. There’s literally no text layer to copy from and no form fields to interact with.

Will the document look different?

Pages are rendered at 2x resolution with 92% JPEG quality. For most documents the visual difference is negligible. Text-heavy documents may show slight compression artifacts at high zoom.

Will the file size change?

It depends on the original content. Image-heavy PDFs may get smaller. Text-heavy PDFs may get larger since text is converted to images. The tradeoff is genuine restriction enforcement.

Does it work with password-protected PDFs?

Yes. Enter the password to decrypt, then apply permissions. All processing runs locally.

About PDF Permissions

How PDF Permissions Work

Standard PDF permission flags are easy to bypass — most PDF readers ignore them. OxygenPDF takes a different approach: it rasterizes each page into a high-quality image and rebuilds the PDF from those images. There’s no text to copy, no form to fill, no annotation layer to edit. The restrictions are structural, not flags.

You pick which restrictions to apply: disable text copying, remove form fillability, strip annotations. The tool renders every page at 2x resolution and reassembles them into a new PDF at 92% JPEG quality. The visual result is nearly identical to the original.

When to Restrict PDF Permissions

Sharing a document is not the same as giving permission to reuse it. Restrictions set boundaries.

Prevent Text Copying

Reports, research, and proposals you share for reading — not for someone to copy-paste into their own work.

Lock Down Forms

Distribute completed forms that can’t be tampered with. Remove fillability so the submitted data stays fixed.

Strip Annotations

Remove comments, highlights, and markup before distributing a final version. Keeps the document clean.

Protect Published Content

Whitepapers, case studies, and marketing PDFs that should be read, not disassembled.

How It Compares

Most PDF tools set permission flags in the file header. Readers can ignore those flags. Rasterization enforces restrictions at the content level.

Processing Stays on Your Device

Documents that need permissions restrictions are usually documents with sensitive content. Uploading them to apply permission flags that anyone can bypass isn’t much of a security story.

OxygenPDF rasterizes and rebuilds the PDF in your browser. The original file stays on your device. The restricted version is generated locally and downloads straight to your machine.
