The password protection is not copied into the new file
The output is a newly created PDF that does not carry forward the source encryption dictionary. The downloaded copy can therefore be opened without the original document password.
That is the main purpose of the Unlock PDF workflow.
Each source page is rendered before rebuilding
Instead of rewriting the original encrypted PDF objects in place, 1into1 renders each decrypted page at high resolution and embeds the rendered result into a fresh page.
This makes the output visually oriented rather than structurally identical to the encrypted source.
Text selection and interactivity are lost
The rebuilt pages are JPEG-backed images. Native selectable text, OCR text layers, hyperlinks, form fields, annotations and similar interactive structures are not preserved as their original PDF objects.
The visible appearance can remain readable, but the document behaves more like a scanned PDF afterward.
Unlocking is different from changing PDF permissions in place
Adobe distinguishes removing a document-open password from removing permissions restrictions such as editing and printing controls.
The current 1into1 tool does not expose a granular permissions editor. It accepts a password and produces a fresh unencrypted image-based copy.
Choose the workflow based on what you need afterward
Use this Unlock PDF workflow when the priority is obtaining an unencrypted visual copy for authorized viewing, sharing or a downstream process that rejects encrypted files.
If you need to preserve form fields, links, searchable text or original vector objects, use an authorized decryption tool that preserves the original PDF structure instead.
