Protected document delivery with copy controls

Choose protection by what happens after delivery

A password can stop an unauthorized person from opening a file. It does not automatically control what an authorized recipient can copy, print, capture, or redistribute after opening it. The right method depends on the file format, recipient environment, and level of post-delivery control required.

Quick answerUse Adobe PDF permissions for a PDF-only job, Microsoft passwords when the main requirement is opening protection, and Microsoft 365 IRM for named users in a managed organization. Use GiliSoft Copy Protect when PDF and Office files must leave your computer as a controlled offline package with copy, print, clipboard, screenshot, password, device, watermark, and expiry rules.

Method 1. Protect delivered documents with GiliSoft Copy Protect

Use this method when customers, students, partners, contractors, or field teams should view documents without receiving ordinary reusable PDF, DOCX, XLSX, or PPTX files. Copy Protect can package Office files, PDFs, WPS documents, images, web pages, supporting media, and mixed folders together.

GCP protected packageUse the GCP format for controlled playback through the GiliSoft reader and for projects that are not suited to a single EXE file.
EXE packageCreate a self-running Windows package for smaller deliveries. EXE output has a 4 GB limit, so use GCP for larger projects.
Viewer permissionsConfigure copy and paste, clipboard, printing, screenshots, Save As behavior, and virtual-machine playback.
Delivery bindingBind access to a PC, USB drive, CD, or DVD and keep separate administrator, client, and demo settings.
  1. Open Copy Protect and add the PDF, Word, Excel, PowerPoint, WPS, image, web, or supporting media files required for delivery.
  2. Choose the output format: GCP for flexible protected delivery or EXE when the package is within the 4 GB limit.
  3. Set the opening password and configure client permissions for copying, printing, clipboard use, screenshots, and related viewing behavior.
  4. Add PC, USB, CD, or DVD binding when the package should open only on approved hardware, then build and test it on a separate Windows PC before distribution.
Add PDF and Office files to GiliSoft Copy Protect
Add individual documents or a complete project folder before selecting the protected output.
Configure document copy and print permissions
Define recipient permissions for copying, printing, screenshots, clipboard use, and related viewing behavior.
Bind protected document packages to approved devices
Bind a protected document package to approved computers or removable media when a shared password is not enough.

Use Copy Protect when documents leave your control

This is the primary GiliSoft recommendation for training manuals, paid reports, sales proposals, price lists, internal procedures, design documents, and client deliverables that should be viewed without distributing editable source files.

Method 2. Restrict PDF printing, editing, and copying in Adobe Acrobat

For a PDF-only delivery, Acrobat can use a document-open password and a separate permissions password. Adobe's permissions settings can control printing quality, editing, page extraction, comments, and whether text or images may be copied.

  1. Open the PDF in Acrobat and select All tools > Protect a PDF.
  2. Select Encrypt with Password, then enable Restrict editing and printing of the document.
  3. Choose the allowed printing level and document changes, and decide whether text and image copying remains enabled.
  4. Set a strong permissions password, save a new copy, and verify the restrictions in a separate reader session.
Use the right password type. A document-open password controls who can view the PDF. A permissions password controls actions such as printing, editing, and copying.

Method 3. Password protect Word, Excel, or PowerPoint files

Office file passwords are appropriate when trusted recipients still need the original editable file. In Word, Excel, and PowerPoint, the desktop application can encrypt the file so it cannot be opened without the password. Some formats also support a separate password to modify the document.

  1. Open the Office file and go to File > Info.
  2. Select Protect Document, Protect Workbook, or Protect Presentation, then choose Encrypt with Password.
  3. Enter and confirm a strong password, save the file, and reopen it to verify access.
Do not confuse opening protection with usage control. Once an authorized recipient opens the original file, ordinary content can still be copied, photographed, or recreated. Keep a secure record of the password because Microsoft may not be able to recover it.

Method 4. Restrict named users with Microsoft 365 IRM

Information Rights Management is relevant when files stay inside a managed Microsoft 365 environment. Supported Office applications can assign Read, Change, or Full Control permissions to named users or groups. Microsoft documents that Read permission can prevent editing, printing, and copying unless the author explicitly allows those actions.

  1. Save the Office file, then open File > Info.
  2. Select the relevant Protect command, then Restrict Permission by People > Restricted Access.
  3. Add approved users, choose their permission level, and configure expiration or print and copy options where available.
  4. Test the file with an actual recipient account before external distribution.
IRM is account-based. Availability depends on the Microsoft 365 tenant, licensing service, supported application, sensitivity-label policy, and administrator configuration.

Method 5. Use read-only controls only for accidental changes

Read-only mode, worksheet protection, Restrict Editing, and Mark as Final can be useful for internal review. They are not substitutes for document encryption or controlled delivery. Microsoft specifically notes that worksheet protection is not a security feature, and a Word editing restriction without a password can be stopped by the recipient.

Word Restrict EditingLimit the document to read-only or selected editing types, then enforce the rule with a password when appropriate.
Excel worksheet protectionPrevent accidental formula or cell changes; do not present it as protection for confidential workbook data.
Mark as FinalSignal that a file is complete and discourage edits, but expect recipients to be able to remove the status.
Protected packageUse Copy Protect when the finished document must leave the organization under viewing and reuse rules.

Add visible identity before external document delivery

A watermark does not stop copying, but it can make ownership, recipient identity, order information, or confidentiality visible on every page. Use document-native watermarks for ordinary files, or configure visible marks in the protected delivery when recipient-level traceability matters.

Recipient identityInclude a customer name, account, email, or order reference when each package is prepared for a specific recipient.
Document purposeUse labels such as Confidential, Review Copy, Internal Training, or Licensed Customer Copy.
PlacementKeep the mark visible without covering formulas, diagrams, signatures, or text required for legitimate use.
TestingInspect representative pages and print previews before sending the final protected package.

Recommended setup for common document scenarios

Paid report or training manualKeep the source files internally, then package the PDF and supporting media with Copy Protect. Apply password, copy, print, screenshot, watermark, and expiry rules.
Proposal or price list sent to a clientDeliver a controlled package when the recipient only needs to review it. Send the editable Office source only when collaboration is required.
Documents inside Microsoft 365Use IRM when every viewer has an approved organizational account and the tenant supports rights management.
Source files stored on your own PCUse File Lock Pro to lock, hide, or protect local source documents and project folders before delivery.

Document copy protection FAQ

Can document copy protection stop every possible copy?

No software can prevent a viewer from photographing visible content or manually recreating it. The practical goal is to stop ordinary file redistribution and restrict common reuse paths such as copy, paste, print, screenshots, Save As, and opening on unapproved devices.

Can GiliSoft protect PDF and Office files together?

Yes. A protected project can include PDF, Word, Excel, PowerPoint, WPS, images, web pages, media, and supporting folders. This is useful when a delivery contains more than one document format.

Should I use File Lock Pro or Copy Protect?

Use File Lock Pro to protect source documents stored on your own Windows PC, external disk, or shared folder. Use Copy Protect when documents must be delivered to another person under controlled viewing rules.

Should I choose GCP or EXE output?

Use GCP for the standard protected reader experience and larger projects. Use EXE for a self-running Windows package when the delivery is within the 4 GB EXE output limit.

Deliver protected documents instead of reusable source files

Create a GCP or EXE package for PDF, Office, WPS, images, and supporting files, then configure how recipients can open, copy, print, capture, and reuse the content.
