About five rows around the pointer fade to ~1% opacity. The rest of the page remains under the mesh.
A moving mesh over your PDF. Only the reader's cursor clears it.
Fence View paints a full-screen mesh of text characters on top of the PDF viewer. A narrow band of rows around the reader's cursor, or finger on mobile, fades to near-zero opacity so it can be read. Everywhere else stays covered.
The goal is not to stop reading. It is to break the shape of a screenshot: a full-page capture returns mostly mesh, because only a few rows were ever clear at the moment the shutter fired.
Each row is a real element with its own opacity toggle. That is why screenshots do capture the mesh as drawn.
A single screenshot or screen recording frame shows one clear strip and a lot of mesh. That is the point.
At any instant, most of the page is covered. A full-page grab is mostly mesh plus one thin readable band.
Must track cursor to reveal lines one at a time. Slower, more tiring than normal reading. Protects against casual screenshots at the cost of friction.
A curtain of vertical bars, with a small clear window that follows your cursor.
Fence View is a simple idea. Once you picture the curtain and the moving clear window, the rest follows.
A curtain is drawn over the PDF
When the page opens, MaiPDF lays a dense pattern of vertical bars across the whole reading area. The PDF sits underneath, hidden behind the pattern.
The pattern fills every line
The bars run edge to edge, top to bottom, as a solid visual texture. From across the room it looks like a striped blind covering the page.
Where you point, a narrow band clears
As your mouse or finger moves across the page, a short strip of the curtain right under the pointer fades away, so you can read the few lines you are looking at.
Move away and the curtain closes
The moment the pointer leaves, the bars slide back in over those lines. The clear band is always small, and always only there while you are actively reading it.
Zoom, resize, rotate, still covered
If you change the window size on a laptop or turn your phone sideways, the curtain is automatically redrawn to match the new shape. No gaps are left uncovered.
Right-click and copy are turned off
Right-click "Save Image As" and text selection copy are both switched off in the viewer, so no one can sneak past the curtain by pulling the page out a different way.
Move your cursor across the box.
This is a simplified demo, not the real reading view. It shows the idea: only the rows under the pointer clear, the rest stays covered.
Four steps to share a PDF in Fence View.
Fence View is a reading-mode choice inside the normal MaiPDF share flow. There is no separate product or extra install.
Upload the PDF
Start in the MaiPDF upload page. No login needed to try; logged-in users can manage the share later.
Pick Fence View mode
In the sharing settings, choose Fence View instead of the default reading mode. Add expiration, access limit, and watermark.
Generate link or QR
The same share flow returns a URL, QR code, Read Code, and Modify Code. Distribute the link however you share normal PDFs.
Check access records
After the link is opened, review who accessed it. Fence View does not replace this trail, it sits alongside it.
Good pairings with Fence View
- Dynamic watermark: any screenshot that does get through carries the reader's identity.
- No print & no download: keeps the PDF inside the governed viewer rather than escaping as a raw file.
- Access limit & expiration: shrinks the window an attacker has to iterate.
- Email verification: ties each open to a known recipient before the mesh even loads.
Two reading modes, different trade-offs.
SecureView is the everyday default. Fence View is the stricter option for documents where a clean full-page screenshot is the real risk.
SecureView
Protected reading without the overlay.
- PDF renders clearly, page by page, in the viewer.
- Download and print buttons are hidden; right-click is disabled.
- Best when reading comfort matters more than screenshot friction.
- Good default for client decks, shared reports, course readings.
Fence View Stricter
Everything SecureView does, plus the moving mesh. Reading is noticeably slower.
- A pipe-character mesh covers the whole viewer at all times.
- Only ~5 rows around the cursor clear while the reader looks there.
- Full-page screenshots and screen recording capture mostly mesh.
- Use only when full-page screenshot risk is real, and you accept the friction.
What Fence View is, and is not.
Writing this honestly matters more than a sales claim. Fence View is a friction tool, not a DRM system.
What it helps with
- Full-screen screenshots captured while the mesh is up.
- Screen recording: each frame is mostly mesh plus a narrow clear band.
- Casual right-click, drag-to-save, and text selection copy.
- Signaling that the document is under stricter rules, not casual share.
What it does not claim
- Blocking an external camera pointed at the monitor.
- Blocking patient, row-by-row capture with post-processing.
- Replacing watermarking, access limits, expiration, or records.
- Working when the reader has already downloaded the file locally.
Fence View makes reading slower. Accept that first.
Before you turn this on, know what you are asking your reader to do.
What reading feels like
You move your cursor line by line through the document. Each line is revealed only while you point at it. Looking ahead requires moving your finger or cursor further down. Long documents feel exhausting.
- Scrolling a page takes longer; you guide the reveal band instead of scanning freely.
- Skimming is hard; you cannot see multiple lines at once to jump around.
- Mobile is slower; single-finger tracking on a small screen is tiring.
- Reading comprehension drops when context shrinks to five lines at a time.
This is the price of friction
The mesh protects against casual screenshots because it makes the document harder to read. That is the whole point. If your reader tells you it was painful, they are right.
- Do not use Fence View for long documents unless the content leak is your only concern.
- Do not use it for contracts or materials people need to study carefully; SecureView is better.
- Do not use it for everyday sharing; it is a last resort.
- The reader is doing you a favor by tolerating the friction. Acknowledge that.
The stack Fence View belongs to.
Fence View is most useful when it sits next to watermark, access rules, and records, not alone.
Questions that actually come up.
Direct answers, written the way an operator setting up a real share would ask them.
What does Fence View actually do to a PDF?
How is Fence View different from SecureView?
Does Fence View work on mobile?
Can Fence View stop every possible capture?
Does copy-paste or right-click still work?
When should I pick Fence View over SecureView?
Turn it on for one real PDF and see what a screenshot captures.
Upload a PDF, pick Fence View in the share settings, open the link yourself, and try to take a full-page screenshot. The result is the fastest way to understand exactly what the feature does.
