Saving
Two files. Pick the one the next reader needs.
Normal Save
A standard PDF. Highlights, notes, and drawings stay in the file. Preview, Acrobat, and email can open it.
Save With Password
Encrypted on your computer before it is written to disk. Secure PDF Viewer asks for that password the next time the file is opened. Another PDF app is not expected to show the protected document.
The password never leaves the computer. We cannot reset it. If it is lost, that protected copy cannot be opened.
01
Move through the document.
Open a file from the toolbar, or drop it on the window. Each PDF keeps its own tab. Use the outline, the thumbnails, zoom, and search to get to the page you need.
- Page navigation, zoom, and search
- Document outline and thumbnails
- A tab for every open PDF
- Print from the toolbar
02
Mark the page. Keep the original text.
Highlight a passage, write a note, or draw on the page. Save, and those marks stay in the file. This is markup on top of the page. It does not rewrite the PDF’s original wording.
- Highlights in different colors
- Text notes with color and size
- Drawing and other page markup
- Annotations stored when you save
03
Two ways to save.
Normal Save writes a standard PDF, annotations included, that other readers can open. Save With Password encrypts the document on your computer. Secure PDF Viewer asks for that password the next time you open the file.
- The password is used only on your computer
- It is not sent to us, and we cannot recover it
- Open the protected file again in this app
- Use Normal Save when another app needs the file
A session
From a file on disk to a file you can send.
- 01
Open
Drop a PDF on the window, or use Open. Each document keeps its own tab, so a long report and a one-page form can stay open together.
- 02
Find the page
Use the outline, thumbnails, search, and zoom. Rotate a page, change the scroll, or switch between single pages and spreads.
- 03
Mark it
Highlight a passage, leave a text note, or draw on the page. The marks sit on top of the document. They do not rewrite the original wording.
- 04
Save the right copy
Normal Save is a standard PDF for anyone. Save With Password is the copy you intend to open again in Secure PDF Viewer.
How it is built
A local app, with a clear limit.
No account
There is no sign-in and no cloud library. The app starts, you open a file, and the work stays on that computer.
No document upload
Reading, markup, and encryption happen on the machine. The PDF is not sent to us so we can process it.
Password stays with you
Save With Password uses the password you type on that computer. We never receive it, and there is no reset.
Markup, not a rewrite
Highlights, notes, and drawings are annotations. Secure PDF Viewer does not edit the existing body text of the PDF.
The rest of the window.
Thumbnails, notes, the password prompt, and the page tools.
Also on the toolbar.
