## What is Easy Secure PDF?

Photograph a document, straighten it, lock it with a password.
That is all this app does.

Contracts, payslips, medical notes, copies of an ID.
It is a tool for the documents you need to send but would rather not
send unprotected.

■ A photo becomes a PDF
Photograph the document, or pick one from Photos. That is the whole step.
Shot at an angle? The four corners of the paper are found automatically
and the page is straightened into a rectangle.
If the corners are not found, or they are slightly off, drag them into
place with your finger.

■ Any number of pages, one PDF
Two pages, three, more. Every photo you take goes into the same PDF.

■ Lock it with a password (free)
You can put a password on the PDF.
Whoever receives it cannot open the contents without typing that password.
Tell them the password some other way than the PDF itself.
Writing it in the same email defeats the point.

■ Make it easier to read (paid)
"Adjust" gives you sliders for brightness, contrast and colour,
and the preview changes as you drag.
"Black & white" gives you the clean white page of a desktop scanner and
sharpens the text. It helps with faint pencil, receipts and thin print.

■ Reorder pages (paid)
Photographed them out of order? Move them afterwards.
(Adding and deleting pages needs no purchase.)

■ Add a watermark (paid)
Words such as CONFIDENTIAL are laid diagonally across the whole page,
so cropping a corner will not remove them.

■ Shrink it for email (paid)
Pick one of five sizes. Each choice shows the measured size per page,
and the preview is drawn at that resolution, so you can check it is
still readable before you send it.

■ Your documents stay on your device
The documents you photograph and the PDFs you build never leave your
device. Nothing is sent to a server and nothing is stored in a cloud.
(The only network use is for ads and the one-time purchase.)
These are documents you would not show to a stranger, so the app is
built not to have that option in the first place.

■ Your original photos are untouched
Only the contents of the PDF are processed.
The photos in your Photos library are never modified.

■ Works on iPhone and iPad
