The documents you were told not to upload.

Black something out so it stays blacked out

You choose what to cover. Then it takes a photograph of each page and throws the original page away. What you are left with is a picture of the page with black boxes painted on top, and there is nothing underneath the boxes because there is no underneath any more.

You can draw the boxes yourself, or type a name or a number and it finds every place it appears. It shows you each one before it covers anything.

Before it hands the document back, it opens it again and checks its own work. If anything is wrong it refuses to give you the file and tells you what went wrong.

What it costs youThe finished page is a picture, so you can no longer search it for a word, and software that reads pages aloud will not be able to read it. That is the price of doing it properly, and it is the reason it works.

Make a document small enough to email

Sometimes a document is too big to attach. This makes it smaller and tells you which of two ways it used.

One way keeps the words as words, so you can still search the document. The other turns the pages into pictures, which makes it much smaller and works best on documents that are mostly photographs.

If making it smaller would actually make it bigger, it says so and gives you nothing, instead of handing you something worse with the word “compressed” on it.

What it will not doVery large documents can be too much for the browser to hold. If that happens it stops. Nothing is lost, because your original is never touched.

Turn iPhone photographs into ordinary pictures

iPhones save photographs in a form many computers and websites cannot open. This turns them into the ordinary kind that everything can open, a whole batch at a time.

It can also take out the record of where each photograph was taken. That record is stored inside the picture itself, and most people do not know it is there.

What it will not doPhotographs that move when you press them come out as the still picture only. A few unusual ones cannot be read, and it tells you which rather than skipping them quietly.
