Let the Text Boxes Do the Talking

In the app, you can also easily add customizable text boxes with your comments. Move them around the page, and change the fonts, color, and spacing. Combine them with shapes or highlighting for clarity. 

Moreover, in iScanner, you can add a new page to the document with one tap. This can come in handy when there’s a lot to say and a text box won’t do the trick.

Annotate Like a Pro with Watermarks

Watermarks are a neat way of providing some crucial information about a document without interfering with the original content. You can use it to: 

  • Indicate the status of a document (e.g. draft, obsolete, version number, etc.)
  • Provide additional information (like strictly confidential)
  • Give instructions
  • Facilitate document reviews

In iScanner, you can apply customizable watermarks in a tap. 

  • Upload your file (text document or image) to iScanner and tap the Watermark icon at the bottom right. 
  • Type the text you want to use in the text box. 
  • Choose the font, size, color, transparency, and spacing of the text. The app allows you to see the changes in real time.

Moreover, you can edit or delete the watermark at any point even after saving the changes.  

All in all, annotation on a mobile device can help you make better use of your time, help you stay organized on the go, and make communication more efficient.  Don’t hesitate to take advantage of a nifty tool like this to boost your productivity!
