sign pro PDF v3.6.17
Wacom Co, Ltd.About this app
Developer Description
The complete solution for signing and annotating PDF documents.
When you use sign pro PDF as your document reader you will also have tools for:
- Electronic handwritten signatures
- Freehand annotations
- Sticky note texts
- Text highlight, underline and strikethrough
PDF files that require signatures or annotations may be transferred to a device through various means. For example, you might receive an email with a PDF file attachment which requires your signature. You can open the file attachment and view its contents directly in sign pro PDF. To sign the document, you can select the signature tool, select a position in the document and then sign using your finger, capacitive stylus or Wacom active stylus. You can then send your email reply with the signed PDF document attached.
Your signed document can be viewed in any PDF reader and your signature will appear exactly as you created it. In addition, sign pro PDF follows industry-standard PDF electronic signature standards so any changes to the document will result in signatures being shown as invalid.
The stylus used to sign determines the type of signature created:
- ‘touch’ signatures created using your finger or capacitive stylus do not contain biometric data
- ‘biometric’ signatures created using a Wacom active stylus contain full biometric data including pen pressure

How I can change a language of interface and text in app?
Tried to fill in a scanned form with the annotation feature using a samsung galaxy note stylus. 1. The lack of palm rejection makes it difficult to use. 2. Handwriting ink is obviously lagging after a few fields. 3. Some ink made accidentally by the palm couldn't be erased. 4. Going to the annotation mode, i cannot zoom in/out with my fingers. Need to exit annotation mode, zoom, go back into annotation mode, to continue annotating.
It requires a new signature each time you sign. No signature library.
