Fine-tune the four corners by hand, rotate, then pick a filter: Original, Magic Color, Grayscale or Black & White. Brightness and contrast sliders for the difficult pages. SIGN AND ANNOTATE Draw your signature once and reuse it forever. Drop it on any page, then drag and resize it exactly where it belongs. Or annotate freehand in three colors and three widths. TEXT RECOGNITION Pull the text out of any page with on-device OCR - copy it, share it, or search your whole library by the words inside your scans. EXPORT THE WAY YOU NEED - Multi-page PDF - One JPEG per page - A single stitched long image - Plain text file Choose paper size and quality, add page numbers, a diagonal watermark, or a password to protect the PDF.
