PHOTO TOOLS

• AI Upscaler: enlarge blurry photos 4× with sharper detail.
• Screenshot Stitcher: merge a run of screenshots into one long image.
• Photo Layout: remove the background, pick a plain backdrop, and arrange prints on one sheet.
• Watermark Camera: stamp photos with time, coordinates, and a note.
SIGN & EDIT
• Handwritten signature: sign with your finger or Apple Pencil, drag it anywhere on the page.
• Page numbers: three positions, three formats.
• Watermark: translucent text laid diagonally across every page.
• Merge, extract, delete, reorder, and rotate pages. Every step can be undone.
EXPORT & SHARE
• Export a copy, or a compressed image-based copy (up to 78% smaller in our tests).
• Split & Export: one file every N pages, saved to a folder in batch.
• Encrypt & Export: set an open password for your PDF.
• Share instantly via the system share sheet.
ENCRYPTED PDFS
