PDF Studio - PDF Editor

Scan, edit, fill and sign PDFs on your iPhone and iPad with PDF Studio. Completely free, with no ads, subscriptions or account requirement.

SCAN AND CREATE
• Scan multi-page documents with the camera or create a PDF from photos.
• Review pages before saving: rotate, delete and reorder them.
• Adjust four corners for perspective correction and choose grayscale, black-and-white or clean scan modes.
• Import PDFs from Files, Mail and other apps.

EDIT, FILL AND SIGN
• Merge, split and reorder pages, or insert a blank page.

• Place text, dates and checkmarks exactly where needed on forms without editable fields.
• Draw a black or blue signature, drag and resize it on the page, and save it for reuse.
• Edit existing text annotations and selected paragraphs. Original styling is preserved where possible; exact layout preservation depends on the PDF.

• Add watermarks and page numbers, and edit document properties.
