PDF Maker transforms your iPhone into a portable document studio. Whether you need to convert photos to PDF, merge contracts, compress large files, or scan receipts on the go - everything happens in seconds, right in your pocket. CONVERT PHOTOS TO PDF Turn any image into a professional PDF document. Select photos from your library, snap pictures with your camera, or import files. Adjust quality settings from draft to maximum resolution. Choose page formats including A4, Letter, Legal, or let the app fit pages to your images automatically. Perfect for digitizing old photographs, creating photo albums, or preparing image-based reports. DOCUMENT SCANNER Your phone camera becomes a powerful scanner. Capture documents, receipts, whiteboards, and handwritten notes with automatic edge detection. The built-in scanner recognizes document boundaries and optimizes contrast for crystal-clear results. No more hunting for a scanner - handle paperwork anywhere, anytime. MERGE MULTIPLE PDFs Combine separate PDF files into one organized document. Drag to reorder pages exactly how you want them. Great for assembling project documentation, combining invoices for expense reports, or creating comprehensive portfolios from multiple sources. COMPRESS & REDUCE SIZE Large PDF files slow everything down - email attachments bounce back, cloud storage fills up, sharing becomes frustrating. Our compression engine shrinks file sizes significantly while preserving readable quality. Send documents faster and save storage space without sacrificing clarity. FLATTEN PDF DOCUMENTS Working with forms that have fillable fields? Need to lock down annotations and comments? Flatten converts interactive elements into static content. This prevents further editing and ensures your document looks identical on every device and printer. ROTATE PAGES Fix upside-down scans or sideways photos instantly. Rotate individual pages or entire documents in 90-degree increments. Preview changes before saving. Simple controls make orientation corrections effortless. VIEW & EDIT Browse your PDFs with smooth scrolling and sharp rendering. Select specific pages to rotate, delete, or extract into new documents. Thumbnail view helps you navigate long files quickly. Edit tools give you control over document structure without needing desktop software. INTUITIVE DESIGN Dark interface reduces eye strain during extended use.
