PDFKit is a PDF reader and a full PDF toolbox in one app. Every tool works on your iPhone and iPad: your files are processed on the device, never uploaded to a server, and every result is saved as a new file, so your original stays as it was. All of it works offline, with no watermark on your files. PDF TOOLS β’ Merge: join PDFs into one file, in the order you choose β’ Split: by page ranges, every page, or every few pages β’ Extract pages: copy the pages you pick into a new PDF β’ Organize pages: drag thumbnails to reorder, delete pages (with undo) β’ Rotate pages: turn some or all pages β’ Compress: re-encodes photos and scans at the level you choose and shows the real size before and after. If a file canβt get smaller, PDFKit says so instead of saving a bigger copy β’ Images to PDF: photos, image files or the camera; reorder, crop and rotate; A4, Letter or the photoβs own size β’ Scan to PDF: take a photo of each page, crop and rotate as you go β’ PDF to images: every page as JPG or PNG at 150 or 300 dpi β’ Sign: draw your signature once, keep it on this device, place and resize it on any page β’ Watermark: your text across every page, with colour, opacity, angle and size β’ Page numbers: six positions, four formats, start number, skip the cover β’ Add password: AES-256 encryption with a password you choose β’ Remove password: with the password, save a copy that opens without one Results show their name, pages and size, with Open, Share, Save to device and Use in another tool.
