PDFCrab lets you edit PDF files directly on your iPhone โ€” no cloud, no subscriptions, no sign-in required. All processing happens locally on your device. -Forms Fill interactive PDF form fields directly in the app, then export the completed form. -Search in your PDF Search for any word or phrase across your document and replace it in place โ€” the surrounding text keeps its layout. -Highlight text Highlight any passage of text to make it stand out. Choose the highlight color and opacity, then move or remove a highlight at any time. -Smarter text editing Related text now groups into sections, so you can select and edit a whole block at once instead of line by line. -OCR Scan a photo or PDF of a document and PDFCrab recognizes the text on-device, turning it into real, selectable, editable PDF text instead of a flat image. Review and correct recognized text, then save as separate files or merged into one PDF. -Cyrillic, Chinese, Japanese & Korean support Editing text and recognizing text via OCR now correctly handles Cyrillic and CJK scripts, not just Latin โ€” the right font is embedded automatically based on what the text actually contains. -Edit text Tap any text in your PDF to select it, then drag it to a new position or update its content. Choose from 9 bundled fonts or keep the original. Preview font and size live before saving. -Edit images Move, resize, or remove images embedded in your PDF. Drag any corner or edge handle to resize precisely, or pick a quick percentage preset. -Page Tools Add page numbers in the position you choose, rotate any page, and switch between Standard and Letter page sizes โ€” with a one-tap way back to the original size. -Manage Pages Browse a thumbnail grid of all pages to delete the ones you don't need โ€” now extended with Reorder: drag pages into a new order and save when you're ready. -Export Turn any PDF into a TXT file, an audio narration, page images, a Word document, or a PowerPoint โ€” directly on your device. -Password-protected PDFs Open, edit, and save encrypted PDFs. Add, remove, or change passwords. View encryption algorithm, key length, and per-flag permissions. Your password never leaves your device. -Annotate Draw, highlight, and add freehand annotations using Apple Pencil or your finger. -Privacy first PDFCrab never uploads your files. Everything stays on your device.
