PDFCrab vs CharisPDF

PDFCrab lets you edit PDF files directly on your iPhone — 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 — 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 — 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 — 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 — 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 — directly on your device. -Password-protected PDFs Open, edit, and save encrypted PDFs.

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.

CharisPDF doesn't touch the original content. Everything you add sits on top as its own object, so it stays clean, selectable, and reversible. YOUR PRIVACY, BUILT IN The developer has no access to your files. Nothing is uploaded, tracked, or sold. You accept a short privacy statement once, and that's the entire "account" CharisPDF ever asks for. Charis is Greek for grace — the idea behind this app: put your mark on the document you have, and leave the rest alone.
