PDFCrab lets you edit PDF files directly on your iPhone β€” 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 β€” 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 β€” 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 β€” 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 β€” 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 β€” 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.

About

SpeechToMarkdown

Read full description

Turn your voice into clean, structured Markdown β€” entirely on your iPhone or iPad, with zero setup and zero cloud. Speech-to-Markdown listens as you talk and turns your rambling into a well-organized document in real time. Speech-to-text runs on Apple's on-device SpeechAnalyzer; formatting is handled by Apple's on-device Foundation Models. No servers, no API keys, no sign-in β€” it even works in airplane mode. HOW IT WORKS Just start a session and talk. As you speak, your words stream into a live document that gets restructured on the fly β€” headings, lists, and paragraphs appear as you go. Pause, resume, or start a new session anytime; everything is saved automatically and stays on your device. THREE WAYS TO USE YOUR VOICE β€’ Format β€” free-form dictation. Ramble, and the whole document keeps getting reorganized as you add more. β€’ Edit β€” turn your voice into an instruction. Select some text, then say "turn this into a bulleted list" or "rewrite the intro" and only that part changes. β€’ Append β€” a fast mode for long documents. Only your new words get formatted and added to the end, so sessions stay quick no matter how long the document grows. THREE OUTPUT FORMATS Choose Markdown, plain text, or HTML β€” pick per session, switch anytime. BUILT FOR PRIVACY Everything happens on-device. There's no account to create, no analytics, no ads, and nothing is ever uploaded anywhere. Your recordings and documents live in the app's local storage and are visible in the Files app, under your control. SESSION HISTORY Every session is saved automatically. Reopen any past session to keep talking, edit the document, or export it β€” your raw transcript is always one tap away from the formatted result. GREAT FOR Meeting notes, journaling, blog and spec drafts, to-do lists, brainstorms, voice memos you actually want to read later β€” anywhere you'd rather talk than type. REQUIREMENTS iOS 26 or later on an Apple Intelligence–capable device: iPhone 15 Pro or newer, or an Apple Silicon iPad, with Apple Intelligence enabled in Settings.
