Edit the real text and images inside any PDF, mark up with 20+ annotation tools, run 43 one-tap actions, sign, OCR, and lock files with AES-256 — all 100% on-device on iPhone & iPad.
No account · No cloud upload · Your documents never leave your device
Most apps do one thing. Kiwi PDF does the whole workflow — from a quick highlight to genuinely rewriting the text baked inside your document.
A task-oriented workshop: merge, split, compress, convert, watermark, rotate, crop, page-number and more — each a simple pick → set → done flow that never touches your original.
Organize · Convert · Edit · Sign · Secure · OptimizeDraw with a smooth pen, highlighter and brush; drop shapes, arrows, clouds, stamps, stickers and sticky notes; add images, links, voice memos and file attachments — 20+ editable tools.
20+ annotation typesGo beyond overlays. Rewrite the actual words in a paragraph, swap or delete embedded images, and turn scans into editable text with on-device OCR — the real content, not a sticker on top.
Edit text · images · OCRA calm reader with Light, Sepia and Dark modes, full-text search across pages and annotations, an editable table of contents, a visual page manager and a full file library.
Reader · Search · Page ManagerLock PDFs with AES password protection, wrap files in AES-256 encrypted ZIPs, redact permanently and flatten for sharing. Nothing is uploaded; no account is ever required.
Password · Encrypted ZIP · RedactYour annotations are saved as standard PDF markup that Acrobat, Preview and any reader can open — never trapped in a proprietary format. Export flattened or fully editable.
Native PDF interopEvery tool runs fully on-device and always leaves your original file untouched. Tap a category to filter.
Everything you add is fully editable — recolor it, change thickness, opacity, borders, fill patterns or fonts, rotate it, and erase it precisely. It all saves as standard PDF annotations any reader can open.
Comment, idea, warning, star and more — plus Approved / Draft / Confidential stamps in four styles.
Reactions, grades, arrows, awards, hands and more — browse by category and place anywhere.
Every drag or slider tweak is a single undo step, and changes auto-save as you go.
Most PDF apps only stick a note on top of the page. Kiwi PDF rewrites the actual text and images baked into the document — old text is truly deleted, and new text stays selectable and searchable everywhere.

← Drag to compare · the words themselves are rewritten inside the PDF →
Tap any paragraph and rewrite the words already printed in the PDF. A real font subset — Vietnamese included — is re-embedded with a proper Unicode map, so the result is copyable and searchable in any viewer. Bold, color and size are preserved.
Every real picture in the page gets a tappable outline — replace it with a new photo, delete it, or drag to move and resize it, right where it sits. It changes the image actually embedded in the file, not a copy pasted on top.
Even on a scanned page where text is just pixels, on-device Apple Vision recognizes the words and lets you edit them like normal text — the old marks are covered with a matching background and replaced with crisp, searchable text.
No third-party or commercial engine — it all runs on-device, writes are append-only, and every change is a single undo step.
A distraction-free reader paired with a full document-management suite — try the reading modes on the left.
Adjustable brightness, three scroll modes and smooth zoom for comfortable long reads.
Search every page and even the text inside your annotations, with highlighted snippets and a thumbnail view.
Jump through long PDFs — and add, reorder, nest or rename outline entries yourself.
Reorder, rotate, duplicate, extract, delete and add pages in one thumbnail grid.
Browse, rename, sort and share your library, inspect detailed file info, and Zip/Unzip with a password.
Everything happens on your device — no uploads, no tracking — while still letting you lock files down with real encryption and share them anywhere.
Lock PDFs with AES encryption using user & owner passwords. Lock or unlock straight from the file manager.
Compress files or whole folders into a password-protected archive, with four compression levels.
Permanently black out sensitive areas and flatten annotations so they can't be moved or removed.
No account, no document ever leaves your device. All processing happens locally, always.
Kiwi PDF shares one feature set across mobile, desktop and the browser — and your annotations round-trip across all of them.
