AutoAlign vs PersCrop

Straighten leaning buildings in one tap, keep your HDR, and now keep your documents too. Shoot a building from street level and a wide-angle lens makes the walls lean inward. AutoAlign works out the exact angle the photo was taken at and reverses it, so verticals stand straight without the stretched look other tools leave behind. No tripod, no tilt-shift lens. NEW IN 4.0 • Documents: scan receipts, letters, cards and slides, one shot per page. Pages are cropped, straightened and filed by type. • Ask Documents (experimental): ask about your documents with the on-device model of Apple Intelligence. • A new editor in the style of Photos, and several photos at once. STRAIGHTEN • A perspective engine built on real camera geometry, the mathematics professional desktop tools use. Straight lines come back straight and proportions stay true. • Full, or vertical only. Skewed facades are squared too, not just converging verticals. • Not just buildings: billboards, posters, whiteboards and artwork straighten automatically as well. • Manual Fix for anything the automatic pass cannot read. Drag four corners onto the subject and it flattens square. • Decide what happens to the empty corners: keep them, fill them, or cut them off. Trim sky and foreground too. • Straighten, Crop, Perspective and Adjust in an editor in the style of Photos. Press and hold to compare before and after. • Pick several photos and move between them with the strip under the photo. • Works inside the Photos app as an extension. No exporting, no duplicates. DOCUMENTS • Scan with the built-in camera, one shot per page. AutoAlign finds the page, then crops and straightens it. • Or add pages from Photos and Files. • Every document gets a title and a category, from the on-device model of Apple Intelligence where available: receipts, bills, cards, notes, slides, letters, IDs, or your own. • Search by any word on the page, who sent it, or where you scanned it, in the app or from Spotlight. • Share any document as a searchable PDF. • Date, place and camera are kept on every page. ASK DOCUMENTS, WITH APPLE INTELLIGENCE (EXPERIMENTAL) Ask in your own words: "what was the total on the Hofer receipt?" The answer comes with the document it came from. Nothing is sent anywhere. Uses the on-device model of Apple Intelligence; needs a supported device with Apple Intelligence turned on. Works best in English. WHAT IT KEEPS • HDR. The gain map is corrected alongside the photo, so brightness and colour survive intact. • EXIF, GPS, timestamps and camera settings. • Your original. Every edit is revertible from the Photos app. PRIVATE BY DESIGN No account, no tracking, no analytics. Your photos and documents are processed and stored on your device. LANGUAGES English, العربية, Deutsch, Español, Français, Nederlands, 简体中文. FREE AND PREMIUM Free: the full correction, Manual Fix, cropping, and up to 4 documents. Exports carry a watermark, and photos save at reduced resolution. Premium: full-resolution and HDR export, no watermark, unlimited documents. Monthly, yearly, or a one-time purchase. MADE FOR Architecture, real estate, interiors, cityscapes and travel. Posters, whiteboards and artwork shot at an angle. And the receipts, letters and cards you need to keep. NOTE Automatic correction works best where the scene has clear straight edges. Where it does not, Manual Fix always does.

PersCrop flattens a photo shot at an angle into a straight-on rectangle. Drag the four corners onto your subject and the photo is warped square using a true projective transform — the same maths a scanner's dewarp uses — not a rotation or a stretch. Everything runs on your phone; no photo ever leaves the device. Photograph a whiteboard, a page, a painting or a shop sign and the angle you stood at is baked in: edges lean, corners stretch, the rectangle isn't a rectangle. That is the problem PersCrop was built to solve. Around it sits a small set of tools for the rest of what you do to a photo before posting it. PERSPECTIVE CROP — straighten a photo taken at an angle • Drag four corners onto any four-sided subject: documents, whiteboards, artwork, posters, shop signs • A real homography warp removes the keystone distortion and returns a proper rectangle • Live preview updates as you drag, so you see the result before exporting • Output resolution follows the shape you selected, so detail is kept • Export as PNG, JPEG or WebP NO CROP — fit the whole photo to any aspect ratio • Post the entire photo, with nothing chopped off by a square or vertical frame • Pad to any ratio with a solid color, a gradient, or a blurred copy of the photo itself • Square 1:1, Portrait 4:5, Story 9:16, Classic 4:3, Wide 16:9, plus 3:2, 2:3, A4 paper, 21:9 cinema and 3:1 banner COLLAGE — several photos in one frame • Column, row, grid and diagonal layouts that adapt as photos are added or removed • Adjustable gaps, corner rounding and background color • Pinch and drag inside a cell to position each photo exactly PANORAMA CROP — one wide photo, one seamless carousel • Slice a wide shot into equal panels that line up as the carousel swipes • Choose the panel count and which part of the photo the panels cover GRID CROP — turn an image into a profile mosaic • Cut one image into tiles that rebuild it across your profile grid • Three tiles wide, as many rows as you want • Tiles export in posting order, so the mosaic assembles correctly BUILT FOR PHONES • GPU-accelerated rendering, so previews move with your finger instead of lagging behind it • Light and dark themes that follow your system setting • Save straight to your photo library, or share to any app • Batch save several results in one run PRIVATE BY DESIGN Every crop, warp and export happens on your device. PersCrop has no account, no sign-in, no analytics profile and no server to send photos to. Photo library access is used only to read the picture you pick and to save what you make. It works with no connection at all. WHAT PERSCROP IS NOT It is not a document scanner: there is no OCR, no text recognition and no multi-page PDF export. It straightens and exports images. PERSCROP PRO The core tools are free. Pro is a one-time purchase — no subscription and no recurring charge — and unlocks all tools, the full set of aspect ratios and editing options, and unlimited batch saving. Questions or feedback?
