ScreenStack Screenshot Manager vs ID2PDF

ScreenStack is an AI-powered screenshot manager that helps you get screenshots in, find what matters, use the information inside them, and clean up with confidence. Local-first by design, with optional AI enhancement. SHARE FROM ANYWHERE Use the system share sheet in any app to send a screenshot or photo straight into ScreenStack—verified working from Photos, WeChat, and similar sources. AI SORTING Open the app to a visual screenshot wall. New imports are routed into Important, Saved, Quick, or To Review. Your rules come first; uncertain items stay honest instead of being forced into the wrong category. Correct a suggestion once and ScreenStack remembers. INSTANT OCR SEARCH On-device OCR turns screenshot text into searchable information. Find verification codes, order numbers, Wi-Fi passwords, amounts, and tracking numbers in about half a second—and copy the field you need, not just the image. OPTIONAL AI, YOUR KEY Connect your own API key from 17+ model providers for more detailed classification and extraction. Your provider, model, and rules stay under your control. Core features work without a key. SAFE CLEANUP Review extracted fields before deleting. Soft-deleted screenshots go to a trash folder, while saved credentials and favorites can keep an original backup. SAFE BACKUP & RESTORE Export a free, offline backup that preserves original image copies, OCR text, extracted fields, notes, tags, and organization status. Restoring verifies the file, then merges it non-destructively—nothing is lost when you switch devices or reinstall. SCREENSTACK PRO Smart Cleanup groups visually similar screenshots and identifies expired credentials. Credential Wallet adds expiry reminders and batch CSV export. One-time purchase, no subscription. PRIVACY FIRST OCR, search, and organization run on your device. Original screenshots never leave it. Only when you enable AI and provide your own key are extracted words sent to the provider you choose. Import, organize, search, and basic cleanup are free forever.

ID2PDF does one thing well: scan your ID documents and print them at their real size. Photograph an ID card, passport, visa, household register, driver's license, or residence permit. ID2PDF finds the edges, straightens the perspective, removes shadows, pairs the front and back onto the same page, lays everything out at true 1:1 physical size on A4, Letter, or A3, and exports a print-ready PDF in one tap — all on your device. WHAT MAKES IT DIFFERENT • Clean scans, automatically — automatic edge detection, perspective correction for photos shot at an angle, adjustable shadow removal, plus Enhanced and Grayscale modes. Tidy copies with no manual trimming. • Front and back on one page — shoot both sides in a row, or import them together from Photos. ID2PDF recognizes which side is which, pairs them into one document, and puts them on the same page by default. • Several IDs from one photo — lay a few documents on the table, take a single shot, and ID2PDF splits them into separate documents (up to 6) in reading order. • True-to-size output — every document is laid out to the millimeter, so the print comes out exactly as large as the real thing. Presets cover the ID-1 card (85.6×54mm), the visa sticker (105×74mm), and the passport data page (125×88mm), and you can define any size from 20 to 300mm. Full-page sizes like A4, Letter, and A5 switch to edge-to-edge printing, just like a copier. • 1 to 8 documents per page — 10 layouts, adjustable spacing, long-press to drag and reorder. Print a whole stack at once and save paper. • Watermarks, free — presets such as "For this application only", with adjustable color, opacity, and density, tiled diagonally across the page so copies can't be reused elsewhere. • Face ID protection — optionally require Face ID or Touch ID to open the app; the screen blurs when you switch away, so the app-switcher thumbnail never shows your documents. • 100% on device — capture, recognition, layout, and PDF generation all run locally. Scanning and processing need no network, nothing is uploaded, and there's no account to create. WHAT YOU SEE IS WHAT YOU PRINT The page canvas on the home screen and the exported PDF share the same millimeter layout engine, so the positions, sizes, and watermark you see are exactly what comes out of the printer. Any crop the detector isn't sure about is flagged in orange, and you get one last confirmation before exporting. MADE FOR • Printing ID, passport, or visa copies for paperwork, reimbursements, school, a new job, or a lease • Getting both sides of an ID onto one page without flipping it on a copier • Fitting several documents on one page for batch copying and filing • Keeping your go-to documents in a project, ready to re-export anytime YOUR FILES STAY WITH YOU Projects are saved locally, can be renamed or deleted anytime, and can auto-clear after 7 or 30 days if you prefer. No iCloud sync, no photo uploads. ABOUT PRO Capture, Photos import, auto-cropping, multi-card splitting, front/back pairing, all 10 layouts, watermarks, live page preview, project history, and Face ID protection are free — with no usage limits, no forced watermark, and no ads.
