Archive-grade
Minimal compression. Every watermark, stamp, and margin note stays pixel-perfect. Ideal for contracts, deeds, and legal PDFs that need to survive a decade.
Most camera apps save a picture of your document. A real PDF scanner produces a document — multi-page, compressed, searchable, and ready for the workflow it's about to enter. Three things separate the two.
Edges detected, perspective straightened, shadows removed. Each scan looks like it came off a flatbed, not out of your pocket. Contracts read like contracts again.
Ten pages of a lease agreement belong in one file, not ten photos in your camera roll. ScanLens batches pages, reorders them, and wraps them as a single multi-page PDF.
On-device OCR drops an invisible text layer behind every page. Cmd-F in any PDF reader finds the clause you need. Copy-paste works. The scan behaves like text.
Every scan is different. Legal archives need every pixel. A receipt for Slack needs to fit under 500 KB. ScanLens gives you control over the quality-to-size tradeoff with three presets — or a custom slider when you need it.
Minimal compression. Every watermark, stamp, and margin note stays pixel-perfect. Ideal for contracts, deeds, and legal PDFs that need to survive a decade.
Smart per-page compression. Text stays crisp; images drop 40–60% without visible loss. The default for 95% of scans.
Aggressive optimisation for tiny files. A 20-page report fits in an email attachment without splitting or zipping.
ScanLens layers an invisible OCR text layer behind every scanned page. The PDF still looks like the original — the page image, the stamps, the coffee ring — but the text behaves like text. Ctrl-F, select, copy, paste. It just works.
On-device OCR runs in 50+ languages, including Chinese, Japanese, Korean, Arabic, and Hebrew. For multi-language pages, ScanLens detects and processes each script independently, so one scan can contain three languages and all of them stay searchable.

PDF/A is the ISO-standard flavour of PDF built for permanent preservation. Fonts, colour profiles, and metadata are embedded inside the file — so the document renders identically in 2026, 2036, and 2050, on any reader, any OS.
When to reach for PDF/A:
Lock a PDF the same way banks lock yours — AES-256 encryption. Set separate passwords for opening versus editing or printing. One tap, two keys.
Scanning, OCR, compression, signing — every step runs on your iPhone's Neural Engine. Documents never touch a ScanLens server, because there is no server.
No analytics SDKs collecting scan metadata. No ad networks watching what you capture. The app does its job and gets out of the way.
ScanLens plugs into iOS's share sheet and every cloud drive you already use. One PDF, seven destinations, zero copy-paste.
Everything — scanning, compression, signing, export — stays inside a single app. No jumping across four tools to produce one signed and archived PDF.
Standard PDF for day-to-day work, plus PDF/A for long-term archival. You choose the format at export — the same scan can produce either output without re-scanning.
Yes. On-device OCR adds an invisible text layer behind every page image, so the PDF stays visually identical to the scan while becoming fully searchable in any reader.
Three presets — Maximum (archive-grade), Balanced (default), Minimum (email-sized) — plus a custom slider. The engine applies different compression to text regions and photo regions within the same page, so you get small files without blurry text.
Yes. AES-256 password protection, set at export. You can require one password to open the document and a separate, stronger password to allow editing or printing.
ScanLens handles long-form capture — entire books and lengthy contracts — and includes a dedicated book-scanning mode with automatic page splitting and dewarp.
