MobiPDF: PDF Editor & Scanner

Scanning and OCR: What Works and What Doesn’t

I’ve been using MobiPDF: PDF Editor & Scanner for a few months now, mostly to digitize receipts and business cards. The AI‑powered scanning does a decent job with well‑lit, flat documents—edge detection is snappy, and the auto‑crop rarely misses. But throw in a crumpled invoice or a glossy card, and you’ll see occasional artifacts or skewed angles that require a manual retake. The built‑in OCR (optical character recognition) handles clean printed text reliably, even from scanned photos of book pages. Where it falls short? Handwritten notes. I tried scanning a handwritten meeting summary, and the output was a jumble of misread characters—fine for a rough draft, useless for archival. If your workflow depends on handwritten text, you’ll want a dedicated OCR tool instead.

Editing on a Small Screen

The editing suite inside MobiPDF: PDF Editor & Scanner is genuinely robust for a mobile app. You can add text, images, signatures, or even draw over a PDF with reasonable precision. I regularly fill out tax forms on the go—the fill‑and‑sign feature saves my digital signature, so I don’t have to redraw it each time. The catch? On a phone screen under 6.5 inches, manipulating small text boxes or aligning objects feels cramped. I found myself zooming in constantly, and the undo function (which is present) sometimes lags for a second. If you’re used to desktop‑level PDF editing, expect a learning curve. The app also lets you rearrange pages and merge multiple PDFs, which is handy for consolidating travel documents into one file. Page management is smooth, with a clear visual overview of thumbnails—just don’t expect drag‑and‑drop gestures to work perfectly every time.

The Subscription Reality

Let’s talk money. The free version of MobiPDF: PDF Editor & Scanner gives you basic viewing, scanning, and limited editing—enough for occasional use. But to unlock full OCR, advanced conversion, and the 50 GB cloud storage, you’ll need a Premium subscription. It’s charged annually via Google Play, and auto‑renewal is on by default. I tripped over that the first month. The 5 GB free MobiDrive storage is a nice gesture, but it fills up fast if you scan multi‑page contracts. Also, conversion to Word or Excel preserves layout reasonably well, but complex tables can lose alignment—don’t rely on it for critical spreadsheets. If you rarely edit or convert PDFs, the free tier might be enough; power users should factor in the subscription cost. One more gripe: the app lacks a built‑in batch scan mode, so scanning a stack of documents means tapping “add page” each time. For a tool that otherwise feels polished, that omission stands out.
