Tiny Scanner - PDF Scanner App
Overview
Tiny Scanner - PDF Scanner App is an established, high-performance document digitization utility developed by TinyWork Apps. Trusted for over a decade by small business owners, students, and remote professionals, the application transforms a device's camera into a portable, high-speed document scanning system.
At its core, Tiny Scanner utilizes proprietary computer vision and AI-powered border detection to automatically isolate documents, crop perspectives, and correct geometric distortions from skewed capture angles. The image processing pipeline includes professional filters optimized for black-and-white contrast, grayscale transitions, and color enhancement, ensuring that scanned text remains sharp, legible, and highly compressed for rapid sharing. For complex workflows, Tiny Scanner features a batch-scanning mode that enables users to continuously capture multi-page documents without back-and-forth navigation.
Beyond basic capturing, Tiny Scanner has evolved into a robust administrative document manager. It offers on-device OCR (Optical Character Recognition) to extract, copy, and convert printed text into editable Word, Excel, or plain text formats. Specialized AI-powered tools provide immediate document summaries, key entity extraction, and content refinement. Furthermore, the app integrates dedicated scanning modes for passports and government IDs, an interactive length and area measurer, an object counter, and a real-time math problem solver. Document security is handled via local PDF passcode encryption, application-wide locking, and secure folder vaulting.

FAQs
Does Tiny Scanner support text extraction from scanned images?
Yes. The application features an AI-powered OCR (Optical Character Recognition) tool that can extract text directly from scanned documents, allowing users to copy, edit, or export the content as Word or Excel files.
Is my scanned data secure within the application?
Yes. Tiny Scanner prioritized local data security by allowing users to encrypt specific folders, set application-wide password locks, and add password encryption directly to shared PDF files.
Why can't I scan or export more than three documents?
The free version of Tiny Scanner is designed for basic evaluation and limits users to three documents. Unlimited scans, batch scanning, and advanced AI features require a paid upgrade to the Pro tier.
Can I sign documents directly on my phone using Tiny Scanner?
Yes. The app includes built-in signature tools, enabling users to draw a signature directly on the screen or scan a physical ink signature to place on documents.
Why is Tiny Scanner incompatible with my older Android phone?
To protect private information and maintain secure cloud syncing, Tiny Scanner requires modern data security protocols that are no longer supported on older operating systems like Android 7.1 and below.
Hot Reviews
Summarized from Google Play reviews and community discussions.
The scanner works incredibly fast, but the monetization approach is highly frustrating. Being prompted to purchase a premium subscription while frantically scanning urgent tax documents, only to discover a strict three-document limit, is a highly stressful user experience. The app should make its free limits clearer upfront.
For business travelers, this application is a vital utility. It instantly transforms paper documents and receipts into professional, high-contrast PDFs. The automatic edge cropping works flawlessly even in poorly lit environments, making it a reliable backup to flatbed scanners.
The text recognition engine is highly accurate. Converting hand-written printed text or receipts into fully editable Word documents takes seconds, and the formatting is largely preserved. The newly added AI summarizer is also exceptionally helpful for quickly parsing long contracts.
