Reliable OCR for Everyday Documents
Urdu Image OCR is a free online tool that uses optical character recognition (OCR) to pull Urdu text from images like JPG, PNG, TIFF, BMP, GIF, and WEBP. It supports Urdu OCR with free single-image runs and optional bulk OCR for larger jobs.
Our Urdu Image OCR solution helps you digitize Urdu writing from scanned pictures, screenshots, and mobile photos using an AI-driven OCR engine. Upload an image, choose Urdu as the language, and convert the content into selectable text you can copy or export as plain text, Word, HTML, or searchable PDF. It’s designed for Urdu script (right-to-left) and common letter-joining behavior, improving results on clear printed Urdu found in forms, notices, and document captures. The free version processes one image per run, while premium bulk Urdu OCR supports larger image sets. No installation is needed—everything runs in your browser, and uploads are removed after processing.Learn More
The NanoVNA family of vector network analyzers put powerful RF measurement tools into the hands of makers, ham radio operators, and RF tinkerers. Paired with NanoVNA‑Qt — a modern, actively developed desktop application — and an S‑A‑A‑2 antenna analyser adapter (SAA2) or similarly named serial adapter used to interface older NanoVNA hardware, you get a streamlined workflow for calibration, sweeping, and saving measurements for analysis and antenna tuning. This post walks through setup, practical tips, and common workflows so you can get accurate S11/SWR and impedance plots with minimal fuss.
Device Recognition: Open the software and go to the Device menu. Select Connect to VNA. You should see a serial port (e.g., COM3 on Windows or /dev/ttyUSB0 on Linux). nanovna-qt pc software with the s-a-a-2
