Stego vs StegInsight

Stego lets you hide private text or images inside ordinary photos and extract them later on your iPhone or iPad. Your cover images and hidden payloads are processed on your device—they are not uploaded to Japality Limited. CHOOSE YOUR WORKFLOW • LSB-1 for lossless PNG workflows • DCT and GN-QIM for JPEG and recompressed sharing scenarios • Social Media Mode to prepare images for apps that may resize uploads • Optional error correction for tougher recovery FEATURES • Hide text, notes, or an image inside another image • Extract hidden content from stego images • UTF-8 support, including Chinese and emoji • Warnings when a cover image is too flat for reliable embedding FREE & STEGO PRO Stego is free to use with ads. Stego Pro (monthly or yearly subscription) removes banner, interstitial, and app-open ads. Payment is charged to your Apple ID. Subscriptions renew automatically unless canceled at least 24 hours before the end of the period. Manage subscriptions in Settings → Apple ID → Subscriptions, or in Stego → Settings → Stego Pro. PRIVACY See our Privacy Policy for how ads (Google AdMob) and subscriptions (RevenueCat) handle data. Steganography operations themselves stay on your device. IMPORTANT Stego is for lawful personal use only. You are responsible for complying with applicable laws. Steganography is not encryption—anyone with the original file may detect or lose hidden data if the image is recompressed.

Discover what lies beneath the surface of your digital images. StegInsight is a multi-platform tool for privacy enthusiasts and security-minded users to analyze and use steganography: hide or reveal text inside images. Key Features • LSB Steganography — Embed or extract hidden text using Least Significant Bit (LSB) encoding in pixel data. Supports UTF-8 text with a clear, consistent protocol. • LSB Bit-Plane Visualization — View the LSB layer of the red, green, and blue channels as grayscale images. Random noise suggests a normal image; regular patterns may indicate hidden LSB data. • Trailing Data Detection — Scan for data appended after the end of image files (EOF). See byte count, hex preview, and decoded text when the trailing data is valid UTF-8. Supports JPEG and PNG. • Dual Embedding Modes — Hide text in pixel LSBs or append it after the file’s logical end (EOF) for JPEG/PNG. Export results as PNG or save back to the photo library (iOS) or file. • Cross-Platform — Same core engine on iPhone, iPad, and Mac with a single, clean interface. • Learn — Built-in short guide to steganography, LSB and EOF concepts, and how to spot hidden content. Whether you’re learning how steganography works or checking whether an image carries hidden data, StegInsight gives you the tools to look under the surface.
