Stego vs TapMask

Stego-Lab labels AI images under the EU AI Act (Art. 50) and adds steganography, EXIF editing, watermarking and batch processing for iPhone, iPad and Mac. It is made for people who want to handle sensitive material locally on their own device, without relying on external servers or cloud services. On the iPhone while travelling, at the desk on the Mac, or flexibly on the iPad — Stego-Lab offers the same capabilities on every platform. Steganography — embed content invisibly With Stego-Lab you can hide text, images or files inside photos and decode them again later. Embedded content can optionally be encrypted with a password. That makes the app suitable for private archiving, protected notes, hidden image information, documented evidence or the controlled handover of content — discreet, secure and entirely offline. Watermarking — visible and invisible Beyond invisible steganography, Stego-Lab also does visible and invisible watermarks. Single images or whole series can be marked with text or image watermarks. In batch mode, many photos are processed in one run — ideal for applying visible, invisible or combined watermarks to entire collections. On the Mac you additionally get comfortable drag-and-drop support and a larger working area. EXIF and metadata editing A second focus is thorough EXIF and metadata editing. Stego-Lab reads, displays and selectively edits image metadata — description, creator, copyright, software, camera make and model, lens data, capture date and GPS information. Metadata can be adjusted and exported under the same or a changed file name. This makes Stego-Lab useful for photographers, archivists, content creators and privacy-minded users who want to stay in full control of their image data. Supported formats Stego-Lab handles the common image formats PNG, TIFF, JPG/JPEG and HEIC, plus many RAW formats. For invisible content and lossless further processing, PNG and TIFF are the formats of choice. On iOS and iPadOS, files come from the photo library or the Files app; on the Mac, the familiar Finder access is available as well. Exported results can be shared, saved directly or fed into existing workflows. Local processing — no cloud, no compromises Stego-Lab works exclusively on your device. Content is never transmitted to external servers. That makes the app particularly attractive wherever privacy, control over your data and offline availability matter. A clear interface for every level of experience The app is organised into Encode, Decode, EXIF, Batch and Info. Newcomers and advanced users alike can run complex image workflows straight on iPhone, iPad or Mac — no extra desktop software required.

TapMask helps you protect private details in screenshots and photos before you share them. Import a photo, take a picture, or send images to TapMask from the iOS Share sheet. TapMask can find text, faces, phone numbers, IDs, and other private details on your device. Tap a detected area to mask it, adjust the box if needed, then export the protected image. Key features: • OCR image text recognition • Automatic text and face detection • Smart face area blur • Irreversible solid redaction for sensitive text • One-tap EXIF and metadata removal • Custom file naming when saving or sharing • Batch export and batch rename with TapMask Pro • On-device image processing with no uploads • No tracking, no analytics SDK, and no data collection • TapMask Pro is a one-time purchase, not a subscription TapMask is designed for everyday privacy edits: chat screenshots, receipts, order numbers, phone numbers, license plates, faces, documents, and other details you do not want to share.
