Detaggo gives you full control over your image metadata — view every hidden tag, edit what you need, strip what you don't, and protect your work with advanced watermarks. All in one app that runs entirely on your device.
🔍 VIEW & EXPLORE METADATA
Open any image to see all its embedded metadata, organized into clear categories: camera info, shot settings, date, GPS location, software, XMP, IPTC, C2PA, maker notes, and more. Search and filter by category. AI-content indicators and GPS coordinates are surfaced at a glance.
✏️ EDIT & ADD TAGS
Tap any tag to edit values across 14+ categories (camera, shot settings, GPS, date/time, description, custom, and more), with inputs matched to each data type. Add new tags from the EXIF catalog or create your own. Save as a copy or overwrite the original.
📋 COPY METADATA BETWEEN IMAGES
Copy all metadata or pick specific fields from a source image to one or many target images in a single pass.
🕓 TIMEZONE DETECTION & FILLING
Derive the image's timezone from GPS reverse geocoding, EXIF offset, or XMP using confidence-weighted methods, then fill the missing pieces automatically.
🤖 AI CONTENT DETECTION
Scan images for AI-generation signals across 11+ signatures, including DALL·E, Midjourney, Stable Diffusion, Adobe Firefly, and more — each with a clear confidence rating.
🧹 STRIP AI METADATA
Choose what to remove: AI tags only, AI + C2PA, AI + software signatures, or a full metadata wipe. Preview the tag count and file-size savings before applying.
💧 IMAGE WATERMARKING (PREMIUM)
Protect your work with multiple watermark styles:

- Visible overlay: text or logo with control over size, opacity, rotation, blend mode, and tiling
- Blind DCT: embed an invisible payload that survives JPEG re-compression; extract without a key
- Keyed DCT: hide a payload behind a shared passphrase so only the correct key can recover it
- RSA-2048 digital signature: sign with a private key, verify authenticity and integrity with the public key, export a PDF verification report
- Watermark verification: detect and verify embedded robust watermarks; verification history preserved
- Key management: generate, import, export, and switch keypairs, with encrypted backup to Google Drive
- Watermark Vault: store watermark configurations and thumbnails for later re-editing

📍 VIEW & EDIT GPS
View, edit, or delete coordinates (latitude, longitude, altitude, speed, direction). Pick coordinates on a map, or open in your system maps app.
🔒 ENCRYPTED VAULT
Store sensitive images in a local encrypted vault. Choose full-image storage or thumbnail-plus-reference mode.
☁️ GOOGLE DRIVE BACKUP
Sign in with Google to bi-directionally sync vault entries, watermark keys, and history. Conflicts are detected with user-controlled resolution.
📦 BATCH PROCESSING
Operate on many images at once — strip metadata, AI tags, or GPS, or add tags — with per-image success/failure reporting.
🎨 DESIGN & LANGUAGES
A modern Material 3 interface with light, dark, system, and dynamic-color themes. Available in English, Thai, and Vietnamese.
🛡️ PRIVACY FIRST
Everything runs on your device. No images are uploaded. No data leaves your phone.
Detaggo — De-tag and go.
