About this app

MetaEXIF is a professional-grade mobile studio for inspecting, modifying, and cleansing EXIF metadata and cryptographic file hashes. Engineered for content creators, photographers, digital marketers, and privacy-conscious users, MetaEXIF empowers you to transform media files into fresh, unique assets while preserving 100% original visual and auditory quality.

WHY METAEXIF?
Modern social media and e-commerce platforms analyze file fingerprints (MD5 and SHA-256 hashes) alongside hidden EXIF tags to detect duplicate uploads, compress media, or track original author devices. MetaEXIF solves this with zero-loss binary mutation, giving each file a verified unique signature without re-encoding or compression artifacts.

KEY FEATURES:

1. COMPREHENSIVE EXIF & METADATA INSPECTION
• Deep inspection of EXIF, IPTC, XMP, and TIFF metadata containers.
• View detailed camera hardware specs: Camera Make, Model, Lens Model, and Firmware.
• Inspect optical exposure metrics: Aperture (f-stop), Shutter Speed, ISO Sensitivity, Focal Length, and 35mm equivalent.
• Hex Byte Dump Viewer for raw binary inspection.

2. ONE-TAP PLATFORM PRESETS
• TikTok Media Preset: Cleanses device tracking signatures and configures metadata for publishing.
• Instagram Reels Preset: Calibrates metadata tags for pristine feed delivery.
• YouTube Shorts Preset: Optimizes container timestamps and bitrate flags.
• E-Commerce Product Photo: Embeds professional product catalog metadata.
• Camera Emulation Profiles: Emulate hardware metadata tags for Sony Alpha 7 IV, Canon EOS R5 C, Fujifilm X-T5, and Apple iPhone 16 Pro Max.

3. TOTAL PRIVACY & GPS LOCATION PURGE
• Remove exact GPS geotags (Latitude, Longitude, Altitude) to protect home or work locations.
• Purge device serial numbers, creator names, software fingerprints, and editing app signatures.
• Audit score gauge (0-100) instantly rates file health before you share.

4. CRYPTOGRAPHIC HASH DELTA ENGINE
• Side-by-side verification of MD5, SHA-1, and SHA-256 signatures before and after mutation.
• Verified [ALTERED] status badge confirms distinct cryptographic uniqueness from original files.
• Zero quality loss: Pure binary byte-level mutation leaves audio-video streams intact.

5. BATCH MULTI-VARIANT GENERATOR
• Generate up to 10 distinct cryptographic variants of a single file in seconds.
• Micro-jitter timestamp offsets ensure every variation receives distinct timestamp and cryptographic values.
• Process queues with sequential batch optimization.

6. 100% LOCAL-FIRST & OFFLINE PRIVACY
• All media parsing, mutation, and hashing happens entirely on your device.
• Zero cloud uploads. Zero remote tracking. Zero server dependencies.
• Operates flawlessly without an active Internet connection.
