Messaging Apps

WhatsApp: Strips EXIF for privacy. iMessage/SMS: May preserve metadata. Email: Preserves all EXIF. Strip before sending if uncertain.

Cloud Storage

Google Photos, iCloud, Dropbox: All preserve EXIF for organization. Good for backups, risky when sharing links. Strip before sharing.

Marketplaces

eBay, Craigslist, Facebook Marketplace: Don't strip EXIF automatically. ALWAYS remove before uploading product photos to prevent location exposure.

Advanced EXIF Analysis

Lens Performance Testing

Professional photographers use EXIF to scientifically test their lenses. By analyzing EXIF from test shots at different apertures (f/2.8, f/5.6, f/11, f/16), you can identify the "sweet spot" where your lens is sharpest. Compare sharpness, distortion, and vignetting across the focal length range. Build a personal database of how each lens performs under different conditions.

Exposure Consistency Analysis

Review EXIF from multiple shoots to identify systematic exposure issues. If you consistently underexpose by 1 stop, adjust your exposure compensation. Check histogram data embedded in EXIF to verify proper exposure distribution. This data-driven approach improves technique faster than guesswork.

ISO Performance Evaluation

Determine your camera's acceptable noise ceiling by reviewing EXIF from high-ISO shots. Compare noise levels at ISO 3200 vs 6400 vs 12800. Identify when to prefer a faster lens over higher ISO. Build confidence using higher ISOs when necessary through objective assessment.

Autofocus Accuracy Tracking

EXIF reveals which AF points were used and their success rate. Identify problematic focus modes or scenarios. Determine whether center point is more accurate than outer points. Subject distance data helps diagnose near/far focus issues. Systematic analysis dramatically improves focus technique.

Professional Photography Applications

Wedding Photography

Wedding photographers use EXIF to maintain consistency across thousands of shots. Review EXIF from successful ceremonies to replicate lighting and exposure. Identify which lenses work best for different wedding moments (wide for venue, telephoto for ceremony details). Build shot lists based on proven EXIF data from past weddings.

Wildlife Photography

Wildlife shooters rely on EXIF to perfect their technique. Analyze shutter speeds needed to freeze different animal movements (1/2000s for birds in flight, 1/500s for running mammals). GPS data helps return to productive shooting locations. Track which focal lengths capture best compositions for different species.

Landscape Photography

Landscape photographers use EXIF to plan future shoots. GPS coordinates mark successful locations for different seasons and lighting. Timestamp data reveals optimal shooting times. Exposure settings guide HDR bracketing sequences. Build a location database with proven settings for each spot.

Portrait Photography

Portrait photographers analyze EXIF to perfect their lighting ratios. Review successful portraits to identify ideal apertures for different looks (f/1.4 for dreamy bokeh, f/5.6 for group shots). Track which focal lengths are most flattering (85mm vs 135mm). Maintain consistency across portrait sessions.

Technical Details

How Viewing Works

This viewer uses the EXIF.js library to read metadata directly in your browser. The image is processed locally using JavaScript - nothing is uploaded to our servers. All EXIF tags are extracted and displayed in an organized table format. The FileReader API loads the image, EXIF.js parses the binary data, and results display instantly.

How Removal Works

We use the HTML5 Canvas method: load image → redraw pixels on canvas → export as new JPEG. Canvas naturally excludes all metadata. High-quality encoding (95%) preserves visual quality while stripping all EXIF data. The process is: FileReader loads image → Canvas draws pixels → toBlob exports clean JPEG → Download link created.

Supported File Types

• JPEG/JPG: Full EXIF support, most common format. Contains complete metadata including GPS, camera settings, and editing history.
• TIFF: Complete EXIF including professional fields. Often used by professional photographers for archival quality.
• RAW formats (CR2, NEF, ARW): Contain extensive EXIF plus proprietary camera data. Require specialized tools beyond this web-based viewer.
• PNG: Limited metadata support, not full EXIF. Uses different metadata standards (tEXt, iTXt chunks).
• HEIC/HEIF: Modern Apple format with EXIF support. Growing adoption but limited browser support for viewing.

EXIF vs XMP vs IPTC

EXIF: Camera-generated technical metadata (settings, GPS, timestamps). XMP: Adobe's extensible metadata platform for editing software. IPTC: Journalism-specific metadata (captions, keywords, copyright). All three can coexist in a single image file. Comprehensive tools display all metadata types.

Forensic & Legal Applications

Digital Forensics

Law enforcement uses EXIF to establish photo timelines and verify authenticity. GPS data places subjects at specific locations during investigations. Modification timestamps reveal tampering or editing. Inconsistent EXIF indicates possible forgery. Camera serial numbers link images to specific devices. Critical evidence in criminal and civil cases.

Copyright Disputes

Original EXIF proves photo ownership and creation date. Camera serial number links image to specific photographer. Edit history shows work progression and originality. Missing or altered EXIF raises authenticity questions. Courts increasingly rely on EXIF as evidence in infringement cases.

Insurance Claims

Timestamp proves when damage occurred. GPS location confirms claim location accuracy. Detailed technical data validates claimed photography equipment. Unaltered EXIF strengthens claim legitimacy. Insurance adjusters increasingly verify EXIF to prevent fraud.

News Verification

Journalists verify photo date/location matches reported events. Detection of old photos republished as current news. GPS confirms authenticity of on-scene reporting. Deepfake and AI-generated images often lack consistent EXIF. Metadata crucial for combating misinformation in digital age.

Camera-Specific Considerations

DSLR & Mirrorless Cameras

Professional cameras record the most comprehensive EXIF data. Extensive technical settings including custom functions. Lens electronic contacts provide detailed lens data (focal length, aperture, image stabilization status). Some cameras embed GPS via external units. Maximum metadata for professional analysis.

Smartphones

Always include GPS unless specifically disabled in settings. Less detailed technical EXIF than dedicated cameras. Computational photography features noted in metadata (HDR, Night Mode, Portrait Mode). Face detection and scene recognition data. Privacy concerns highest due to constant GPS tracking.

Action Cameras (GoPro, DJI)

Include accelerometer data showing movement and G-forces. GPS tracking for action sequences and routes. Video metadata in addition to still image EXIF. Environmental sensors (altitude, temperature, barometric pressure) in some models. Unique metadata for action sports documentation.

Drones

Comprehensive GPS data including altitude and flight path. Gimbal orientation and camera angle. Flight telemetry embedded in metadata. Critical for aerial photography planning and legal compliance. Privacy concerns when flying over private property.

Troubleshooting Common Issues

No EXIF Data Found

Causes: Screenshot images, social media downloads, previously stripped photos, PNG files. Solution: Only JPG and TIFF files contain full EXIF. Try the original unedited file from your camera or phone.

Incomplete EXIF Data

Causes: Some editing software strips certain fields. Older cameras record less metadata. Solution: Check original camera file. Different cameras record different EXIF fields - this is normal.

Removal Not Working

Causes: Browser compatibility issues, file format not supported. Solution: Try different browser (Chrome, Firefox recommended). Ensure file is JPG format. Check browser console for errors.

Quality Loss After Removal

Causes: JPEG re-encoding causes slight quality degradation. Solution: This is normal and minimal (95% quality). For critical work, keep original with EXIF and only strip copies for sharing.
