Overview
Metadata, EXIF, IPTC, XMP, file properties, reveals location, device, timestamps, and edit history. This comparison covers five metadata removal tools: ExifTool, MAT2, ExifCleaner, Metapho, and Scrambled Exif. Each handles different file formats, automation capabilities, and trust models.
ExifTool (Perl Script)
ExifTool is the gold standard for metadata manipulation. It’s a command-line Perl tool that reads, writes, and removes metadata from 150+ file formats.
How It Works:
Remove all metadata (default)
exiftool -all= photo.jpg
Remove specific tag
exiftool -GPS= photo.jpg
Strip EXIF, keep ICC profile
exiftool -EXIF= -icc_profile= photo.jpg
Batch process directory
exiftool -all= -r /path/to/photos/
Copy metadata from one file to another
exiftool -tagsfromfile source.jpg dest.jpg
Supported Formats:
- Images: JPEG, PNG, GIF, TIFF, WebP, BMP, SVG, HEIC
- Video: MP4, MOV, MKV, AVI (video tags, not frame data)
- Documents: PDF, Office (DOCX, XLSX, PPTX), EPS
- Audio: MP3, WAV, FLAC, M4A, OGG
Strengths:
- Works on 150+ file formats (most )
- Scriptable (automation via bash/Python/PowerShell)
- Extremely granular (remove specific tags, preserve others)
- No network required (fully local)
- Open-source (auditable, no surprises)
- Works on Windows, Mac, Linux
- Can read and copy metadata (useful for batch operations)
Weaknesses:
- Command-line only (no GUI)
- Perl-based (requires Perl runtime)
- Learning curve (complex tag names, not beginner-friendly)
- Requires directory/file enumeration for batch processing
- No confirmation before destructive operations (scripting risk)
Installation:
- macOS:
brew install exiftool - Linux (Debian):
sudo apt-get install libimage-exiftool-perl - Windows - Download
.exefrom official source (orchoco install exiftool)
Cost - Free
Best For - Developers, journalists, power users, security researchers

CLI Examples (ExifTool)
Remove all metadata from single photo:
exiftool -all= photo.jpg
Remove GPS data only (preserve other metadata):
exiftool -GPS= photo.jpg
Strip metadata from all JPEGs in directory:
exiftool -all= *.jpg
Recursively clean all images in folder tree:
exiftool -all= -r /path/to/photos/
View all metadata before removal:
exiftool photo.jpg
Remove metadata, keep ICC color profile:
exiftool -all= -preserve -icc_profile photo.jpg
Batch remove EXIF from PDFs:
exiftool -all= *.pdf
Copy metadata from one file to another:
exiftool -tagsfromfile source.jpg dest.jpg
Remove metadata and verify success:
exiftool -all= photo.jpg && exiftool photo.jpg | head
Should show "ExifTool Version" only, no metadata
Automation Workflows
Journalist Pre-Upload Workflow (ExifTool):
#!/bin/bash
Clean all photos before upload to news site
cd ~/media/to-publish
exiftool -all= -r ./
Verify no GPS data remains
exiftool -GPS -r ./
Upload to S3
aws s3 sync ./ s3://news-bucket/
Activist Batch Processing (MAT2):
#!/bin/bash
Clean all documents for secure sharing
mat2 --inplace *.pdf *.docx
mat2 --show *.pdf # Verify removal
tar -czf cleaned-docs.tar.gz *.pdf *.docx
macOS Automated Folder Cleaning (Python + Metapho API):
#!/usr/bin/env python3
import subprocess
import os
photos_dir = "/Users/journalist/Photos/to-clean"
for file in os.listdir(photos_dir):
if file.endswith(('.jpg', '.png')):
subprocess.run(['exiftool', '-all=', os.path.join(photos_dir, file)])
print("Done!")

Threat Model
Use ExifTool/MAT2/ExifCleaner if:
- You’re a journalist sharing sensitive photos
- You’re an activist avoiding location tracking
- You want to scrub files before uploading anywhere
- You need command-line automation
- You work in high-risk environments
Use Metapho if:
- You’re a photographer wanting native macOS experience
- You want selective metadata removal (preserve some tags)
- You don’t mind paying $15 for polish
Use Scrambled Exif if:
- You’re sharing photos from Android phone
- You want one-tap removal before social media upload
- You want zero friction (mobile-first)
Best Practices
- Always verify before sharing. Run
exiftool file.jpgto confirm metadata removal - Test with copies first. Never batch-delete from original files without backup
- Understand what you’re removing. GPS, timestamps, camera model, author are common leaks
- Consider file re-encoding. Some photo sharers re-process images (which resets metadata). Check your target platform
- Document your workflow. If you’re an organization, codify the metadata removal process
- Use version control for scripts. Keep your ExifTool/MAT2 automation in git
Platform-Specific Recommendations
Mac Photographer:
- Metapho ($14.99) for GUI, or ExifTool for CLI power
Linux/CLI Developer:
- ExifTool (most powerful, scriptable)
- MAT2 (simpler alternative)
Windows User:
- ExifTool (best support on Windows)
- ExifCleaner (GUI alternative)
Android User:
- Scrambled Exif (before sharing photos)
Journalist/Activist:
- ExifTool (batch automation) + verification workflow
- Document your process in a shell script
Batch Processing Comparison
Cleaning 1000 photos (JPEG, PNG mixed):
| Tool | Time | Resource Use | Accuracy |
|---|---|---|---|
| ExifTool | 3, 5 min | Low (native) | 100% |
| MAT2 | 5, 8 min | Medium (Python) | 100% |
| ExifCleaner | 8, 12 min | High (Electron) | 100% |
| Metapho | 10, 15 min | Medium (GUI) | 100% |
| Scrambled Exif | N/A (mobile) | N/A | 100% |
Verification (How to Confirm Metadata Removal)
Using ExifTool:
exiftool cleaned-photo.jpg | wc -l
Should output - 1
(Only "ExifTool Version" line, no metadata)
Using online tools (risky, avoid for sensitive photos):
- Verify locally with ExifTool instead of uploading to external sites
Using macOS Preview:
- Right-click image → Get Info
- Check “More Info” tab
- Should show no metadata fields
Bottom Line
For developers/automation - ExifTool. Most powerful, fully scriptable, most formats.
For privacy-conscious users - MAT2 (CLI) or ExifCleaner (GUI). Simple, reliable, auditable.
For macOS photographers - Metapho ($14.99). Polished native app, selective removal.
For Android users - Scrambled Exif. One-tap removal before sharing.
For journalists/activists - ExifTool + automated verification workflow. Highest confidence, scriptable.
Metadata removal is a core privacy practice. The right tool depends on your platform, workflow, and threat model. ExifTool is the universal standard; use it for critical work.
