In today's digital world, your photos contain more than just memories—they contain personal information, location data, and sometimes sensitive content. When converting image formats online, understanding privacy and security implications is crucial for protecting your digital assets.
Understanding Privacy Risks
Server-Side Processing Risks
- • Your images are uploaded to external servers
- • Files may be stored temporarily or permanently
- • Potential access by unauthorized parties
- • Data breach vulnerabilities
- • Unclear data retention policies
Client-Side Processing Benefits
- • Images never leave your device
- • Complete control over your data
- • No server storage or logging
- • Zero data breach risk
- • Works offline after initial load
What is Client-Side Processing?
Client-side processing means your browser performs the image conversion locally on your device, without sending files to any external servers.
How Client-Side Conversion Works
-
1JavaScript Engine: Modern browsers have powerful JavaScript engines that can process images directly in memory
-
2File Reading: The FileReader API allows JavaScript to read image files without uploading them
-
3Canvas Processing: HTML5 Canvas element renders and processes images in the browser
-
4Format Conversion: Browser converts between image formats using built-in codecs
-
5Download: Converted images are made available for download without server involvement
EXIF Data and Metadata Protection
What is EXIF Data?
EXIF (Exchangeable Image File Format) data is metadata embedded in your photos that can include:
Technical Information
- • Camera make and model
- • Camera settings (ISO, aperture, shutter speed)
- • Image dimensions and resolution
- • Date and time photo was taken
- • Flash settings and focus mode
Personal Information
- • GPS coordinates (location data)
- • Device serial numbers
- • User comments and keywords
- • Copyright information
- • Software used for processing
Privacy Risk: Location data in EXIF can reveal where photos were taken, potentially exposing your home address, workplace, or travel patterns.
EXIF Data Handling Options
Strip All EXIF
Remove all metadata for maximum privacy, especially for sharing online.
Selective Removal
Remove only sensitive data like GPS coordinates while keeping camera settings.
Preserve All
Keep all metadata for professional or archival purposes when privacy isn't a concern.
