Frequently Asked Questions
How does the EXIF Data Reader work?
For uploaded images, the exifr library parses binary TIFF IFD structures, EXIF sub-IFDs, GPS tags, IPTC records, and XMP XML embedded in the file. The extracted key-value pairs are normalized into a flat object, then sorted into six predefined categories (camera, exposure, image, GPS, dates, software) using a reverse-lookup map. Numeric tag values like orientation, flash mode, and metering mode are decoded through lookup tables into human-readable labels.
What file types and metadata formats are supported?
JPEG, TIFF, HEIC, WebP, and other image formats supported by your browser. The reader extracts EXIF, IPTC, XMP, and GPS metadata. You can also paste EXIF JSON from any source, including nested IFD groups or flat key-value objects.
Does it warn about GPS location data?
Yes. When GPS tags are detected in the metadata, a warning is displayed. Photos from smartphones often embed precise coordinates that can reveal your location when shared online.
Is my data private?
Yes. All metadata extraction happens entirely in your browser using the exifr library. Your images are never uploaded to any server.
