Frequently Asked Questions
Find everything you need to know about professional image processing.
1What is image metadata and EXIF data?
Metadata is hidden information embedded in image files. EXIF (Exchangeable Image File Format) includes camera settings like ISO, aperture, shutter speed, date/time, and GPS location. This data helps photographers track shooting conditions and organize photos efficiently.
2Which file formats support metadata?
JPEG/JPG files have the most complete EXIF support. TIFF, PNG, and RAW formats (CR2, NEF, ARW) also contain metadata. Our tool currently focuses on JPEG files for viewing and editing EXIF data, as they're the most commonly used format with full metadata support.
3Can I edit or remove metadata from my photos?
Yes! Our tool lets you edit specific EXIF fields like author, copyright, and description. You can also completely remove all metadata with one click to protect your privacy before sharing images online. All processing happens securely in your browser.
4Why should I remove metadata before sharing photos?
Photos often contain sensitive information like GPS coordinates showing where you live or work, camera serial numbers, and timestamps. Removing metadata protects your privacy by preventing others from accessing this personal information when you share images on social media or websites.
5Is my data safe when using this tool?
Absolutely! All metadata viewing and editing happens entirely in your browser using client-side JavaScript. Your images are never uploaded to our servers. Your files remain completely private and secure on your device throughout the entire process.
6What camera information can I see in EXIF data?
EXIF data reveals comprehensive camera settings including ISO sensitivity, aperture (f-stop), shutter speed, focal length, flash usage, white balance, metering mode, and exposure compensation. You'll also see camera make/model, lens information, and shooting date/time.
7Can I view GPS location data in photos?
Yes, if GPS was enabled when the photo was taken. Our tool displays GPS coordinates, altitude, and even provides a map link to visualize the exact location. This feature is particularly useful for travel photography and geotagging workflows.
8Does this tool work offline?
Yes! Since all processing happens in your browser, you can use our metadata viewer and editor even without an internet connection (after the initial page load). Your images never leave your device, making it perfect for privacy-conscious users.
9Can I add copyright information to my images?
Definitely! Use our metadata editor to add or modify copyright notices, author names, descriptions, and keywords. This helps protect your intellectual property and makes images more discoverable. The edited metadata stays embedded in your downloaded file.
10What's the difference between viewing and editing modes?
View mode displays all existing metadata in an organized, readable format with all camera settings and photo details. Edit mode lets you modify specific fields, add new information, or completely strip all metadata. You can switch between modes anytime during your workflow.
