Image Metadata Editor - Free Online Tool | PivaBox

View and edit EXIF metadata — change date, location, camera settings and more

Image Metadata (EXIF) Editor — View, Edit, and Remove EXIF Data Including GPS Coordinates, Camera Settings, Copyright, and Description from JPEG Images

1. Upload a JPEG image by clicking the upload area or dragging and dropping — the tool only works with JPEG files because EXIF (Exchangeable Image File Format) metadata is embedded in JPEG headers (also present in TIFF and RAW formats, but JPEG is the universal sharing format). EXIF data is created automatically by digital cameras and smartphones at the moment of capture, storing everything from the obvious (date/time, camera model) to the invisible (GPS coordinates, lens focal length, aperture, ISO, shutter speed, white balance, flash mode, and even the camera's serial number). Before sharing photos online, it's wise to review this hidden data — it can reveal your home location, daily routines, and device information.
2. Edit the EXIF fields organized into three logical groups. Basic Info: image description (useful for alt-text generation and DAM system indexing), artist/photographer name, copyright notice (critical for protecting intellectual property — add '© 2024 Your Name. All rights reserved.'), and capture date/time. GPS Info: latitude, longitude (displayed in decimal degrees for easy editing — e.g., 37.7749° N, 122.4194° W for San Francisco), and altitude in meters. You can correct inaccurate GPS data, add location to photos taken with GPS-disabled cameras, or remove location before sharing images of your home or children's school. Camera Settings: make, model, lens, focal length, aperture (f-stop), shutter speed, ISO, and flash status — useful for photographers documenting their technique.
3. Click Save Metadata to download a new JPEG file with all your edited EXIF data embedded, or Remove EXIF to strip all metadata and download a clean JPEG containing only image pixels. Removing EXIF before uploading to social media protects your privacy — most major platforms (Facebook, Instagram, Twitter/X) strip EXIF automatically, but many smaller sites, forums, and direct file shares do not. All editing uses the piexifjs library running entirely in your browser's JavaScript engine — your images are never uploaded to any server, making this safe for sensitive or private photos. The original file on your device remains unchanged.

Frequently Asked Questions

What EXIF data does a typical smartphone photo contain, and what privacy risks does it pose?

A typical smartphone photo contains surprisingly rich EXIF metadata. <strong>GPS coordinates</strong> — precise to within a few meters, revealing exactly where the photo was taken (your home address, workplace, child's school, vacation spots). <strong>Date and time</strong> — when the photo was taken, down to the second. <strong>Device information</strong> — phone model, operating system version, and sometimes the device's unique serial number. <strong>Camera settings</strong> — lens type, aperture, ISO, shutter speed, flash status, and whether HDR or portrait mode was used. <strong>Orientation</strong> — how the phone was held (rotation data that auto-rotates the image when displayed). <strong>Software</strong> — what app processed the image and what editing operations were applied. For privacy: always strip GPS data before sharing photos of your home, family, or locations you frequent. Use the <strong>Remove EXIF</strong> button to strip all metadata at once — this is the safest approach for public sharing. The PivaBox editor processes everything locally — your images never leave your device.

Why would I want to edit EXIF data rather than just remove it? Legitimate use cases for metadata editing?

While privacy-conscious EXIF removal is the most common use case, legitimate EXIF editing serves important purposes: (1) <strong>Copyright protection</strong> — embedding your name and copyright notice in EXIF provides a layer of intellectual property documentation (though it's not legally sufficient alone — register copyrights formally). (2) <strong>Digital Asset Management (DAM)</strong> — adding descriptions, keywords, and ratings to EXIF makes images searchable in photo management software like Adobe Lightroom, Capture One, and Apple Photos. (3) <strong>Photojournalism integrity</strong> — accurate date/time and location data supports photojournalistic credibility; editing GPS to correct inaccurate auto-tagging maintains the documentary value. (4) <strong>Geotagging scans</strong> — adding GPS coordinates to digitized film photos or scanned documents links them to physical locations. (5) <strong>Technique documentation</strong> — photographers document lens, aperture, and settings for educational portfolios. (6) <strong>Forensic analysis</strong> — law enforcement and insurance investigators rely on accurate EXIF timestamps and GPS data. The PivaBox editor gives you full control over this metadata, entirely in your browser.

Does editing EXIF data affect image quality? Will the JPEG be re-compressed when I save?

The tool edits EXIF metadata without re-encoding the JPEG image data itself. EXIF data is stored in the JPEG file's header section (APP1 marker segment), separate from the compressed image pixel data. The tool reads the JPEG, modifies only the EXIF bytes in the header, and writes the result — the actual image pixels (the DCT-compressed data) pass through completely untouched. This means: zero generation loss (no re-compression artifacts), identical image quality to the original, and identical file size except for the small change in EXIF header size. This is fundamentally different from 'Save for Web' or image editing workflows that decode and re-encode JPEG data (each re-encode loses quality). All processing uses the piexifjs library running client-side in your browser — the image bytes never leave your device's memory.
