Image Metadata Editor
View, edit, and remove EXIF metadata from your JPEG images. Edit author, copyright, GPS location, dates, and more — or strip all metadata for privacy. 100% browser-based.
No camera metadata found in this image. Camera fields are read from EXIF and cannot be added manually here — they are recorded by the camera at the time of capture.
Enter latitude and longitude to see a map preview link. Clear both fields to remove GPS from the image.
To remove the GPS location from this image, clear the Latitude and Longitude fields above then click Save Metadata & Download. Or use Strip All Metadata to remove GPS along with all other EXIF data at once.
What This Tool Does
Full EXIF metadata access — read, edit, and remove — entirely in your browser.
How to Use This Tool
Logic Behind the Tool
APP1 segment (marker 0xFFE1), which follows the SOI (Start of Image) marker. The APP1 segment contains a TIFF-formatted block with multiple Image File Directories (IFDs). Editing metadata only requires replacing this segment — the image data in subsequent segments is untouched.piexifjs, a JavaScript port of piexif (Python). piexif.load(dataUrl) parses the APP1 segment into a JavaScript object with keys "0th", "Exif", "GPS". After editing, piexif.dump() serialises the object back to bytes, and piexif.insert() splices them into the original JPEG data URL — preserving the full image payload.51.5074) to DMS rationals on save, and back to decimal on load. Altitude is stored as a single rational with an Altitude Reference byte (0 = above sea level, 1 = below).<canvas> and exporting via canvas.toDataURL('image/jpeg', 0.95). The canvas has no concept of EXIF — its output is a plain JPEG with no metadata headers at all. This is slightly lossy (JPEG re-encode) but removes all embedded data cleanly.Frequently Asked Questions
Modern smartphones embed a significant amount of data in every photo: camera make and model, the exact date and time the photo was taken, GPS latitude and longitude (often precise to within a few metres), altitude, the software version used to process the image, and sometimes a unique device identifier. iPhone photos in particular often include detailed camera parameters — focal length (in 35mm equivalent), aperture, shutter speed, and ISO — as well as the lens model if you use a multi-camera device.
No — for the "Save Metadata & Download" function. EXIF data is stored separately from the pixel data in the JPEG file. piexifjs replaces only the APP1 metadata segment and leaves all the compressed image data segments completely untouched. The downloaded file is pixel-for-pixel identical to the original, just with updated metadata. The only exception is "Strip All Metadata", which re-draws the image on a canvas and re-encodes it as JPEG at 95% quality — this introduces a small amount of quality loss from the re-encoding step.
Several things can strip GPS from a photo before you see it: iCloud and Google Photos can remove location data when you download photos through a browser. WhatsApp, Instagram, and most social platforms strip all EXIF (including GPS) when you download an image you shared or received. Some Android gallery apps remove GPS on export by default. If you downloaded the image from a web service, the GPS was likely already removed. Try opening the image directly from your camera roll or SD card without going through a social platform.
This tool currently processes one image at a time. For batch metadata editing across many files, tools like ExifTool (command line, free) or Adobe Bridge (desktop application) are better suited. ExifTool in particular can apply metadata changes to hundreds of files at once with a single command, making it the standard choice for photographers who need to batch-update copyright or author fields across a shoot.
Yes — almost universally. Instagram, Facebook, Twitter/X, TikTok, WhatsApp, and most other platforms strip all EXIF metadata when you upload an image. This is partly for privacy (to avoid broadcasting GPS locations) and partly to reduce file sizes at scale. The exception is some platforms like Flickr, which preserve EXIF data deliberately as a feature for photographers. If you share images directly (e.g. via email or a file link), the original EXIF is preserved — so stripping metadata before sharing is a good privacy habit.
