What is hidden in a photo?
Phones and cameras save extra information with each photo in a format called EXIF. If location services are on, it includes the latitude and longitude (GPS) where the photo was taken, along with the device make and model, the date and time, and the editing software. Some cameras also store an owner name or serial number.
If you post a photo taken at home on a marketplace, forum or blog without removing this data, someone may be able to work out where you live from the file alone. Many social networks strip it on upload, but email, cloud links and some sites pass the original through unchanged.
What this tool removes
- JPG: EXIF (location, device, date, preview image), XMP, IPTC, comments and extra images appended after the photo. The color profile (ICC) and orientation are kept so the photo stays upright with the same colors.
- PNG: text chunks (tEXt, zTXt, iTXt), EXIF (eXIf) and the modification time (tIME).
- WebP: EXIF and XMP.
- For these three formats the picture data is not re-compressed; only the metadata is cut out, so quality is unchanged. Other formats are re-saved by the browser.
Before you post
- An orange “Location” tag after adding a photo means it contains GPS coordinates.
- To stop adding location to future photos, turn off location access (location tags) for the camera in your phone’s settings.
- Addresses, signs, parcel labels or views out of a window that appear in the picture are not removed by this tool.
- Files are processed only in this browser and never sent to a server.
FAQ
Does it reduce quality?
No. For JPG, PNG and WebP only the metadata is cut out and the picture data is not re-compressed. The file gets slightly smaller.
My photo is sideways after cleaning.
The orientation value is kept, so most apps show it upright. Very old apps may ignore it; rotate and save it with the Image Resizer in that case.
Do messaging apps remove location?
It depends on the app and settings such as “send original”. To be sure, clean the photo here before sending it.
