What EXIF data can reveal
EXIF is a block of data that cameras and phones write into each photo. Besides harmless settings such as shutter speed and ISO, it can hold the date and time to the second, the phone or camera model and sometimes its serial number, the owner’s name, the editing software, and GPS coordinates accurate to a few metres. A photo of your new flat or your child’s school, shared with that data, can show exactly where you live or spend your days.
What this tool removes
The clean copy is built from the picture’s pixels alone, so nothing from the original file’s metadata blocks is carried over: EXIF with GPS location, dates, camera and serial number; the embedded thumbnail, which can show the uncropped original; XMP editing data; IPTC captions and credits; and comments. After saving, the tool reads each JPEG copy again with the same parser to check that no EXIF, XMP or IPTC block remains.
What it does not remove, and other side effects
Metadata is only part of the story. The tool cannot hide what is visible in the picture, such as faces, house numbers, car plates, school badges or a recognisable view from a window, so look at the image itself too. It does not change the file name, and it cannot reach copies you already sent or backed up. The original colour profile is not kept (your browser may add its own standard sRGB profile, which says nothing about you), so wide-colour photos may look very slightly less vivid. JPG and WebP are re-compressed at 92% quality, a small but real loss; PNG stays lossless. Camera orientation is applied to the pixels, so the photo still appears upright.
Do apps and social networks remove it anyway?
Many large social and messaging apps strip location data from the photos they publish, but practices differ and change, and the original upload may still reach the company’s servers. Email attachments, cloud links, file-sharing sites, online marketplaces and documents you send as files usually keep the metadata intact. Cleaning the photo yourself before it leaves your device is the only way to be sure.
Formats, privacy and limits
The detailed viewer reads JPEG files, the format phones and cameras use for most photos; for PNG and WebP the tool still makes a clean redrawn copy but does not list details. Nothing is uploaded, there is no account and no daily cap, and you can process up to about 200 MB of photos in one go. Related tools:
