Every photo you take is two things in one file: the picture, and a block of information your camera wrote beside it - when the shutter opened, which camera and lens took the shot, and, if location services were on, where you were standing. That block travels with the file. Email the photo, put it in a marketplace listing or send it as a document rather than an image, and it goes too. This guide covers what is in there, how to read it, and how to strip it without touching a single pixel, using the EXIF Viewer & Remover.
What EXIF actually records
EXIF (Exchangeable Image File Format) is the standard cameras and phones use to write technical information inside an image file. It is not the only such block - editing software adds XMP, and news and stock workflows add IPTC for captions, credits and keywords - but it holds the most. A typical phone photo carries some mixture of:
- Date and time the photo was taken, and often a second timestamp for the last edit.
- Camera make and model, frequently the lens, and on many bodies a serial number.
- Exposure settings: shutter speed, aperture, ISO, focal length, flash and white balance.
- Orientation, colour space and resolution - which is how a photo shot sideways still displays the right way up.
- GPS latitude, longitude and often altitude, if the camera app had location access.
- A small embedded preview, which is why the block is sometimes tens of kilobytes rather than a few.
Most of that is harmless and genuinely useful. Two parts are not: the location, and anything identifying a specific device or person.
Why the GPS tag is the one that matters
A camera serial number links photos to each other - post enough shots and they are provably from the same body. That is a slow, indirect problem. Coordinates are an immediate one, because they are precise enough to be an address.
One degree of latitude is about 111 kilometres, so a coordinate written to six decimal places resolves to roughly 11 centimetres. Consumer GPS is nowhere near that accurate - a phone fix is typically good to three to ten metres - but that is still the difference between a street and a doorway. And the photos people share most freely are the ones taken at home: the item for sale on the kitchen table, the pet on the sofa, the child in the garden. Each carries the same coordinates.
A worked example: reading a set of coordinates
Load a photo into the EXIF Viewer & Remover and, if it has a location, the first thing you see is a pair of decimal numbers - say 28.613333, 77.208889 - with the same position underneath in the degrees, minutes and seconds form maps apps use.
The conversion is straightforward. The whole number is the degrees: 28. Multiply the remainder by 60 for the minutes: 0.613333 x 60 = 36.8, so 36 minutes. Multiply that remainder by 60 for the seconds: 0.8 x 60 = 48. The latitude is 28 degrees 36 minutes 48 seconds north. Run the longitude the same way - 0.208889 x 60 = 12.53, then 0.53 x 60 = 32 - and you get 77 degrees 12 minutes 32 seconds east. The tool prints both forms so you can paste either into a map and see what your photo has been telling people. It does not look the position up for you: that would mean sending your coordinates to a mapping service, the very thing you came here to stop.
What strips EXIF, and what quietly does not
Large social platforms generally re-encode uploads and drop the metadata in the process, so the copy other users can download is usually clean. That is a narrower guarantee than it sounds: the platform still received the original, the behaviour is theirs to change, and it says nothing about the other routes a photo takes out of your phone.
Those routes are the ordinary ones - email attachments, cloud share links, marketplace listings, and chat apps when you send as a file rather than as a photo. Anywhere you hand over the actual file instead of letting a service rebuild it, the metadata goes too. Strip it before the file leaves your machine and it stops mattering what the receiving end does.
Checking and removing EXIF, step by step
- Drop a JPG, PNG or WebP onto the EXIF Viewer & Remover, or click to choose one. The file is read on your own device and never uploaded.
- Read the summary. Location comes first and highlighted if present, then camera, lens, timestamps, exposure settings and any software that touched the file.
- Click 'Show all tags' for the complete list, grouped into location, camera, capture settings, IPTC and XMP.
- Click 'Download clean copy'. You get a new file with a -clean suffix; the original on your disk is untouched.
- The tool reports how much came off - say 14.2 KB down to 13.8 KB. Load the clean copy back in to confirm it now reads as empty.
Why removing it doesn't cost any quality
This surprises people, because the obvious way to clear metadata - open the photo in an editor and save a copy - does cost quality. Saving a JPG re-runs the compression, which is lossy every single time, so each round trip softens detail slightly.
Stripping metadata properly does not go near the pixels. A JPG is a sequence of labelled segments: one holds the compressed image data, others hold EXIF, comments and colour information. PNG and WebP are sequences of labelled chunks on the same principle. Removing metadata means rewriting the container without the blocks that hold it and copying the compressed image data across byte for byte - nothing decoded, nothing re-compressed, and a picture bit-for-bit identical to the one you started with. The file is simply smaller.
What is deliberately left in
Not every non-pixel block is metadata about you. The colour profile describes how the numbers in the file map to actual colours, and dropping it can visibly shift the image - flat skin tones, dull sunsets - on any screen that is not plain sRGB. That is kept, along with the format headers. What comes out is EXIF, GPS, XMP, IPTC, comment blocks and text chunks: everything describing you, your device, your location or your workflow.
When you want to keep EXIF
Metadata is not the enemy - it is only a problem when it leaves with the photo, so keep your originals intact and strip copies on the way out. Photo libraries sort and map by EXIF, so wiping an archive scatters it across the wrong dates. IPTC credit fields exist so authorship survives a repost. And for documentation, the timestamps are the point.
Worth knowing too: if you have already run a photo through the Image Resizer, Image Compressor, Crop Image or Image Converter, the output has no metadata already. Those all redraw the picture onto a canvas, and a canvas has no memory of the tags on the file that fed it. The trade-off is that redrawing a JPG re-encodes it - exactly the quality cost the dedicated tool avoids.
Clean your photos now
It is a ten-second job, once per file: load the photo, read what it says about you, download the clean copy, send that one instead. Open the EXIF Viewer & Remover - free, no sign-up, no watermark, and the photo never leaves your browser, which for a tool whose whole purpose is privacy is rather the point.
Frequently asked questions
- Does removing EXIF data change how the photo looks?
- No. The metadata sits in its own labelled blocks inside the file, entirely separate from the compressed image data, so removing it means rewriting the container without those blocks and copying the picture across byte for byte. Nothing is decoded and nothing is re-compressed, which is the important difference from clearing metadata by opening the photo in an editor and saving a copy - that re-runs JPG compression and softens the image slightly every time. The colour profile is deliberately kept, so colours render exactly as before. The only visible change is a smaller file.
- Do social media sites already remove EXIF data for me?
- Usually, but do not rely on it as your only protection. Large platforms tend to re-encode uploads and drop metadata as a side effect, so the copy other users can download is generally clean - but the platform itself still received the original, the behaviour is theirs to change, and it covers only that one route. Email attachments, cloud share links, marketplace listings and chat apps that send a photo as a file or document all pass the original through untouched. Stripping the metadata before the file leaves your device makes the question moot.
- Can EXIF data be recovered from a photo after it has been removed?
- Not from the cleaned file. The bytes that held the metadata are not blanked or hidden, they are simply not written into the new file, so there is nothing left in it to recover. Two things are worth remembering, though. Your original is untouched on your disk, since the clean version downloads as a separate copy - so make sure you send the right one. And if the photo has already been shared, any copy that went out before still carries everything it always did.
