EXIF-megjelenítő és -eltávolító

See everything your photo says about you

Every photo from a camera or phone carries hidden EXIF metadata: the camera and lens, the exposure settings, the exact second it was taken — and, very often, the precise GPS coordinates of where you stood. This free EXIF viewer reads it all in your browser: drop a JPG or PNG and get summary cards for camera, date, exposure and location, plus the full metadata table with copy-all.

If the photo contains GPS tags, a prominent warning appears with a map link — so before you share a file, you know exactly what it would reveal. The parsing runs locally in JavaScript; the photo is never uploaded to any server. Compare that to Jimpl, Verexif and Metadata2Go, which all upload your image before they can show you its data.

Remove metadata losslessly — pixels untouched

One click on Remove metadata downloads a cleaned copy with the EXIF, GPS, editing-history and comment blocks gone. Crucially, this tool strips metadata the lossless way: it removes the metadata segments from the file structure without re-encoding the image, so the pixels in the cleaned file are byte-identical to the original. Zero quality loss — unlike many online removers that quietly recompress your photo.

The cleaned file is usually smaller too (embedded thumbnails and maker notes add real weight), and the tool reports the exact savings. Your original file is never modified — you always get a new '-clean' copy to download.

Why photo metadata is a privacy issue

GPS tags can map your home, workplace and travel patterns; timestamps and device details narrow down who took a picture and when. Anyone who receives an original file — by email, cloud link, or WhatsApp's 'send as document' mode — can read all of it with any free viewer.

Social platforms strip EXIF before display (Instagram, Facebook, X), but they read and keep the data server-side first. Many sharing channels don't strip anything at all: email attachments, cloud drives, classified-ad uploads, forum posts. The safe habit: strip metadata before the file leaves your device — which is precisely what this tool does, on your device.

For photographers: read the settings behind any shot

EXIF is also the photographer's notebook. Load a shot and the exposure summary shows the shutter speed, aperture, ISO and focal length that produced it, alongside the camera body and lens model — perfect for learning from your best frames, documenting gear for a sale, or answering 'what settings did you use?' on a forum.

The full table includes orientation, resolution, white balance, flash mode, software and timestamps, and 'Copy all' exports everything as text. Pair it with the GPS map link to organize shoots by location — or strip the location before posting while keeping your camera info intact for the photo community.

How this compares to Jimpl, Verexif and Metadata2Go

Jimpl is probably the most-used online EXIF viewer, but it uploads your photo to its servers and keeps files for up to 24 hours. Verexif and Metadata2Go both process images server-side too. For a task that's literally about privacy and location data, uploading to a third-party server is a strange trade.

This tool does everything in your browser. Load DevTools' Network tab and drop a photo — you'll see zero upload requests. It also works offline once the page has loaded, handles both JPG and PNG, and strips metadata without re-encoding pixels. Free, no account needed, and nothing leaves your device.

The full EXIF tag catalog: what's actually inside a photo

The EXIF standard defines hundreds of tags, and a single smartphone photo can carry 50 or more of them. The most important fall into three groups. Camera identity: make (Canon, Nikon, Apple, Samsung), model (iPhone 15 Pro, Sony A7 IV), lens model, and camera serial number on some bodies. Exposure settings: shutter speed (expressed as a fraction, e.g. 1/250 s), aperture (the f-number — f/1.8, f/8), ISO sensitivity, focal length in millimetres, focal length equivalent in 35 mm terms, flash fired and flash mode, exposure compensation, exposure program (Manual, Aperture Priority, Auto), metering mode, and white balance (Auto or a named preset like Cloudy).

Image geometry and quality tags include pixel width and height, horizontal and vertical resolution in DPI, color space (sRGB or AdobeRGB), and the orientation flag — a value from 1 to 8 that tells software whether to rotate or mirror the image on display, which is the source of the infamous 'uploaded sideways' problem when apps ignore it. There are also time and authorship tags: DateTimeOriginal (when the shutter fired), DateTimeDigitized (when a film scan was made digital), DateTime (last modified), software used to edit the file, artist name, and a copyright string. Professional shooters and stock photo agencies rely on those last two to assert ownership the moment a file is created.

GPS tags form their own sub-directory within EXIF: GPSLatitude and GPSLatitudeRef (N/S), GPSLongitude and GPSLongitudeRef (E/W), GPSAltitude and GPSAltitudeRef (above or below sea level), GPSSpeed, GPSImgDirection (compass bearing the camera was pointing), and GPSDateStamp. A phone records all of these in the fraction of a second it takes to write a photo to storage — which is why an original JPEG from a smartphone is, without stripping, a precise record of where you were, when, and which direction you were facing.

GPS data and the real privacy risk of unstripped photos

The danger of EXIF GPS tags is not theoretical. In 2012, journalist colleagues following John McAfee discovered his location in Guatemala after Vice published a photo taken on an iPhone — the article's embedded image retained GPS coordinates that pointed to within metres of his hiding spot. The coordinates were visible to anyone with a free EXIF viewer. Earlier cases pre-date smartphones: the 2006 murder of Maura Murray and several investigations involving paparazzi shots demonstrated that even consumer digital cameras with optional GPS units embed precise location data that survives email forwarding and web upload when no stripping step is applied.

The platform landscape is uneven. Instagram strips GPS and most EXIF before delivering photos to other users, though it processes the original on its servers first. Facebook does the same. Twitter/X did not strip EXIF from uploaded images until mid-2022 — years of original uploads carried full GPS data readable by anyone who downloaded the file. iCloud Shared Albums strip location. WhatsApp strips EXIF from normally-sent images but preserves it entirely when you send a photo 'as a document.' Email attachments, cloud drive share links, classified-ad uploads, and direct file transfers via AirDrop or Bluetooth preserve everything.

The practical rule: never share an original photo file without checking its metadata first — especially if you took it on a phone with location services enabled. Strip the GPS block, or strip all metadata, before the file leaves your device. This viewer flags GPS presence prominently and removes it in one click, entirely in your browser, without the file ever touching a server.

EXIF in legal and forensic contexts

Courts and forensic investigators treat EXIF metadata as potential evidence, but it must be interpreted carefully. DateTimeOriginal is written by the camera's internal clock and can establish when a shutter fired — useful in alibi disputes or for sequencing events. Combined with GPS coordinates, a photo can place a specific device (and by inference, its owner) at a precise location at a precise moment. That combination has been used in criminal prosecutions, civil litigation over construction defect timelines, and insurance fraud investigations where claimants' own photos undermined their stated facts.

Forensic examiners also use EXIF to detect tampered images. Inconsistencies are a red flag: a photo that claims to be from a Canon EOS R5 but lacks the MakerNote block that every R5 writes is suspicious. A file whose EXIF DateTimeOriginal is weeks before the file system creation timestamp may have been backdated. Missing or inconsistent GPS accuracy fields, unexpected software tags (showing a photo passed through editing software despite claims it is unedited), or EXIF fields whose values are impossible for the claimed camera model all warrant scrutiny.

The counter-point is that EXIF is not authenticated data. ExifTool and dozens of other programs can write or overwrite any tag in seconds. A forensic examiner who presents EXIF alone as proof is on weak ground — they need to pair it with file-system metadata, hash comparisons, and where possible device extraction to make a robust case. For the same reason, a defence argument that EXIF was manipulated is always available. The metadata is evidence, not proof — it raises or lowers probability rather than settling facts on its own.

EXIF vs. IPTC vs. XMP: three metadata systems inside one file

EXIF (Exchangeable Image File Format) was defined by JEIDA in 1995 and is written by the camera or phone at capture time. It is binary, structured, and optimised for technical camera data. EXIF lives in the APP1 marker segment of a JPEG and is the data this viewer reads and strips. IPTC (International Press Telecommunications Council) metadata predates EXIF — it began as a wire-service standard for captioning news photos in the 1990s. Its fields include caption/abstract, credit line, by-line (author), copyright notice, city, country, keywords, and category codes. When a photo editor adds a caption and rights statement in Adobe Lightroom's Metadata panel, they are writing IPTC fields. These travel inside the JPEG's APP13 marker and survive independently of EXIF.

XMP (Extensible Metadata Platform) is Adobe's XML-based standard, introduced in 2001. It is designed to be human-readable, extensible, and able to wrap and extend both EXIF and IPTC fields within a single RDF/XML block — embedded in JPEG, TIFF, PNG, PDF, and many other formats. When Lightroom records an edit history, star rating, colour label, face tags, or develop settings, it writes XMP. The same data can be stored in a sidecar .xmp file alongside a raw (CR3, NEF, ARW) file rather than inside the image itself.

In practice all three coexist inside a single JPEG: EXIF holds the technical capture data, IPTC holds caption and rights, XMP holds edit history and any fields the other two cannot express. Tools vary in which layers they read and write: most EXIF viewers show only the EXIF block; Lightroom writes all three; ExifTool by Phil Harvey — the definitive open-source command-line tool for metadata manipulation — can read, write, copy, and delete every tag in every standard. For professional publishing workflows, embedding IPTC copyright and contact information at the point of capture (via camera firmware or Lightroom's metadata presets) is the standard way to assert ownership in every file that leaves your archive, because it survives through editing and format conversion in a way that a watermark does not.
