RAW EXIF viewer: free, in your browser, nothing uploaded
Drop any photo below to read its full EXIF metadata: camera, lens, exposure settings, capture date, GPS and the complete tag table. It reads RAW files directly: Sony .ARW, Canon .CR3 and .CR2, Nikon .NEF, Fujifilm .RAF, Olympus .ORF, Panasonic .RW2 and .DNG, plus JPEG, HEIC, PNG, WebP and TIFF. JavaScript parses everything on your own machine: a 60 MB RAW opens instantly because there is no upload, and your photograph never leaves your computer.

Everything runs in your browser. Nothing leaves your machine.
No upload button, by design
Most online EXIF viewers work by uploading your photograph to their server. For a phone snapshot that is slow; for a 40–100 MB RAW it is painful. Either way, your file is now on someone else's machine. This viewer takes the opposite approach: the page hands your file to JavaScript running locally, which reads the metadata bytes and renders them. You can switch off Wi-Fi after the page loads and it keeps working. It is the same principle behind RevelRaw itself, a native macOS RAW editor where decoding, AI scene detection, editing and export all happen on your Mac: no cloud, no account, no tracking.
Format coverage
| Format | Where the metadata lives | Guide |
|---|---|---|
| .ARW .SR2 | Standard TIFF structure, read directly, including lens model and Sony's compression variant | Sony ARW |
| .CR3 | Canon's modern video-style container; EXIF lives in Canon-specific records this viewer unpacks | Canon CR3 |
| .CR2 | Standard TIFF structure, read directly | Canon CR2 |
| .NEF .NRW | Standard TIFF structure, read directly | Nikon NEF |
| .RAF | Fujifilm's own header wrapping an embedded JPEG; the viewer reads the EXIF from there | Fujifilm RAF |
| .ORF | TIFF structure behind an Olympus signature | Olympus ORF |
| .RW2 | TIFF structure behind a Panasonic signature, plus Panasonic's own sensor tags | Panasonic RW2 |
| .DNG .TIFF | Standard TIFF structure, read directly | All formats |
| .CRW | Canon's pre-2004 CIFF container; no EXIF block exists to read | Canon CRW |
| JPEG · HEIC · PNG · WebP | EXIF segment or chunk in each container | — |
For RAW files the viewer also pulls out the embedded JPEG preview the camera hides inside the file, so you see the photograph next to its data, even for formats your browser cannot display.
Reading the numbers like a photographer
A few of the fields repay a closer look. Exposure is the familiar triangle of shutter speed, aperture and ISO, plus exposure compensation if you dialed any in. Lens tells you which lens you had mounted, and on crop-sensor bodies the 35 mm-equivalent focal length puts the framing in full-frame terms. Software reveals whether a file came straight off the card or passed through an editor. And GPS deserves attention before you share an original file: if location was on, the camera embedded your exact shooting position, and anyone with a viewer like this one can read it. The tool flags it when present.
The viewer leaves the maker note undecoded: the proprietary block where brands hide focus data, in-camera looks (Canon Picture Styles, Fujifilm Film Simulations, Sony Creative Looks) and service counters. It tells you when one is present. Those in-camera looks live in the metadata, and the pixels stay untouched, which is why a RAW opened in an editor looks flatter than the camera JPEG. Our format guides cover what sits inside an ARW, a CR3 or a NEF.
FAQ
How do I use this EXIF viewer?
Open revelraw.com/exif-viewer in any browser and drag your photo onto the drop zone, or click it to choose a file. The viewer reads the file on your machine and shows the camera, lens, exposure, capture date, GPS and the full tag table; for RAW files it also extracts the embedded JPEG preview. There is no account, no install and no upload, and once the page has loaded it works offline.
Is my photo uploaded when I use this EXIF viewer?
No. JavaScript running in your browser reads and parses the file on your own machine. Nothing goes over the network: you can load this page, disconnect from the internet, and the viewer keeps working.
Which file formats does the viewer read?
RAW formats: Sony .ARW and .SR2, Canon .CR3 and .CR2, Nikon .NEF and .NRW, Fujifilm .RAF, Olympus and OM System .ORF, Panasonic .RW2, and .DNG. Standard formats: JPEG, HEIC, PNG, WebP and TIFF. The viewer detects Canon's pre-2004 CRW, but the format has no EXIF block to read.
Why does my photo show no lens, GPS or even no metadata at all?
Cameras write GPS only when you switch location on (or the photo came from a phone), and manual or adapted lenses report little or no lens data. If a photo shows no metadata at all, something stripped it along the way: social networks, messaging apps and many export settings remove EXIF on upload or save.
Can this tool remove EXIF data from a photo?
No, it is read-only by design. To control what metadata ships with a photo, decide at export: most editors let you strip everything or write the fields you choose. RevelRaw, for example, embeds author, copyright, Creative Commons license, caption, keywords and GPS via standard EXIF and IPTC fields on export, or none of it.
What is a maker note?
A proprietary block inside the EXIF where each brand stores camera-specific settings: focus mode and AF points, in-camera looks, shutter count and more. No brand documents the layout, and each one differs. This viewer tells you when one is present and shows the standard EXIF set.
Does it read iPhone HEIC photos?
Yes. HEIC files carry regular EXIF inside an ISO media container, and the viewer reads it: camera model, lens, exposure and, if location was on, GPS coordinates.
