Image EXIF & Metadata

What is EXIF metadata?#

EXIF (Exchangeable Image File Format) is the block of metadata tucked into JPEG, TIFF and some WebP files by the camera or editor that produced them. A typical phone photo carries the camera make and model, lens, focal length, aperture, exposure time, ISO, the date and time the shot was taken, orientation, colour space — and, often, the GPS coordinates of where it was taken. This page reads all of it, sorts it into sensible groups, and (for JPEG) lets you edit or strip it before re-sharing.

Two abilities make this tool more than a viewer. First, GPS coordinates are parsed from the camera’s degrees/minutes/seconds form into decimal degrees and offered as a clickable map link — so a photo taken at 48°51'31"N, 2°17'39"E resolves to a precise pin. Second, for JPEG files you can strip GPS only, strip everything, or set the artist, copyright and comment tags, then download a cleaned copy. That matters because raw phone photos routinely leak home addresses and exact timestamps the moment they are uploaded unmodified.

Editing is gated to JPEG because the underlying writer (piexifjs) is JPEG-only; PNG, WebP and other formats are read-only here.

How to use it#

1. Drop an image onto the dashed zone. A preview appears, followed by grouped metadata tables.
2. Read the groups: Camera (make, model, lens, focal length, aperture, exposure, ISO), Exposure (program, metering, white balance, flash), Date (original, digitised), GPS (latitude, longitude, altitude, with a map link), Image (dimensions, orientation, colour space, software) and Other.
3. For JPEG files, the edit panel opens. You can:
   • Type an Artist, Copyright or Comment to stamp onto the file.
   • Click Strip GPS to remove only location data.
   • Click Strip all to remove every EXIF tag.
   • Click Apply & download to save the cleaned JPEG.
4. For non-JPEG files, an “edit is JPEG-only” notice appears instead.

Key features#

• Grouped, labelled output. Raw EXIF keys (FNumber, ExposureTime, GPSLatitude) are mapped to readable labels and sorted into six stable groups instead of an alphabet soup.
• Friendly units. Exposure 0.005 becomes 1/200 s; aperture reads f/1.6; GPS degrees/minutes/seconds become decimal degrees with a map link.
• GPS strip for privacy. One click removes the location block — the single most sensitive field in a shared photo.
• Full strip plus copyright stamp. Add your attribution while removing everything else, ready for public sharing.
• Local only. exifr and piexifjs run in the browser; your photos are never uploaded.

Worked example#

Drop a JPEG straight from a phone camera. The Camera group reports Make: Apple, Model: iPhone 15 Pro, Focal length: 6.86 mm, F-Number: f/1.78, Exposure: 1/120 s, ISO: 64. The GPS group shows Latitude: 48.8588, Longitude: 2.2944 with a map link that resolves to a spot in Paris.

Before posting that photo publicly, click Strip GPS, then Apply & download. The downloaded JPEG is byte-for-byte the same image, but the GPS block is gone — the GPS group now reads empty, and the home-address leak is closed while the visible photo is untouched.

FAQ#

Why can’t I edit EXIF on my PNG or WebP?#

The writer this page uses (piexifjs) speaks EXIF in JPEG’s APP1 segment only. PNG and WebP store metadata differently, so for those formats this tool is read-only — you can still view everything, just not edit or strip it.

Does stripping GPS really remove the location?#

Yes. Strip GPS rewrites the JPEG’s APP1 segment with the GPS IFD deleted, then hands you a fresh file. There is no residual location data in the output. To be certain, re-drop the downloaded file and confirm the GPS group is empty.

The GPS pin is a few metres off — why?#

Consumer GPS accuracy is roughly 3–10 metres on a clear day, and the stored coordinate is rounded to four decimal places (about 11 metres). The position you see is as good as the phone recorded; the tool does not smooth or correct it.

Can I batch-strip a folder of photos?#

Not here — this page processes one file at a time, by design, so nothing is ever queued or uploaded. For bulk workflows, a command-line tool is the right fit; this page is for the occasional single photo you want to share safely.
