Free EXIF editor.

EXIF (Exchangeable Image File Format) is the block of metadata that cameras and phones embed inside every JPEG: when the photo was taken, where (GPS), with what camera and lens, at what aperture, shutter speed, and ISO. An EXIF editor lets you change those values without re-taking the shot. Common reasons: correcting a wrong camera clock, removing a GPS pin before sharing, attributing a photo to a different studio, fixing a typo in the copyright line, or adding context for archive purposes.

Four grouped sections: Camera (make, model, software, lens model, f-number, exposure time, ISO, focal length), Date & time (date taken, date digitised, modify date), GPS (latitude, longitude, altitude in decimal degrees and metres), and Author (artist, copyright, image description, user comment). Each field has a reset button that returns it to the original value. Untouched fields are preserved exactly as they were.

Yes. No accounts, no daily caps, no per-file size limit, no watermark. Everything runs in your browser using the piexif.js library. We never see your photo.

EXIF as a standard is most reliably round-tripped inside JPEG. PNG, WebP, and HEIC can carry metadata but the encoders shipped with browsers don't write it back consistently. If you have a HEIC photo, convert it to JPEG first with our HEIC tool, then edit. PNG files have no EXIF block in the traditional sense; their metadata uses iTXt and tEXt chunks that aren't part of this editor.

Decimal degrees. San Francisco is 37.7749, -122.4194 (positive latitude = north, negative = south; positive longitude = east, negative = west). The tool converts to the standard EXIF degrees-minutes-seconds rational format automatically. To wipe GPS entirely, clear both lat and lng fields then save; the GPS block will be removed.

Exposure time accepts both '1/250' (preferred) and '0.004' (decimal seconds). Aperture (f-number) accepts '2.8', 'f/2.8', or 'F2.8'. ISO is a whole number. Focal length is in millimetres (e.g. '50' for a 50 mm lens).

It will update DateTimeOriginal and DateTimeDigitized (what most apps read for 'when was this taken'). If the file system's modification date matters to your app, you may also need to set the file mtime separately (browsers cannot do this from the download dialog). For photo libraries that index by EXIF (Apple Photos, Adobe Lightroom, Google Photos), the new date is picked up on re-import.

Yes. The 'Strip all metadata' button removes every EXIF tag and exports a clean JPEG. Use that for sharing photos on social media where you don't want any trace of GPS, camera, or capture date. Our dedicated EXIF Remover tool has more granular options (keep date but remove GPS, for example).

No. We insert the new EXIF block into the existing JPEG byte stream without re-encoding the pixels. Image quality is identical to the source; only the metadata changes.

Many EXIF tags are not commonly user-edited (chromatic aberration, MakerNote, sub-IFDs from camera firmware). Those are preserved untouched. If you need to edit a niche tag, our companion 'EXIF Tag Reference' guide lists every tag and what it means; for true power-user editing, the open-source ExifTool command-line tool is the gold standard.
