Batch EXIF editor — view, edit and remove EXIF data in your browser

Field guide

Which EXIF fields are safe to edit?

Authorship fields — image description, artist, copyright and software — are plain ASCII strings. Changing them affects nothing but the text that photo viewers display, so they are the safest fields to edit. Dates are almost as safe, with one caveat: the EXIF date format is fixed (YYYY:MM:DD HH:MM:SS, colons included), and some readers silently ignore a value that does not match it exactly. This editor validates the format before writing anything.

GPS fields deserve more care. Latitude and longitude are stored as degrees, minutes and seconds with N/S/E/W reference letters — the tool converts your signed decimal degrees for you — and a mistyped coordinate can move your photo to the wrong ocean. When in doubt, tick "clear GPS": removing the location is the common case, and it is what "remove GPS from photos" should actually mean — no location tags left at all, not just rounded ones.

Fields this editor deliberately does not offer — camera serial numbers, MakerNote blobs, lens identifiers — are dropped entirely when you save, so there is nothing left to manage.

Under the hood

Why rewriting beats patching

Most EXIF editors patch the existing block in place: they overwrite a value here, shift an offset there, and hope every dangling reference still lines up. Two problems follow. First, the old data area survives — orphaned strings, stale thumbnails and vendor-specific blobs stay inside the file even after their pointers are gone. Second, a single miscounted offset corrupts the whole block, and some readers then refuse the file.

This EXIF editor takes the stricter route. On save it builds a brand-new TIFF structure containing only the fields in the form, computes every offset from zero, and swaps the old APP1 segment for the new one. The output is small, deterministic and easy to verify — which is why the tool re-scans the result in front of you before offering the download.

The trade-off is stated honestly: camera settings like ISO and aperture are discarded along with the serial numbers. If you need those kept, do not save an edit — keep the original. If you need them gone everywhere, that is what the strip modes are for.

Picking the right move

Edit, strip, or reset the image fingerprint?

Editing is for accuracy: fixing a wrong capture date, adding an artist name, attaching a copyright line before publication. Stripping is for sharing: the single-image button and the batch EXIF remover in step 3 both re-encode the picture with zero metadata left behind, and the post-clean scan proves it.

Neither one changes the pixels. If copies of an image have already circulated, platforms can still match them by hashing the pixel data itself — the image fingerprint. The main MetadataRemover cleaner adds an invisible ±1–2 RGB perturbation that breaks that match. Use this editor to control what a file says; use the main cleaner when you also need it to stop looking like itself.
