EXIF editing
EXIF Editor
Click any field in a photo's metadata and type a new value. This EXIF editor lets you fix a date, shift every timestamp in a file by an hour when a camera's clock was wrong, set or remove GPS, and add fields that weren't there before, then download an edited copy. It all runs in your browser, so the photo you're editing never leaves your device.
Shifting dates is the fix people ask for most, and it doubles as an exif date changer for anyone whose camera clock drifted or was never set after a battery swap: give the shift-all control an hour and minute offset and every date field in the file moves together, so a whole shoot's timestamps line up with real time in one action instead of one field at a time.
As a photo exif editor it goes past dates. Set, change or clear GPS coordinates, fill in artist and copyright, or add a field that wasn't in the file at all: PNG accepts any key you like, JPEG and WebP offer a picker of the standard writable tags. A few fields stay locked, maker notes and the ICC colour profile among them, because rewriting them incorrectly can corrupt a file or shift its colours, and a padlock icon says so rather than pretending to support something that would risk your photo.
Some editors handle saves by re-encoding the whole image; imgi rebuilds only the metadata segment, so a trip back through the EXIF and metadata viewer after saving shows the pixels unchanged. Want to remove data instead of changing it? Remove metadata from a photo does that in one click, and Where was this photo taken reads back the GPS you just set.
What you can edit, field by field
Press Edit and the report's tables turn into inputs. Most of what a camera writes is fair game; a handful of fields stay locked on purpose, and the table below says which is which.
| Field | Editable? | Notes |
|---|---|---|
| DateTimeOriginal & friends | Yes | Type a value, use the picker, or shift every date field at once. |
| GPSLatitude / GPSLongitude | Yes | Set, change, or remove the location entirely. |
| Artist / Copyright / ImageDescription / UserComment | Yes | Plain text fields, editable or addable from scratch. |
| Software / Orientation | Yes | Standard writable EXIF tags. |
| MakerNote | Locked | Opaque proprietary bytes; rewriting it wrong can make a file unreadable. |
| ICC colour profile | Locked | Controls colour display; edited wrong, colours shift. |
| Thumbnail (IFD1) & Image/file group | Locked | Camera-generated or structural, not metadata you'd hand-edit. |
Fixing a camera clock that's off
A camera that's never had its date and time set, or whose battery died and reset the clock, stamps every photo with a time that's wrong by a fixed amount, sometimes a few hours off from a timezone crossing, sometimes reset to a factory default years in the past. Retyping the correct date into a hundred files one at a time is nobody's idea of a productive afternoon. Shift-all fixes the actual case: open one photo, tell the editor the offset, say minus three hours, and every date field inside that file moves by exactly that amount in a single action. It is scoped to one file today; a folder-wide version is the natural next step once single-file editing has proven out.
If a value inside a locked field, or an existing XMP entry, can't be safely located and rewritten, the field shows as locked instead of being changed and possibly getting it wrong. Every edited file is re-parsed after saving to confirm it still opens and the new values read back correctly.
Adding a field that wasn't there
Not every field exists in every file, and the editor lets you add ones that don't. PNG metadata is just free-form text chunks, so you can type any key and value you like: a caption, a project name, anything. JPEG and WebP store metadata as structured EXIF tags instead, so new fields there come from a picker of the standard writable ones (strings, dates, GPS, orientation, Artist, Copyright, ImageDescription, UserComment) rather than an arbitrary key, because an unrecognised tag id isn't something most other software would ever read back. A custom key with no matching EXIF tag gets written into an XMP packet instead, which the file gets if it doesn't already have one.
Common questions
01Can you change the date a photo was taken?+
Yes. Press Edit, click the date field, and type a new value or pick one from the date picker. If every date in the file is off by the same amount, for example because a camera’s clock was never set after a battery change, use the shift-all-dates control instead: give it an hour and minute offset and it applies to every date field in the file at once, rather than making you retype each one by hand.
02Does editing EXIF reduce image quality?+
Not here. Editing only rewrites the metadata segment, the small block that holds EXIF, GPS and similar fields. The picture data sits in a completely separate part of the file and imgi never touches it, so the edited photo is pixel for pixel identical to the original, just with different metadata. Some editors redraw the whole image to write changes back, which quietly re-compresses it; this one does not.
03Can you fix a wrong camera clock across a batch of photos?+
Not yet, and it would be dishonest to say otherwise. Today the editor works on one photo at a time: open a file, use shift-all-dates to correct every date field inside it in a single move, then download the edited copy. If a whole folder from the same trip has the same clock error, you’ll need to repeat that per photo for now.
04Can you add GPS location to a photo?+
Yes. If a photo has no GPS field at all, Edit lets you type in a latitude and longitude and the tool writes a new GPS block into the file. If it already has coordinates, you can change them the same way, or remove them entirely with one click if you’d rather the photo carried no location at all.
05Is my photo uploaded to edit it?+
No. Reading, editing and rebuilding the file all happen in your browser with JavaScript. Nothing about the image is sent anywhere while you work on it; you only get a file again when you press download, and that download comes straight from your own device, not a server.
06Which fields can be edited, and which are locked?+
Most fields you’d actually want to change are editable: dates, GPS, camera and lens strings, artist, copyright, description and similar text fields. A few stay locked behind a small padlock: MakerNote, because it’s an opaque block of proprietary bytes a camera maker defines, and rewriting it wrong can make a file unreadable to some software; the ICC colour profile, because it controls how colours are displayed and editing it risks shifting the picture’s colours; and the embedded thumbnail, which the camera generates itself and isn’t something you’d hand-edit anyway.
