About the EXIF Editor
Correct the metadata of your own JPEG photos without touching the picture: set the date and time taken, or shift a whole batch when the camera clock was wrong or still on home time after a trip; record the time zone; write your name, copyright and a description; fix the orientation tag; and add, change or remove the GPS location.
The editor changes only the metadata block. The compressed image data is copied byte for byte (and checked after every edit), and the rest of the EXIF data — camera settings, maker notes, thumbnail — stays where it is, so camera software can still read it. Edit one photo or hundreds at once and download them as a ZIP. Everything happens in your browser; photos are never uploaded.
How to use it
- Choose, drop or paste one or more JPEG photos. Each one shows its current date taken, camera, location and orientation.
- Pick the changes. To fix a camera clock, choose Shift and enter the difference — or let the tool work it out from one photo whose real time you know (for example a photo of a clock or a timestamped receipt).
- Set the time zone if your photos need it, fill in artist, copyright or description, and choose a location or Remove to delete it.
- Select Apply and download. One photo downloads as a JPEG; several download together as a ZIP. The list shows exactly what changed in each file.
Examples
Taken 2026-03-14 04:56:53 (camera on UTC+00:00) · Shift +5 h 30 min · Time zone +05:30
Date taken 2026-03-14 10:26:53, time zone UTC+05:30 — on every selected photo
A photo of a station clock showing 18:42:10 has date taken 2026-01-03 17:40:55
Shift +1 h 1 min 15 s, applied to all photos from that camera
24 scans without dates · Set 1998-06-01 12:00:00 · Gap 60 s
In file-name order: 12:00:00, 12:01:00, 12:02:00… so albums sort the scans in the right order
Phone photo with GPS 18.520400° N, 73.856700° E · Location: Remove
GPS block deleted (its bytes are overwritten, not just unlinked); XMP location removed too
Which fields are changed
- Date taken is Exif
DateTimeOriginal, date digitised isDateTimeDigitizedand date modified isDateTime, all in the formatYYYY:MM:DD HH:MM:SSlocal time. Choose which of the three to change. - Time zone goes into
OffsetTimeOriginal,OffsetTimeDigitizedandOffsetTimeas+05:30. These tags exist since Exif 2.31, so an older file’s Exif version is raised to 0231 when they are added. GPS time stamps are recorded in UTC by the receiver and are left alone. - Artist, Copyright and Description are the IFD0 tags
Artist,CopyrightandImageDescription. - Orientation is the tag that tells viewers how to turn the stored picture (CIPA DC-008-2024, values 1–8). Rotating here changes only that tag, never the pixels, so it is lossless.
- Location is the GPS block: latitude and longitude as degrees, minutes and seconds (to 1/10,000 of a second, about 3 mm), and the altitude in metres above or below sea level, with GPS version 2.3.0.0, whose altitude reference is sea level.
- If editing apps have written XMP dates (such as
xmp:CreateDateorphotoshop:DateCreated), they are shifted or set together with the matching Exif date, and XMP location properties are removed with the GPS block.
Definitions: CIPA DC-008-2024, Exif 3.0 (CIPA standards).
How the photo stays intact
A JPEG keeps its metadata in segments in front of the compressed picture. This editor rewrites only the EXIF segment (and the XMP segment when XMP dates or locations change) and copies everything from the start of the picture data unchanged; after each edit it compares that data with the original and reports the result.
Inside the EXIF block, existing data never moves: a changed directory is written again at the end of the block and pointed to (or, when the block is nearly full, over its own old copy), so maker notes — the camera maker’s private data, whose internal offsets often break when other editors rearrange a file — the thumbnail and every other tag keep their positions. The bytes of replaced or removed values, such as an old GPS position, are overwritten with zeros, so they are really gone.
Edited metadata is not evidence
Anyone can change EXIF data — with this tool or many others — and the changes leave no trace in the file. A date or location in a photo’s metadata therefore proves nothing about when or where it was taken, and it should never be used to make a photo look like something it is not. Use this editor to fix and credit your own photos.
Limitations
- JPEG only. HEIC, PNG, WebP, TIFF and RAW files are not edited (convert HEIC photos with the HEIC to JPG converter first).
- Text with characters beyond plain ASCII (such as ©, é or Devanagari) is stored as UTF-8 in the classic ASCII text tags. Exif 3.0 defines a separate UTF-8 type, but readers such as exifr reject that type, while they read UTF-8 in the classic tags correctly. Very old programs may show such characters garbled; plain ASCII, for example “(c)”, is the most compatible.
- XMP creator, rights and description (written by editing apps such as Lightroom) and the Windows File Explorer tags XPAuthor, XPTitle, XPSubject and XPComment are not changed; the tool tells you when you edit a field and a photo has one of them. Place names in IPTC or XMP are kept when the GPS location is removed.
- An XMP date that has no time of day is not shifted. Extended XMP (used for depth maps and panoramas) is not touched.
- The EXIF block of a JPEG can hold at most 64 KB; very long descriptions are refused rather than cut off. When a photo’s block is already nearly full (for example because of a large thumbnail), new dates, orientations, locations and shorter texts are written over the old values instead, but adding tags it does not have yet, such as a time zone, may not fit — the tool then says so and leaves the file unchanged.
- Up to 300 photos of up to 60 MB each per batch, and about 1 GB in total (2 GB on computers with 8 GB of memory or more), because the edited copies and the ZIP are made in your browser’s memory. Edit larger collections in several batches.

Frequently asked questions
Does editing EXIF reduce the quality of my photo?
No. Only the metadata segments are rewritten; the compressed picture data is copied byte for byte, and the tool checks that after every edit. The file size changes only by the size of the new metadata.
How do I fix photos taken with the wrong camera time?
Choose Shift. If you know how far off the clock was, enter the difference. Otherwise pick one photo whose real time you know — a photo of a clock, a phone screen or a timestamped ticket works well — enter its correct date and time, and select Use this difference. Apply the shift to all photos from that camera.
What does the time zone setting do?
It records the photo’s UTC offset (for example +05:30) in the Exif offset tags, so apps can place the photo correctly on a timeline. It does not move the time itself — combine it with a shift if the clock was on another zone.
Will Google Photos or Apple Photos show the new date?
Such apps read the date taken when a file is added to the library, so add the edited copy. A photo that is already in a library keeps the date stored there; Google Photos and Apple Photos also let you change the date inside the app.
Does removing the GPS data really delete it?
Yes. The GPS directory and all of its values are overwritten with zeros, and XMP location properties are removed. Place names in IPTC/XMP and anything visible in the picture itself are not changed. To remove all metadata at once, use the Image Metadata Viewer’s clean copy.
Are my photos uploaded?
No. The photos are read and edited by your browser, on your device, and the edited copies are saved straight to your downloads. The originals on your device are not changed.
