How to Edit EXIF Data (Change Date, GPS, Camera)

Quick answer: Yes, you can edit EXIF data in your browser for free. Drop a photo into our EXIF Editor and change the fields that are wrong: DateTimeOriginal (the capture date), GPS coordinates, camera Make and Model, and copyright or author. The tool writes your changes back into the file and you download the corrected version. Nothing uploads, nothing installs, and the rest of the metadata stays untouched.

EXIF is the hidden metadata block every photo carries (the full picture is in what is EXIF data). Most of the time you just read it, but sometimes a field is wrong and you need to fix it. This guide covers when editing EXIF is the right move, which fields people change most, and exactly how to do it in your browser.

Why edit EXIF data

A few common reasons the metadata is wrong and worth correcting:

• The capture date is wrong. The camera clock was never set, or it was set to the wrong time zone, so every photo from that trip is off by hours or days. Fixing DateTimeOriginal puts the photos back in the right order.
• You want attribution on your work. Add your name to Artist and a copyright string to Copyright so the credit travels with the photo when it gets republished.
• GPS is missing or wrong. Location Services was off when you shot, so you can back-fill the correct location by pasting in latitude and longitude.
• You are normalizing before an import. Lightroom and Google Photos sort by DateTimeOriginal, so cleaning up dates first means the library groups everything by the correct day instead of by file-write time.

This is editing, not removal. If your goal is privacy (stripping GPS and metadata before you share), that is a different job covered in how to remove EXIF data on iPhone. Editing changes a value; removal wipes it.

How to edit EXIF in your browser

Our EXIF Editor edits individual fields and writes them back into the file. Here is the workflow:

1. Open the EXIF Editor.
2. Drop your photo onto the page. The editor reads the existing EXIF and shows each field in an editable form.
3. Change the fields you need. Type a new date into DateTimeOriginal, paste coordinates into the GPS fields, or fill in Make, Model, Artist, and Copyright.
4. Hit Download. The tool inserts your changes and leaves every untouched tag byte-for-byte identical.

Two things make this clean. Nothing uploads: the file is parsed and rewritten entirely in your browser, so the photo never leaves your device. And editing EXIF does not re-compress the image, because EXIF lives in a header block, not the pixel data, so changing a tag does not touch picture quality. (More on where that block physically sits in where is EXIF data stored.)

Format limits, honestly: the editor works best on JPEG, where the EXIF block is well-standardized and easy to rewrite in the browser. HEIC (the iPhone default) stores the same tags inside a different container that browser tools round-trip poorly; convert to JPEG first with our HEIC to JPG tool, then edit. PNG stores metadata in its own chunk format that browser canvas APIs do not write reliably, so for PNG a desktop tool like ExifTool is the better choice. To confirm what a photo currently holds, drop it into our EXIF Viewer.

Which fields people edit most

You can edit almost any tag, but a handful account for nearly every real edit:

• DateTimeOriginal is the capture date and time, the single most important tag and the one most apps sort by.
• CreateDate and ModifyDate are the file-creation and last-modified dates. When you fix a wrong clock, set all three together so they stay consistent.
• GPSLatitude and GPSLongitude hold the location. Paste in coordinates to add or correct where the photo was taken.
• Make and Model name the camera or phone.
• Artist and Copyright carry your name and copyright string.

That is the short list. For the full dictionary of every EXIF field, what it means, and how it is encoded, see the EXIF tag reference. No need to repeat all of it here.

Editing the EXIF date is not the only way to date a photo

Three different things get confused, so it is worth separating them:

• Editing the EXIF date changes the hidden DateTimeOriginal tag. It is invisible in the image and only shows up in a metadata viewer or when an app sorts by it.
• Drawing a visible timestamp burns the date into the pixels themselves, in the corner of the photo, where anyone can read it without a tool. That is a separate job; use our Add Timestamp to Photo tool. A visible stamp and an EXIF date are independent, and they can even disagree.
• The file system date is the created or modified date your operating system shows in Finder or File Explorer. It is a property of the file on disk, not part of the photo, and it changes whenever the file is copied or moved. Editing EXIF does not change it, and changing it does not change EXIF.

If you want the photo's date to survive copying, sharing, and re-importing, EXIF DateTimeOriginal is the field that matters.

A note on responsible use

Editing the metadata on your own photos is completely normal. Fixing a wrong clock, adding your copyright, back-filling a location you remember, these are routine housekeeping.

What does not work is editing EXIF to misrepresent when or where a photo was taken. EXIF edits are detectable. Forensic analysts do not trust any single tag at face value; they look at consistency across the whole file (does the GPS time zone match the clock, does the camera Model match the maker note, does the JPEG compression match the claimed source). Our guide on how to tell if a photo has been edited walks through exactly these checks. Put simply, rewriting a date in the EXIF Editor is not a substitute for trustworthy capture-time proof. If you need a date you can stand behind later, capture it correctly at the moment you take the shot rather than patching it afterward.

FAQ

Will editing EXIF lower my photo quality? No. EXIF lives in a header block separate from the pixels, so a clean edit does not re-compress the image and changes the file size by only a few hundred bytes.

Can I change just one field and leave the rest alone? Yes. Our editor inserts your change and leaves every other tag byte-for-byte identical. Cheap tools sometimes overwrite the whole block; ours does not.

Does editing EXIF change what the photo looks like? No. EXIF is invisible metadata. To put a visible date on the image, use Add Timestamp to Photo instead.

Can I edit EXIF on an iPhone HEIC photo? Not directly in the browser. Convert it to JPEG first with our HEIC to JPG tool, then edit the JPEG.

How do I check my edit worked? Drop the downloaded file into the EXIF Viewer and confirm the field shows the new value.

Bottom line

To change a wrong capture date, fix or add GPS, set the camera Make and Model, or add copyright, drop the photo into our free EXIF Editor. It runs in your browser, nothing uploads, and only the fields you touch change. Edit your own metadata freely, but remember that EXIF edits are detectable and are not proof of when a photo was really taken.
