The short answer
Image metadata is data stored inside a file but not visible in the picture: camera and lens, exposure settings, capture date, editing software, copyright and, on most phones, the GPS coordinates of where the photo was taken. To check it, open the file in a metadata reader like the tool above. To remove it, export a new copy rather than editing the original, then verify the export before publishing.
The three metadata standards inside your images
“Metadata” is not one block of data. Most photographs carry up to three separate standards, written by different tools at different moments, and they do not carry the same risk. Knowing which is which is what lets you strip the sensitive fields without losing the useful ones.
| Standard | What it holds | Privacy risk |
|---|---|---|
| EXIFExchangeable Image File Format | Camera make and model, lens, shutter speed, aperture, ISO, orientation, capture date and time, and GPS coordinates on most phones. | Highest. This is where location data lives. |
| IPTCInternational Press Telecommunications Council | Creator, credit line, copyright notice, caption, keywords and licensing details. Added by photographers and picture desks rather than by the camera. | Low. Usually the metadata you want to keep. |
| XMPExtensible Metadata Platform | An XML container Adobe tools use for edit history, ratings, labels and copyright, often duplicating IPTC fields. | Low to medium. Can reveal software and editing history. |
Which formats actually store metadata
The format decides what can be stored, and therefore what you need to check. If you only remember one row from this table, make it the first: JPEG from a phone camera is the file most likely to be carrying the coordinates of your home.
| Format | Metadata support | GPS likely? | What to watch for |
|---|---|---|---|
| JPEG / JPG | EXIF, IPTC, XMP | Yes, on most phones | The default camera format and the most common source of leaked GPS data. |
| HEIC / HEIF | EXIF, XMP | Yes, on most phones | The modern iPhone default. Carries the same location fields as JPEG. |
| TIFF | EXIF, IPTC, XMP | Yes | Common in archives and print workflows, where metadata is deliberately rich. |
| PNG | EXIF and XMP in optional chunks | Possible but uncommon | Screenshots and exports rarely carry GPS, but editors can write chunks. |
| WebP | EXIF and XMP in optional chunks | Possible but uncommon | Whether data survives depends on the tool that produced the file. |
| GIF | No EXIF block; comment extensions only | No | Little metadata risk, but comments can still carry text. |
| SVG | Arbitrary XML metadata elements | No | Plain text: editor names, layer names and comments are directly readable. |
How to remove image metadata
There is one principle behind every method below: export a new file instead of editing the original. Writing a fresh file from the decoded pixels leaves the metadata behind by default, while editing in place relies on the tool finding and clearing every block. Keep the original as your archive and publish the export.
| Platform | Steps | Worth knowing |
|---|---|---|
| Windows 10 and 11 | Right-click the file, choose Properties, open the Details tab and select Remove Properties and Personal Information. Choose to create a copy so the original keeps its data. | Clears the fields Explorer knows about. Some maker-specific blocks can survive, so verify sensitive files. |
| macOS | In Photos, use File then Export and untick Location Information. Preview shows metadata under Tools then Show Inspector but does not reliably strip every field. | Exporting is more dependable than editing in place. |
| iOS and iPadOS | In Photos, tap Share, tap Options at the top of the sheet and turn Location off before sending or saving. | The setting applies to that share action only, not permanently. |
| Android | Open the photo details in Google Photos or your gallery app and remove the location where the option is offered. | Availability varies by manufacturer and app version. Check the result rather than assuming. |
| Any browser | Re-export the image through a browser-based tool. Writing a new file from the decoded pixels normally leaves the metadata behind. | Depends on browser and output format. Not a guarantee for sensitive files. |
| ExifTool (command line) | The reference tool for reading and writing metadata across formats, and the one to reach for when you need certainty. | Requires installation and a terminal, but it is the most thorough option. |
Whichever route you take, check the result. Re-open the exported file in a metadata reader and confirm the fields you wanted gone are actually gone. That verification step takes seconds and is the difference between assuming a file is clean and knowing it. The full guide to removing image metadata walks through the process file type by file type.
Does metadata matter for image SEO?
Less than most checklists suggest. Google has been explicit that it does not use most EXIF fields as ranking signals, so writing keywords into the camera comment field is wasted effort. The one metadata standard with a documented search benefit is IPTC photo metadata for licensing: Google Images can read the licensor and rights fields and show licence information alongside an image, which matters if you sell or license photography.
What does move the needle for images is more mundane: a descriptive filename, alt text that describes the picture rather than repeating a keyword, dimensions that match the layout, and a file weight that does not slow the page down. If you came here looking for an SEO win, those four are where it is. The image SEO checker tests all four in one pass, and the image SEO checklist covers the full pre-publish routine.
Metadata and visible privacy risks are different
Removing metadata is only one part of safe publishing. A photo can have no readable EXIF data and still reveal private information through visible details such as addresses, documents, screens, badges, reflections or location clues in the background.
| Risk type | Example | Action before publishing |
|---|---|---|
| Embedded metadata | Camera data, timestamps, GPS-related fields | Export a clean copy and verify with a dedicated tool. |
| Visible personal details | Names, documents, screens, IDs or addresses | Crop, blur or choose a safer image. |
| Location clues | Street signs, reflections, landmarks or house numbers | Review the full image, including background details. |

Common mistakes
Assuming the upload will clean the file
Platform stripping is a side effect of re-encoding, not a privacy feature. It varies between services and changes without notice. If the data must not leave your device, remove it first.
Editing the original instead of exporting a copy
Stripping metadata from your only copy destroys information you may want later: capture dates, camera settings and your own copyright line. Keep the original and publish an export.
Removing the copyright along with everything else
A blanket strip also deletes the IPTC creator and rights fields. If you want attribution or licence details to travel with the image, remove the EXIF location and keep IPTC.
Checking metadata but not the picture
The most common real-world leak is visible, not embedded: a delivery label, a school uniform, a screen full of email, a street sign behind the subject.
Trusting one tool for a sensitive file
Different tools read and write different blocks. When the stakes are real, check the output with a second tool before publishing.
Pre-publish metadata checklist
- Read the file’s metadata before you touch anything, so you know what is there.
- Check specifically for GPS coordinates if the photo came from a phone.
- Decide what should stay: copyright and credit are usually worth keeping.
- Export a copy rather than stripping the original.
- Re-check the export and confirm the sensitive fields are gone.
- Scan the visible picture for addresses, documents, screens and reflections.
- Be extra careful with photos of documents, homes, workplaces or children.
- For anything genuinely sensitive, verify with a second, dedicated tool.
Frequently asked questions
What is image metadata?
Image metadata is information stored inside the image file that is not part of the picture itself. It can describe the camera and lens, exposure settings, the date and time the shot was taken, the software used to edit it, copyright details and, on many phones, the GPS coordinates of where the photo was taken.
How do I check the metadata of an image?
Upload the image to the checker above and it will read the metadata your browser can access, along with dimensions, format and file size. Nothing is uploaded to a server. On Windows you can also right-click the file, open Properties and look at the Details tab; on macOS, open the image in Preview and choose Tools then Show Inspector.
How do I remove metadata from an image?
The quickest reliable method is to re-export the image rather than edit the original. On Windows, right-click the file, open Properties, go to Details and choose Remove Properties and Personal Information. On macOS, export from Photos with Location Information unchecked. On iOS, use the share sheet, tap Options and turn off Location. For anything sensitive, verify the result with a dedicated metadata tool such as ExifTool.
Does removing metadata change how the image looks?
Removing metadata does not change the pixels, so the picture looks identical. It only strips the descriptive fields stored alongside the image. Re-encoding the file during export can affect quality, which is a separate issue: export at a high quality setting if you want the visual result to stay the same.
Do social platforms remove metadata when I upload?
Most large platforms strip most metadata when they re-encode uploads, but behaviour differs between platforms and changes over time, and some services keep more than others. Treat platform stripping as a side effect you cannot rely on, not as a privacy step. If the data must not leave your device, remove it before uploading.
Does a screenshot contain metadata?
A screenshot has no camera or GPS data because no camera was involved, but it can still record the device, the operating system and the moment it was captured. The bigger risk with screenshots is visible content: notifications, file paths, account names, email addresses and open tabs are all readable in the picture itself.
Which image formats store metadata?
JPEG, TIFF and HEIC carry EXIF natively and are the formats most likely to hold GPS data. PNG and WebP can carry EXIF and XMP in optional chunks. GIF has no EXIF block but supports comment extensions, and SVG is XML, so it can contain metadata elements and even editor history as plain text.
Does image metadata affect SEO?
Not in the way filenames and alt text do. Google has said it does not use most EXIF fields for ranking, so stuffing keywords into metadata does not help. The exception worth using is IPTC photo metadata for licensing, which Google Images can surface as licence details next to an image. What genuinely affects image SEO is the filename, the alt text, the dimensions and the file weight.
Can a browser check every metadata field?
No. A browser reads what the image decoding APIs expose, which covers the common fields but not every proprietary or maker-specific block. For privacy-sensitive files, treat the browser check as a first pass and confirm with a dedicated metadata tool before publishing.
Does exporting through Canvas remove metadata?
Re-encoding an image through the browser Canvas API normally drops EXIF metadata, because the export writes a new file from the decoded pixels. It should not be treated as a guarantee: behaviour varies by browser and output format, so verify the result if the file is sensitive.
Should I publish the original photo or a copy?
Publish an exported copy and keep the original private. The original is your archive: it holds the full quality and the full metadata. An export lets you control the dimensions, the file weight and which fields travel with the image.
Is removing metadata enough to make a photo safe to publish?
No, and this is the mistake worth avoiding. A file with no readable EXIF can still expose a home address on an envelope, a name badge, a screen, a reflection or a recognisable street corner in the background. Check the visible content of the image as carefully as you check its metadata.
