What a photo still carries after you hit export

After I export a photo, can it still carry GPS, camera EXIF, and C2PA?

A photo can still carry GPS, camera EXIF, XMP, and a C2PA credential after you export it. Those live in different parts of the file, and a social app may recompress the upload into a new file. Check the file you are about to post. Cleaning in this browser writes a new file and leaves the original alone.

Creators usually mean three different jobs when they say “remove metadata from a photo”: strip GPS, strip camera EXIF, or strip provenance credentials. They live in different places, and social apps do not treat them the same.

The layers

EXIF is the camera envelope: make, model, lens, timestamp, sometimes a serial, and — on phones — GPS. It sits in JPEG APP1, PNG eXIf, WebP EXIF, or QuickTime udta.

GPS / location is usually an EXIF GPS IFD (decimal degrees) and sometimes duplicated in XMP. Removing “location” without touching other EXIF is a different product promise than a full strip; this kit’s sharing copy re-encodes the image through Canvas, which drops the supported EXIF block.

XMP is the sidecar-in-the-file: Lightroom history, contact fields, rights strings, nested provenance pointers.

IPTC caption, keywords and contact records often travel as IPTC-IIM and/or XMP. A Canvas re-encode drops them with the rest of the header metadata on JPG/PNG/WEBP.

C2PA / Content Credentials are signed provenance claims (JUMBF in JPEG, caBX in PNG, UUID boxes in MP4). They are not “EXIF with a new name”. A platform may display a label from C2PA, from its own classifier, or from something you cannot see in the file.

Format differences

JPEG — richest EXIF/XMP/C2PA surface. Re-encoding at high JPEG quality drops headers; it is not a bit-identical pixel copy.
PNG — text chunks, eXIf, caBX. A re-export can keep the RGB grid while changing container, alpha channel, and byte size.
WEBP — EXIF/XMP chunks exist; Canvas re-encode drops them.
HEIC/HEIF — common iPhone original. This cleaner does not decode or strip HEIC today. Export JPEG/PNG/WEBP from Photos first. Do not assume a browser thumbnail is a cleaned master.
MP4/MOV — metadata lives in boxes (udta, meta, C2PA UUID). Samples in mdat are copied, not transcoded.

What platforms often rewrite

Messaging apps and social uploads frequently recompress, strip, or replace headers. That can look like “the platform removed GPS” when it actually made a new file. It can also keep a credential you thought was gone, or add an AI label from a signal that is not in EXIF.

Inspect the file you still have, then decide. A header does not tell you how a platform ranks the post.

A practical workflow

Inspect the original with Metadata Cleaner (or the locale homepage). Look at GPS, EXIF, XMP and any C2PA packet before you delete anything.
Export a sharing copy. Keep the original elsewhere.
Inspect the downloaded copy, not the file you still have open. If a product re-scan is incomplete or still reading the original, treat the job as incomplete.
If the question is “was this made by ChatGPT / does it still carry Content Credentials?”, use AI Image Origin Detector — inspection is local; official OpenAI C2PA/SynthID is optional and uploads.
Screenshots are a different object. They usually destroy C2PA. They can still show faces, addresses, and OCR-readable UI. See the screenshot notes linked below.

Limits

The homepage cleaner strips supported container metadata on JPEG, PNG, and WebP: EXIF, GPS IFD, XMP, IPTC, and C2PA packets it can see. It does not remove visible scene content or pixel-domain watermarks such as SynthID. Stored pixels, orientation, dimensions, and ICC can still change with the format and the export path.

An ICC colour profile can remain after GPS and EXIF are gone. Orientation and pixel dimensions can also change with the export path. One JPEG is not a result for every image, and a missing GPS block is not a promise that every file is clear.

This does not guarantee a platform will drop an “AI info” label. It does not process HEIC originals.

PNG can carry a provenance container

The homepage cleaner strips supported EXIF, GPS, and C2PA containers from JPEG, PNG, and WebP in this browser. Files stay on the device; nothing is uploaded.

This step clears file-header containers; it does not touch picture watermarks or verify signatures.
