Support notes live here so the tool page can stay focused.

This page keeps the product boundaries clear: what formats are best for reading, where editing is supported, and how privacy-sensitive tags are handled.

Local by default

Metadata reading happens in the browser. JPEG edits and cleanup actions export a new file instead of touching the original photo.

Best formats: JPEG gives the fullest experience because it supports reading, editing, GPS removal, and removing the EXIF APP1 segment.
Viewer fallback: If an image has no embedded EXIF, the tool still falls back to format and dimensions when possible, including HEIC files that need local decoding first.
Reading support: The current metadata pipeline is optimized for in-browser viewing across JPEG, TIFF, PNG, WebP, HEIC, HEIF, AVIF, and GIF. Tag coverage still depends on what each file actually contains.
Writing support: EXIF editing, GPS removal, and EXIF segment removal are intentionally limited to JPEG. Removing EXIF deletes the EXIF APP1 segment only, not XMP, IPTC, or other metadata groups.

Read faster

The tool starts from a compact overview, then the full tag table on the same page.

Browser-side reading supports JPEG, TIFF, PNG, WebP, HEIC, HEIF, AVIF, and GIF. HEIC previews can still fall back to a local conversion path.

Edit carefully

Writing and cleanup stay limited to JPEG so the behavior remains predictable and downloads always preserve the original image.

What a photo knows about itself.: What a camera and an editor write into a photo file, which standards they use, and why the same fact can appear three times with three different values.
Reading a photo on the device that took it.: Where iPhone and Android show a photo's camera settings, date and location, what those built-in panels leave out, and how to read the raw tags in a mobile browser.
What is worth taking off before you publish.: Which parts of a photo's metadata actually matter when you publish, what a cleaning tool can and cannot take off, and the order worth doing it in.

What it can do

Remove EXIF data: Drop a photo and download a copy with its embedded metadata removed. JPEG loses its EXIF segment losslessly; HEIC, PNG, WebP and the rest are re-encoded. Nothing is uploaded.
Remove GPS location: See the coordinates a photo is carrying, then download a copy without them. JPEG loses the location tags and keeps everything else. Nothing is uploaded.
Edit JPEG EXIF: Change the title, author, description, copyright, software and capture time on a JPEG, then download the edited copy. Runs locally; your original file is never modified.
XMP, IPTC and ICC viewer: Read every metadata group a file carries — EXIF, XMP, IPTC, ICC, maker notes — grouped and exportable as JSON. For asset QA, forensics and debugging a pipeline. Nothing is uploaded.
Open several photos: Open up to fifty photos, see which of them carry a location, and take the whole set out as a spreadsheet. Nothing is uploaded, and the originals are never written to.

By file format

HEIC metadata viewer: Open a HEIC or HEIF and read its EXIF, GPS and Apple maker notes in the browser, even where the browser cannot display the image. Nothing is uploaded.
PNG metadata viewer: PNG has no EXIF segment. See the tEXt, iTXt and eXIf chunks a PNG is actually carrying, read locally in your browser. Nothing is uploaded.
WebP metadata viewer: WebP stores metadata in RIFF chunks, and only in its extended form. See what a WebP is carrying, read locally in your browser. Nothing is uploaded.
TIFF metadata viewer: TIFF is where EXIF came from. Read a TIFF's image file directories, tags and byte order in the browser, even though no browser can display one. Nothing is uploaded.
AVIF metadata viewer: AVIF uses the same container as HEIC and the opposite licensing, which is why your browser can display one. Read its metadata locally. Nothing is uploaded.
GIF metadata viewer: A GIF has no EXIF and no colour profile. See the comment and application extension blocks it does carry, read locally in your browser. Nothing is uploaded.
RAW metadata viewer: Most raw files are TIFF underneath, which is why their EXIF, GPS and maker notes can be read in a browser that cannot display one. Nothing is uploaded.

Keep the boundaries explicit.

The tool is easier to trust when reading, editing, and cleanup limits are stated clearly in one place.

Does this upload my photos to a server?

No. The analyzer reads image metadata directly in your browser. Files stay on the device unless you choose to share them elsewhere.

Which image formats work best?

JPEG gives the fullest experience because it supports reading, editing, GPS removal, and EXIF segment removal. TIFF, PNG, WebP, HEIC, HEIF, AVIF, and GIF can be inspected too. Writing remains JPEG-only.

Can the tool detect GPS coordinates?

Yes. When a photo includes location metadata, the overview shows a GPS banner. For JPEG files you can download a new copy without those tags.

Can I edit or delete metadata here?

Yes, for JPEG files. You can remove GPS tags from the overview. The edit view can change common fields and remove the EXIF APP1 segment — not XMP, IPTC, or other groups. Downloads are always a new copy.

Can I export the raw metadata?

Yes. After a file is parsed you can copy the normalized JSON output for debugging, QA workflows, or support notes.
