Metadata Remover: What It Actually Strips

A metadata remover deletes the hidden fields a file carries alongside its visible content: camera model and settings, GPS coordinates, author and copyright names, software versions, edit history, document titles, and in many photos a small embedded copy of the image itself. What it removes depends heavily on the file type, and what it misses depends heavily on the tool.

This is the buyer’s version of the question. If you already know you only want GPS off a photo, the step by step for that is here. What follows is the wider picture: the categories of metadata, what no remover can do for you, and the two or three things worth checking before you trust one.

The short answer

Most metadata removers handle EXIF on JPEGs well and everything else unevenly. A good one will:

• Strip EXIF, IPTC and XMP from images, including the embedded thumbnail
• Rewrite PDF document properties instead of blanking the visible ones
• Let you keep orientation so photos don’t come out sideways
• Process the file on your machine, not on a server

A weak one strips the obvious camera fields, leaves the thumbnail and the XMP block intact, and uploads your file to do it.

The categories of metadata

Camera data (EXIF)

The block most people mean when they say metadata. Make, model, lens, ISO, aperture, shutter speed, exposure compensation, flash state, capture date and time, and GPS latitude, longitude and altitude if location services were on. It also holds orientation, which matters more than it sounds. You can look at all of it in the EXIF viewer before you decide what to delete.

Authorship and rights (IPTC and XMP)

A separate set of fields, often written by Lightroom, Photoshop, a photo agency, or a phone’s editing app. Creator, credit line, copyright notice, headline, caption, keywords, location names typed by hand rather than recorded by GPS. IPTC and XMP survive plenty of “EXIF removers” untouched, because those tools only clear the EXIF block. A photo can have its GPS gone and still say who shot it and for whom.

Document properties (PDF and Office)

PDFs carry Title, Author, Subject, Keywords, Creator (the app that made the content) and Producer (the app that wrote the file), plus creation and modification timestamps and an XMP packet that often duplicates all of it. Word, Excel and PowerPoint files add last-saved-by, total editing time, company name, revision number, and sometimes a list of previous authors. Exporting a Word file to PDF usually carries the author name straight across.

Embedded thumbnails and previews

This one catches people out. A JPEG can contain a small JPEG of itself inside its EXIF block, typically 160x120. It was generated when the shutter fired. If you crop a face or a licence plate out of a photo and your editor updates the pixels but not the thumbnail, the thumbnail still shows the uncropped original. It has happened in real cases. A metadata remover that skips the thumbnail leaves a viewable copy of the pre-edit image inside the “clean” file.

Edit history and software traces

XMP history entries listing each save, software names and versions, and in some formats a document ID that stays constant across derivative files. Useful for tracing two files back to one source.

What typically hides in each file type

File type	Commonly present	Watch for
JPG	EXIF, IPTC, XMP, embedded thumbnail	Thumbnail surviving a crop; XMP left behind
PNG	Text chunks, software name, timestamps	Some tools ignore tEXt/iTXt chunks entirely
WebP	EXIF and XMP chunks	Converters often copy them across silently
TIFF	Full EXIF plus layers of maker notes	Very large private maker note blocks
HEIC	EXIF and GPS, same as JPEG	Cannot be rewritten without re-encoding
PDF	Info dictionary, XMP, timestamps, producer app	Old values kept in earlier revisions of the file
DOCX / XLSX	Author, last saved by, editing time, company	Carries into exported PDFs

What a metadata remover cannot do

It cannot anonymise the picture. Removing coordinates does not remove the street sign, the house number, the view from the window, or the face in the frame. Pixels are their own channel. If someone could identify the place by looking at it, an empty EXIF block changes nothing.

It cannot undo what has already been shared. Instagram, Facebook, WhatsApp and Discord strip EXIF GPS on upload, but a file you emailed last week is still out there with everything in it.

And for PDFs, hiding fields in a viewer is not the same as deleting them: a proper remover rewrites the file so the values are gone from the bytes, which is what our PDF metadata tool does.

Local or uploaded: the difference that matters

If you are removing metadata for privacy reasons, sending the file to a server first is self-defeating. You have handed over the exact data you wanted deleted, plus your IP address and a timestamp, and you are trusting a retention policy you cannot inspect.

Two ways to check any tool, including ours:

1. Open DevTools with F12, go to the Network tab, clear it, then drop a file in. If the file bytes get POSTed anywhere, the tool uploaded your file. A local tool shows no request at all.
2. Turn off your wifi and reload the page. Load the file, run the removal, download the result. If it still works offline, nothing left your machine.

The tools on geotaggingimage.com run in the browser using WASM ExifTool for images and pdf-lib for PDFs. No account, no watermark on the output. The free tier has a daily operation cap and a limit of 5 files per batch; Pro raises the batch to 50 and drops the daily cap.

Selective removal is usually the right setting

Wiping everything is blunt. Two fields are worth thinking about before you do it.

Orientation. Phones store photos in the sensor’s native orientation and add an EXIF orientation tag telling viewers to rotate. Delete that tag with a naive remover and the photo displays sideways or upside down everywhere. A decent tool keeps orientation by default or rotates the pixels to match before dropping it. If your stripped photos come out rotated, that is the cause.

Copyright and credit. Photographers usually want the opposite of a full wipe: GPS and camera serial gone, creator and copyright kept. That is a per-field choice, not an all-or-nothing switch.

The photo metadata remover handles both cases. In practice:

1. Drop the photo onto the page (JPG, PNG, WebP and TIFF are supported).
2. Check what is actually there first if you are unsure, using the viewer.
3. Choose whether to clear everything or keep orientation and rights fields.
4. Click Download and the rewritten file comes back with nothing uploaded.

The PDF equivalent lives at tools.geotaggingimage.com/pdf/metadata, which shows the existing Title, Author, Subject, Keywords, Creator and Producer values and rewrites the file without them.

HEIC is a partial exception. HEIC files can be read, but writing them back would mean re-encoding to JPEG, so we do not pretend otherwise. Convert with HEIC to JPG first if you need a clean, writable file.

One claim to ignore

Metadata advice often sits next to the idea that geotagging a photo helps your Google rankings. It does not. Google strips EXIF from Business Profile uploads, has said it is not a ranking factor, and a controlled test found no measurable effect. Geotagging is for organising, licensing and proving where a photo was taken. What geotagging is actually for covers the rest.

A checklist before you trust a metadata remover

• Run a file through it, then open the output in an EXIF viewer. Do not take the “done” message at face value.
• Check for XMP and IPTC fields specifically, not only the camera fields.
• Check the embedded thumbnail if the image was cropped.
• Watch the Network tab, or pull the plug and see if it still works.
• Confirm the photo still displays the right way up.
• Keep the original somewhere. Stripped metadata is not recoverable from the stripped copy.

If you want to know what each field means before you decide what to keep, photo metadata explained goes field by field.
