A free online image metadata remover that doesn't upload anything

This is an online image metadata remover in the literal sense: it lives at a web address and there is nothing to install. It is not, however, an upload service. There is no endpoint that receives your photo. Every byte is read, parsed and rewritten by code running inside your own browser.
That distinction has practical consequences. There is no file size cap, because there is no upload to time out. There is no queue, because there is no shared server. And there is no retention policy for you to take on trust, because we never receive a file to retain. You can confirm all of this yourself: open your browser's Network tab and clean an image — you will see no requests. Install the site and switch off your network, and it still works.

What an image metadata remover actually does.

Every photo is two things at once: a picture, and a written record of the circumstances in which it was made. An image metadata remover deletes the second part and leaves the first alone. That record is stored in three overlapping standards — EXIF, IPTC and XMP — and between them they hold your GPS coordinates, your camera's serial number, the exact second of capture, the software you edited with, and very often your name.

None of it is visible when you look at the image. All of it travels with the file when you email it, message it, or hand it to a client.
Lossless removal, which is the part most tools get wrong

There are two ways to build a metadata remover. The easy way is to draw the image onto a canvas and export it — three lines of code, and the metadata disappears because canvas has no concept of metadata. It also decodes and re-encodes your photo, so what you get back is a re-compression of your original rather than your original with the tags removed. Do it twice and the loss compounds.

The harder way is to understand the file format. Image containers keep the compressed picture and the metadata in separate places, so if you can read the structure you can remove one without touching the other. That is what this tool does, with a dedicated parser for each format: JPEG marker segments, PNG chunks, WebP RIFF chunks, TIFF directories, and the ISO box structure behind HEIC, AVIF, MP4 and MOV.

The result is that cleaning a file costs you nothing. After every removal the finished file is parsed again from scratch to list anything remaining, and both files are decoded so every pixel can be compared against the original. When the tool reports zero pixels changed, that is a measurement taken on your machine, not a claim.
