About SynthOff
Most image tools ask you to upload your files. SynthOff never does.
What SynthOff is
SynthOff is a free toolkit for the hidden side of images: the metadata, labels and credentials that travel inside a file. It has four tools.
Why it exists
A photo can carry your GPS location, your name and your camera's serial number. An AI image can carry labels that platforms read and act on. Most people never see any of it.
SynthOff shows you what is inside a file, lets you remove what you don't want to share, and converts files without sending them anywhere.
How it stays private
Every tool runs inside your browser tab. The heavy work uses WebAssembly builds of proven libraries, served from this website. There is no upload endpoint, no account and no database, and the site blocks connections to any other server. Read the privacy policy for the details.
What it doesn't do
SynthOff doesn't detect AI from pixels. It reads what a file declares. It can't confirm whether an invisible watermark such as SynthID is still present after cleaning. And removing metadata doesn't change platform rules: if an image uses AI, you may still need to disclose it.
Who makes it
SynthOff is developed by Amirul Sizan, a digital media entrepreneur based in Bangladesh. It is powered by Bongo Wiki, a youth-focused digital news and storytelling platform.
