What is hidden data in a file?
Most files carry information you don't see on screen, often called metadata. Photos store the exact place and time they were taken and the phone that took them. Word and PDF files keep the author's name, the company, comments and sometimes text you deleted. Copied text can contain invisible characters.
Where do I start?
Drop any file into the box at the top of this page. It tells you what kind of file it is and what's inside, in plain English, and offers a clean copy. If you already know what you want to do, pick it under “What do you want to do?”.
Are my files uploaded anywhere?
No. Every check runs in your browser on your own device. Nothing you paste or drop is sent to a server or stored. Turn off your Wi-Fi and the tools still work.
What's free, and what's Pro?
Checking any file is free, with no limits and no account. Removing the hidden data from photos and text is free too. Pro removes it from Word, Excel, PowerPoint, PDF, video and audio files, and cleans whole folders at once.
Why do you keep Content Credentials when cleaning?
They are a signed record of how an image was made, including whether AI made it. Your location and camera details are yours to remove. A label that tells people an image is AI-generated isn't.
Does ChatGPT put hidden watermarks in text?
Not in a way anyone can confirm by looking at characters. Copied AI text often contains non-breaking spaces and similar leftovers, and this tool finds those. Companies that do watermark text do it in word choice, which no character cleaner can see or remove.
Which files can I check?
Any pasted text; JPEG, PNG, WebP and HEIC images; MP4 and MOV videos; and Word, Excel, PowerPoint and PDF documents. Cleaning documents, videos and audio is part of Pro.
