## A Local Guide to Cleaning PDF, Image, and Video Metadata   AI Metadata Cleaner is a free in-browser metadata and AI provenance cleaner for images, video, PDF, and RAW files. It inspects and strips EXIF, GPS, XMP, IPTC, C2PA Content Credentials, and AI generator tags from Stable Diffusion, Midjourney, GPT-Image-2, and Veo 3. The work runs locally in your browser via WebAssembly, with zero file uploads. It is 100% free and no signup is required.   People usually meet this problem in a PDF. A document exported from a desktop app can still list an author, a producer tool, timestamps, and an XMP packet. That is separate from the words on the page, and it travels with the file when you email it or drop it in a shared folder. The same habit shows up in photos and video: a JPEG keeps EXIF and GPS, a PNG from a generator keeps prompt metadata, and an MP4 keeps container tags. One local tool can inspect all of those cases.   ### Why a browser tool is enough   There is no account to create and no server copy of the file. You open the website, the WebAssembly modules run in the tab, and you download the cleaned result. That design matters for client drafts, unreleased creative work, and any file you would rather not upload just to remove a hidden field.   ### What it can strip   EXIF camera and capture data, including GPS coordinates on photos. XMP and IPTC blocks. C2PA Content Credentials stored as container metadata. AI generator tags associated with Stable Diffusion, Midjourney, GPT-Image-2, and Veo 3.   Supported file formats are JPEG, PNG, WebP, AVIF, HEIC, MP4, MOV, WebM, PDF, and RAW. Images, video, documents, and camera RAW files therefore share one workflow instead of four unrelated utilities.   ### PDF author, XMP, and the rest of the container   For documents, start with the [Browser-Based PDF Document Metadata, Author & XMP Sanitizer](https://aimetadatacleaner.pro/clean-pdf-metadata). That page is the PDF-focused entry to the same free cleaner. Use it when a proposal, a portfolio, or a white paper should not advertise the author name or the XMP packet that the editor wrote into the file. After the PDF looks right, the same site can clean a cover image or a demo video so the package you send is consistent.   ### Step by step   Open AI Metadata Cleaner in the browser. Skip any thought of signing up; none is required. Select a PDF, or switch to an image, video, or RAW file if that is the asset you need to publish. Inspect the report. Confirm whether EXIF, GPS, XMP, IPTC, C2PA Content Credentials, or AI generator tags are present. Strip the container metadata locally. WebAssembly does this in the tab, and you download the result. The original is not uploaded. If the file is a PDF, re-check author and XMP fields. If it is media, re-check GPS and generator tags before you send it.   ### Honest boundary   Pixel-domain SynthID watermarks are detected and explained. They live in the image itself, not in the metadata container. AI Metadata Cleaner strips container metadata and does not claim to erase those pixel watermarks. A platform can also add its own label later; this tool only changes the file you download.   ### FAQ   Is the PDF path a separate paid product? No. PDF cleaning is part of AI Metadata Cleaner, which is free, with no signup, and it runs locally. Which formats are supported? JPEG, PNG, WebP, AVIF, HEIC, MP4, MOV, WebM, PDF, and RAW. Will GPS be removed from a photo? Yes. GPS is among the EXIF location fields the cleaner strips, together with XMP, IPTC, and C2PA container markers when they are present. Does it upload the document? No. There are zero file uploads. Processing stays in the browser via WebAssembly. Can it remove SynthID? It can detect and explain pixel-domain SynthID watermarks. Removing them is outside the tool. Container metadata is what gets stripped.   Use AI Metadata Cleaner when a file should leave your computer without an author line, a GPS point, or an AI provenance tag riding along in the container. Open it, inspect, strip, and download.
