Image formats
JPEG and JPG files are common camera and phone exports. Fenwick DataClean removes common EXIF, XMP, Photoshop metadata, and comment segments. PNG and APNG files can contain text chunks, timestamps, EXIF, and private chunks. WebP and GIF files can include XMP, comments, and other metadata blocks depending on how the file was created.
Video formats
MP4, MOV, and M4V files are common outputs from phones, cameras, and editing apps. These containers can carry metadata atoms and text payloads that identify creation tools, timing, authorship, or export context. Fenwick DataClean focuses on removing recognizable metadata while preserving playable structure.
Unsupported or unusual files
Some files use proprietary structures, damaged containers, encryption, or metadata that must be handled by specialized offline tools. When a file cannot be safely cleaned in the browser, Fenwick DataClean gives a status note instead of pretending every format can be treated the same way.
Best everyday use
Use the cleaner for everyday public sharing: photos, screenshots, social assets, marketplace images, client media, product demos, short clips, and files that need a cleaner public copy. Keep originals in a private archive when you need untouched metadata for records.
How to choose the right workflow
For photos and screenshots, clean the file, open it, and check visible details before upload. For videos, clean a copy and play the output before publishing. For files connected to records, ownership, contracts, investigations, or regulated work, preserve the original and share only the cleaned copy when sharing is appropriate.
Why unsupported files are handled carefully
A tool that claims to clean every file perfectly can create a false sense of safety. Some metadata is deeply embedded, proprietary, encrypted, or tied to playback. Fenwick DataClean is designed to be honest about common formats and cautious when a file cannot be safely changed in a browser.
Current focus
The current product focus is everyday privacy for widely shared images and videos. That includes JPEG, PNG, APNG, WebP, GIF, MP4, MOV, and M4V files. Future support can expand when a format can be cleaned without compromising speed, clarity, or file integrity.
What to do with other formats
If you need to clean a PDF, office document, RAW photo, professional archive, or unusual video container, use a workflow designed for that format. Different file families store metadata differently, and some require tools that can inspect embedded fonts, layers, revision history, thumbnails, annotations, or complex container structures.
How output status should be read
A cleaned status means the tool completed its supported cleaning process for that file type. A status note that says no common metadata was found does not prove the file has no possible metadata anywhere; it means the common targets for that supported format were not detected. For sensitive work, verify with a second trusted tool before publishing.
Choosing the right file before upload
Start with the final file you actually plan to share. If you clean an early draft and then export a new version from another app, the new export may add metadata again. Clean the final public copy after the last edit, compression, or conversion step.
Format limits protect file integrity
Conservative support is a feature, not a weakness. A metadata cleaner should avoid damaging files just to claim broader compatibility. If Fenwick DataClean cannot safely handle a structure in the browser, the better outcome is a clear note and an unchanged original rather than a corrupted download.
Why the list is updated carefully
Adding a format means understanding how that format stores hidden information and how to rewrite it without breaking normal use. The supported list should grow when testing shows that users can clean files, download outputs, and open them reliably across common devices and browsers.
