Remove metadata from podcast and video thumbnails
Every episode or video you publish needs a thumbnail — the cover art that shows up in a podcast app or next to a video link. It's easy to forget that a thumbnail is just a regular image file (usually JPEG or PNG), and like any photo, it can carry hidden metadata that has nothing to do with the artwork itself.
How metadata ends up in a thumbnail
Thumbnails rarely start as a clean export. They pass through a chain of tools before they're uploaded, and each one can leave something behind:
- A photo used as a base — if you built the thumbnail from a photo (a headshot, a product shot, a frame grabbed from the video), that photo's original EXIF and GPS data can survive inside the layered file and the final export.
- Design software — editing tools often stamp XMP fields with the software name, version, and sometimes your account or workspace identity.
- AI-generated art — if the thumbnail (or part of it) came from an AI image generator, it may carry Content Credentials (C2PA) metadata noting how it was made.
- Screenshots used as source material — a frame grabbed from screen-recording software can bring along that app's own metadata too.
Why it matters for creators
A thumbnail is one of the most widely distributed files a creator publishes — it gets pulled by platforms, link previews, podcast directories, and search results, often far more than any single episode page. If the source photo had GPS data from your studio or home office, or the design file reveals which freelancer or agency built it before you were ready to say, that's now attached to the most-viewed image tied to your show.
None of this is visible when you look at the thumbnail. It only shows up when something reads the file's metadata fields directly.
What scrub covers here
To be clear about the boundary: scrub cleans the thumbnail image itself, not the audio or video file it represents. A podcast MP3 or a video container (MP4, MOV) has its own metadata, and scrub doesn't scan or clean those today. But the thumbnail — the JPEG or PNG you upload as cover art — is exactly the kind of file scrub is built for.
Run it through scrub before you upload:
- Drop the thumbnail inIt's read locally — nothing is uploaded anywhere to check it.
- See what's insideEXIF, GPS, XMP, and any Content Credentials get listed plainly.
- Click CleanYou get a losslessly cleaned copy, same image quality, metadata gone. Your original is untouched.
The short version
Your thumbnail is just an image file, and image files carry metadata — even when the content is cover art, not a personal photo. Clean it the same way you'd clean any photo before it goes public. Audio and video files themselves aren't covered yet, so say so plainly if anyone asks. Get scrub free and check your next thumbnail before you hit upload.
