原文外掛簡介
Every image you upload carries data you can’t see. A phone photo can include the exact GPS spot where it was taken. Editing apps add their own notes. AI image tools add records that say which tool made the file and when, and some save the full prompt and workflow inside the PNG.
Your visitors don’t need any of it to see the image. It makes files bigger, and some of it is personal information you probably never meant to publish.
This plugin takes it out. It removes:
C2PA Content Credentials and JUMBF data (JPEG APP11, PNG caBX, WebP C2PA)
XMP, including the IPTC “trainedAlgorithmicMedia” tag that marks an image as AI-generated
EXIF data, such as camera model, software and GPS location
IPTC and Photoshop blocks
PNG text chunks, such as Stable Diffusion prompts, ComfyUI workflows and Adobe XMP
JPEG comments
JPEG, PNG, WebP and AVIF files are edited directly, byte by byte. The pixels are never decoded and saved again, so there is no quality loss at all. Other formats are handled through Imagick when your server has it.
Want to check a single photo without installing anything? Try the free online version, the Image Metadata Remover. It runs in your browser, so your images never leave your computer.
How it works
Once it’s active, every new upload is cleaned automatically: the original, the scaled version and every thumbnail size.
For images already in your Media Library, go to Media > WDF AI Metadata Remover. Run a scan first. It doesn’t change anything, it just shows you which images carry which kind of metadata. Then clean them one at a time, or clean everything the scan flagged in one click.
You also get:
A “Strip AI metadata” link on each image in the Media Library list
A column showing whether each image is Flagged, Clean or Cleaned
WP-CLI commands for large libraries
What stays the same
The pixels. Nothing is re-encoded.
The ICC color profile, so colors look right. You can turn this off in the settings.
The orientation tag on JPEGs, so phone photos still display the right way up.
Your titles, captions and alt text. WordPress stores those in the database, not inside the image file.
What it doesn’t do
Some AI providers hide an invisible watermark in the pixels themselves, such as Google’s SynthID. This plugin works on metadata only, so it leaves those alone.
Please only use it on images you own or have permission to change. It isn’t meant for stripping copyright information from other people’s work.
Who made it
WDF AI Metadata Remover is built and maintained by Web Designer Factory, a web design and development agency in Dallas, Texas. It’s free. There is no paid version and nothing to upgrade to. If it saves you time, you can switch on a small credit link in your site footer from the settings page. It’s off unless you turn it on.
