WEBP METADATA REMOVER

Remove metadata from a WebP image

A WebP file may look web-native and still contain EXIF camera records or an XMP packet. KillMetadata removes supported metadata chunks and rebuilds the RIFF container without re-encoding its VP8 or VP8L image payload; the VP8X feature header is updated consistently.

THE CLEANING PLAN

Remove what exposes you. Keep what makes the file work.

Every field is shown before the rewrite and classified by action and coverage.

Remove
  • Supported EXIF camera, GPS, author and date data
  • XMP descriptions and editing history
  • A legacy Exif-prefixed carrier when it can be normalized safely
  • Non-zero padding payloads handled by the format engine
Preserve
  • VP8 or VP8L encoded image data and the VP8X feature header
  • Transparency and animation chunks
  • ICC color profiles
  • Minimal supported orientation data when present
Outside this guarantee
  • Unknown RIFF chunks reported as a coverage gap
  • Visible information in pixels
  • Steganography
  • HEIC or AVIF files renamed .webp
  • Descriptive labels inside preserved ICC profiles, reported as partial

WHY THE ENGINE MATTERS

WebP is a RIFF container

The scanner validates every bounded RIFF chunk and identifies the real WebP signature. Supported EXIF and XMP chunks are removed or minimized while image, alpha, animation and ICC chunks are copied.

The verifier parses the rebuilt RIFF structure again. Unknown carriers and orientation-bearing XMP that cannot be separated safely must not silently become a verified-clean result.

BEFORE YOU SHARE

A four-step privacy check.

Metadata cleaning is one part of a safe sharing workflow.

  1. 01Confirm WebP detection
  2. 02Review the EXIF/XMP carrier and any readable preview
  3. 03Create the cleaned WebP
  4. 04Open the image or animation and check verification

QUESTIONS, ANSWERED

Know the boundary before you clean.

No vague “100% clean” claim.

Are my files uploaded?

No. The cleaner runs in your browser, has no upload endpoint, and only enables the file picker after its processor assets are available locally.

Is the original file changed?

No. KillMetadata reads the original and creates a separately named cleaned copy. It never overwrites the source file.

Can WebP contain EXIF?

Yes. WebP can contain EXIF and XMP chunks alongside image, animation and color data.

Will animated WebP still animate?

Supported animation and frame chunks are preserved; the compressed frames are not re-encoded.
