  • Equal-luminance colors can collapse into nearly identical shades of gray.
  • The operation affects the full image and does not preserve selected accent colors.
  • WebP browser export is intended for still images; animated WebP input is processed as a single frame.

Common questions

Grayscale WebP FAQ

Does Convert WebP to Grayscale upload my image?

No. Decoding, canvas processing, previewing, and export happen in the current browser session.

Does the downloaded file replace the original?

No. The tool creates a separate download; the source file on your device is not modified.

Will metadata remain in the result?

Canvas export normally omits camera EXIF and most ancillary metadata. Keep the original if those records matter.
