Important limitations

  • Upscaling creates interpolated pixels and does not restore source detail.
  • Unlinked width and height values can distort the original geometry.
  • WebP browser export is intended for still images; animated WebP input is processed as a single frame.

Common questions

Resize WebP FAQ

Does Resize WebP 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.
