Important limitations

  • Pixelation covers the whole canvas rather than a selected privacy-sensitive region.
  • Pixelation should not be treated as secure redaction for confidential information.
  • JPG output is flattened and re-encoded, so repeated saves can introduce additional compression artifacts.

Common questions

Pixelate JPG FAQ

Does Pixelate JPG 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.
