Know before you start

Important limitations

  • Enlargement cannot recover fine detail that is absent from the source.
  • Disabling the aspect-ratio lock can distort people and objects.
  • JPG output is flattened and re-encoded, so repeated saves can introduce additional compression artifacts.

Common questions

Resize JPG FAQ

Does Resize 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.
