No. Files remain on your device and are processed by browser APIs.

PNG export is lossless for pixels, but exact file-level lossless optimization depends on browser encoder support.

Will EXIF metadata stay?

Canvas export usually strips EXIF and GPS metadata.

Why can output be larger?

PNG or high-quality output can be larger than the source, especially after format conversion.
