Frequently asked questions
Will image dimensions change?
No. Exports have the same pixel width and height as the original.
Are my images uploaded?
No. Decoding, compression, and ZIP creation all happen in your browser.
Will EXIF metadata be preserved?
The export re-encodes each image. Full EXIF, GPS, HDR, and original color profiles are not guaranteed to be preserved.
