Pick a .zip file. It gets compressed and packed into a downloadable image - no URL length limit involved. Share the image as a downloaded file or attachment, never pasted inline into chat apps or social media (they recompress images, which would corrupt the data). Anyone can drop that image into the box below on this same page to get file.zip back. Nothing is uploaded or stored anywhere.
Have an exported image? Upload it here to decode it back to file.zip:
