What does a free account add?
Every finished upscale saved to a library you can reopen and export from any device. Batches and Cloud HD are part of Pro.
Signing in is optional and free. With an account every finished upscale is saved to your library (newest first, reopen and export as PNG, JPEG or WebP) and you can open it from any device. The tool still takes one image at a time; batches of up to 50, Cloud HD and video are part of Pro.
Sign in with Google or an email code; there is no password to keep. The library holds up to 500 images and 5 GB on a free account.
