Frequently asked questions

How is the free upscale limited?

Each Google account gets 2 free pictures, usable within 30 days of the first one. No renewal. The output is up to 8 MP (enough for 4K).

Do you keep my picture?

The original is deleted as soon as it is processed and the result after 30 minutes. We never use your pictures for training.

Do I need to install anything?

No. Sign in with Google, drop a picture and wait one to two minutes. JPG, WebP and PNG all work; your browser converts it to PNG before sending.

Are editing and downloading limited?

Editing in the browser is unlimited. Downloads are limited to 5 per account. For unlimited export, try bFlow free for 7 days.

Does the 7-day bFlow trial cost anything?

No. No card needed: sign in with this same Google account. Exports carry no watermark.

Why can I not run it right now?

The shared free runs for today or this month may be used up, or the machine is busy. You have not lost any of your own runs; try again later or try bFlow, which runs on your own computer.
