Frequently asked
Why is FileTransfer.io's free limit so big?
Their model is closer to a freemium funnel: free is generous so casual users convert to Pro for password protection and longer retention. quik.space's model is pay-per-action with a small free tier that is never thrown away.
Is FileTransfer.io trustworthy?
It is a small, focused operator with a clean privacy posture. There is no public AI-training commitment, but the service has been stable for years and the UI does not push aggressive ads.
Can quik.space match the 21-day retention?
Yes, with a $2 extend per file. The first 72 hours are free, then $2 gets you another 30 days. Renewable indefinitely.
Does FileTransfer.io have an API?
Not a documented public API. Like quik.space, it is primarily a browser product.
