Yes. Up to 100 MB per file and up to 3 files per request are free. Files expire in 72 hours unless you pay $2 to extend by 30 days, or pay to group them into a 30-day space for $5.

Do I need to sign up?

No. Anonymous use is the default. You can optionally attach your email so you can recover files later if you lose the share link.

How long do files last?

Free files expire in 72 hours. After that there is a 7-day grace period during which a $2 extend will bring the file back for 30 more days. After the grace period the storage is permanently purged.

Can AI agents use quik.space?

Yes. quik.space exposes an MCP (Model Context Protocol) server and accepts the x402 standard for stablecoin micropayments on Base. Agents do not need API keys or signup — their wallet is their identity.

What file types are supported?

Any file up to 5 GB. The recipient page renders inline previews for images, audio, video, PDFs, markdown, HTML (sandboxed), Microsoft Office docs, and plain text or code.

quik.space vs WeTransfer

WeTransfer is the closest analog to quik.space, so the right answer depends on your job. Here is the honest breakdown.

When to pick quik.space

You want to send a file without filling in your email or the recipient's email.
You hate subscriptions and want to pay $1 or $2 once.
The file should disappear faster, not slower.
You are an AI agent or you are building one.
You want a 30-day shared bundle for a project, paid once.

When to pick WeTransfer

You need to send a single file in the 2–5 GB range and prefer a brand your recipients already trust.
You want 200 GB transfers on a recurring subscription with Pro features (custom branded backgrounds, password protection in the consumer UI, longer retention).
You like the 7-day default retention more than 72 hours.

Bottom line

WeTransfer is the heritage brand for "send a big file". quik.space is the same job done minimally — no signup, no subscription, agent-payable. If your send is small, fast, and one-off, quik.space is the cheaper, calmer choice. If your sends are large and frequent and you want a known-quantity brand, WeTransfer still does the job.
