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 Firefox Send

Firefox Send is gone. quik.space picks up the same job — and brings the moderation story Send was missing.

A short history

Mozilla launched Firefox Send in 2017 as a free, anonymous, link-based, end-to-end-encrypted file-sharing service. Files expired after one download or a set time window. Open source. No account required. Limit 2.5 GB free, 1 GB without signin. Mozilla shut it down in 2020 after a wave of malware abuse — the e2e encryption that protected users also made server-side malware scanning impossible, and the team did not have the moderation tooling to keep up.

What quik.space carries forward

Anonymous use — no account required.
Link-based delivery — share a URL, recipient downloads.
Time-limited by default — 72 hours, with a paid 30-day extension instead of Send's one-download trick.
Open and friendly — there are no dark patterns trying to push you into a subscription.

What quik.space does differently

The single biggest difference: quik.space ships with moderation infrastructure from day one. Every upload's SHA-256 hash is checked against a blocklist (NCMEC-aligned for CSAM, plus known malware hash sets). Each share page exposes a report endpoint. Verified bad content triggers automated takedown within minutes.

The trade-off: quik.space does not offer client-side end-to-end encryption today. Files are encrypted in transit and at rest by the storage provider, but platform operators could read content if compelled by a valid legal request. This is the price of having a working abuse story. For genuinely secret material, encrypt locally before uploading.

The other shift: quik.space is a sustainable, paid product. Free for small one-shot sends, paid for anything beyond. Firefox Send was a Mozilla side project funded by donations. quik.space is built to outlive its founder's patience.

Bottom line

If you missed Firefox Send, quik.space is the closest thing still standing. Same job, modern stack, abuse-handled. For maximum secrecy, you give up the comfort of e2e — but you get a service that exists tomorrow.
