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.

Will compression level affect the file after upload?

No. FLAC compression is lossless; we store the bytes you uploaded. The recipient gets the same file.

Does the embedded album art survive?

Yes. FLAC metadata and embedded pictures are byte-identical.

Can the recipient stream FLAC inline?

Chromium and Firefox stream FLAC inline. Safari downloads only. Either way, the file is recoverable.

What about FLAC up to 5 GB?

$5 covers up to 5 GB. Most multi-album lossless archives fit. For full discographies, zip and pay $5.

How to send a FLAC file.

FLAC is lossless without the bloat of WAV, but it is still much bigger than MP3. Email won't carry an album rip. quik.space stores the FLAC byte-for-byte, Vorbis comment and album art included, and gives the recipient a clean download link.

Free up to 100 MB. No signup, no email needed.

No email means no recovery. If you lose this link, we can't get you back to this file.

What is a FLAC audio?

FLAC audio files use the .flac extension and the audio/flac MIME type. The format sits in the audio category. Typical files run 20 MB - 600 MB, which is well above what most email services will accept as an attachment.

Why you can’t email a FLAC audio

FLAC is lossless compressed. A 45-minute album is roughly 250 MB. A high-rate hi-res FLAC can run 600 MB. Email rejects anything above 25 MB.Slack, Discord, and most other workplace tools have similar caps, often around 1 GB for free tiers and with aggressive per-channel storage limits. Even when the file fits, it counts against the recipient’s mailbox quota forever.

How quik.space handles FLAC audio

quik.space stores the FLAC bytes intact. Metadata (Vorbis comment, embedded album art) survives. The recipient downloads the original and plays it in any lossless-capable player. The share page renders an inline HTML5 audio player, so the recipient streams the file before downloading the original.

The file lives for 72 hours by default and then enters a 7-day grace period. We do not train AI on your files. We do not share them with third parties. After grace, the bytes are permanently purged from storage. Read the full policy on privacy.
