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 skinning and blendshapes survive?

Yes. The FBX is byte-identical.

Does FBX include textures?

FBX can embed textures or reference them. If your export is set to embed, the file is self-contained. Otherwise zip the textures with it.

Are animation curves preserved?

Yes. Keyframe data and curves stay intact.

Can Unity and Unreal import this directly?

Yes. Both engines import FBX natively.

How to send an FBX file.

FBX is the format that 3D pipelines pass around: rigs, blendshapes, animation, materials, all in one container. The files get large fast. quik.space stores the FBX byte-for-byte and gives the recipient a clean download for Maya, Blender, Unity, or Unreal.

What is a FBX 3D model?

FBX 3D model files use the .fbx extension with no single standard MIME type. The format sits in the 3d category. Typical files run 5 MB - 1 GB, which is well above what most email services will accept as an attachment.

Why you can’t email a FBX 3D model

FBX is the rig-and-animation interchange format. Rigged character FBX files with skinning, blendshapes, and animation can easily hit 500 MB. Email caps make this impossible.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 FBX 3D model

quik.space stores the FBX byte-for-byte. Skeleton, skinning, blendshapes, animation curves, materials, all survive. The recipient imports into Maya, Blender, Unity, Unreal, or any DCC. The share page does not render 3D scenes inline. The recipient downloads the file and opens it in the matching DCC.

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.

Common use cases

Send a rigged character FBX to an animator
Hand off motion-capture FBX to a cleanup artist
Share a hard-surface FBX with an environment artist
Pass an animated FBX to a Unity or Unreal engine team
