You upload, anyone can download

How it works

Three steps. No waiting.

Upload starts, link is ready. Your friend downloads live.

Drop your file

Drag & drop or click to upload. Any file type. Up to 100 GB. Encrypted in your browser before it leaves.

Get link instantly

The shareable link appears the moment you drop a file — before the upload even finishes. Share it right away.

Friends download live

Your friend opens the link and sees your upload progress. Download starts automatically. Both happen at once.

Everything you need

Built for speed, security, and simplicity

Instant Link

The shareable link appears the moment you drop a file. Before the upload even finishes.

Live Transfer

Your friend sees upload progress in real-time. Download starts automatically when ready.

Up to 100 GB

Any file type. Images, videos, PDFs, archives, code, binaries. No restrictions.

Auto-deletes

Files are automatically purged after your chosen TTL. Zero cleanup, zero traces.

Private & Secure

Files can only be accessed with the exact link. No browsing, no listing, no guessing.

E2E Encrypted

AES-256-GCM encryption in your browser. Not even we can see your files.

AI Agent Ready

Ships with an MCP server for Claude. Point any AI agent to /llm.md for instant API docs.

CLI First

One curl command to upload. One to download. Works with wget, Python, Node, and anything that speaks HTTP.

Multi-Download

Share one link with a hundred people. Everyone downloads the same file. Refresh works too.

API Reference

Two endpoints. That's the entire API.

POST

/api/upload

Upload any file. No size limit. Returns a download link.

curl -F "file=@report.pdf" \
ultra.egomonk.com/api/upload

GET

/api/dl/{id}

Download a file by UUID. Forced download, never renders.

curl -OJL \
