Use case · Large files
Send large files for free, no sign-up, no speed cap
Email attachments often stop at 25MB, and cloud drives want an account and an app. cpcp works in the browser: up to 100MB per file, 20 files, and 200MB per parcel. There is one free tier today; transfers are not throttled.
How to send
- Open cpcp on the sending device, choose Files, then drag files in or pick them.
- Seal the parcel to get a 6-digit pickup code. The recipient can also scan the QR code.
- Enter the code on the receiving device and download each file. It expires after one hour and can no longer be picked up; storage is cleared within 10 minutes after that.
