Quick Share is a file-sharing service designed to make transfers between devices fast, simple, and privacy-conscious. Its browser-based tools let users send files without installing an app, while downloadable versions are available for Android, iOS, Windows, macOS, and Linux. On a shared local Wi-Fi network or LAN, devices can transfer files directly, without uploading them to external servers or requiring internet access. The service also offers Cloud Transfer, which lets users share files through links with people anywhere. Additional tools create share links for text, files, images, and videos, and provide QR codes for accessing links.

Quick Share highlights cross-platform compatibility, device discovery, encrypted transfers, and a privacy-first approach. Local network transfers are free and unlimited, with no registration or artificial file-size limits; actual limits depend on device storage and network conditions. Cloud Transfer has a free tier for files up to 1 GB and a Premium subscription for $2.99 per month, offering transfers up to 5 GB, custom expiration periods, password protection, and an ad-free experience.
