This Open Source Tool Sends Large Files Directly Browser to Browser **[It's Foss](https://daily.dev/sources/itsfoss)** · 4 min read · 0 upvotes · 0 comments ## Summary CheezyPizza is an open source, browser-based peer-to-peer file transfer tool built on WebRTC, forked from FilePizza. It addresses key limitations of its predecessor by supporting large files (10 GB+), adding pause/resume functionality backed by OPFS or IndexedDB, flow control via WebRTC data channel watermarks, and SHA-256 integrity verification. All transfers are encrypted with DTLS and require no account or server. A real-world test transferring a 7 GB ISO confirmed the pause/resume feature works on the downloader side, though the uploader must keep their browser tab open for the transfer to continue. ## Full article daily.dev links to this article rather than hosting it.
