Hey everyone! I'm Guilherme, a solo developer based in Portugal.
The inspiration came from two frustrations: WeTransfer compresses my videos down to 1080p even when I export at 4K, and Google Drive sells your data while eating my storage space. So I decided to build something that does both things right — no compression and EU privacy.
The Upload Method was the hardest part to get right. I spent weeks reverse-engineering how TikTok re-compresses videos and testing different MP4 structures. The breakthrough was realising that moving the moov atom before mdat (the fast-start flag) plus preserving colour tags makes their CDN treat the video as web-optimized instead of re-encoding it from scratch. Now creators can edit in TikTok Studio, download the edited version, run it through Upload Method again, and post without losing quality.
Tech stack is Cloudflare Workers for the backend, vanilla JS on the frontend with no frameworks, D1 for SQLite and R2 for storage. Everything runs on Cloudflare's edge network across Europe.
Would love your feedback especially on the Upload Method — does it work well for your workflow?
