The promise · verifiable
Your files never leave your browser. That is the whole product.
Most online image and PDF tools work by uploading your file to a server, processing it there, and sending the result back. That works, but it means a copy of your image, your contract, your receipt sits on a stranger's disk. Sometimes briefly. Sometimes for days "for your convenience."
OmegaPix runs every tool inside your browser using WebAssembly. The same C++ image and PDF libraries the upload-based tools run on their servers, except they run in the tab you have open. Open DevTools, Network, during a compression and you will see zero outgoing requests carrying your file. That is the no-upload promise, verifiable.
There is no account, no email capture, no cookie banner. No telemetry on your files. The page itself is plain HTML and JavaScript, viewable, auditable, fork-able. The trust posture is structural, not promised.
No Fetch/XHR requests
Your file never makes an outgoing request: compress, convert, anything.
Open DevTools → Network → filter Fetch/XHR.
Use any tool. This pane stays empty.
Code modules (workers, WASM decoders) do load once and cache. The Fetch/XHR filter strips those out so you see only what would carry your file, which is nothing.
