Hey Product Hunt! 👋 I built ShrinkRay because every online compressor I found uploads your files to their servers. For tax PDFs, personal photos, and sensitive documents, that didn't feel right. ShrinkRay runs entirely in your browser using WebAssembly — there is no backend. Your files literally never leave your device. It handles almost any file type: images, video, audio, PDFs, 3D models, SVGs, text/code, and anything else via gzip. Would love your feedback! Happy to answer any questions about how the ffmpeg.wasm setup works or the architecture.
