Filestay
Free file tools that never upload your files
Convert HEIC, compress images to an exact KB target, make passport/visa photos, merge PDFs and more — all processed on your device via WebAssembly. No signup, no limits, works offline.
I'm a frontend dev and CS teacher. I got tired of pointing people to upload-based converters with limits and upsells, so I built file tools that run entirely in the browser: WASM codecs (libheif, MozJPEG, etc.) inside Web Workers, static hosting, no backend at all.
