Hey Product Hunt! I built ConvertIt because every online file converter — from Zamzar to CloudConvert — uploads your files to their servers. For personal photos, videos, and sensitive documents, that didn't feel right. ConvertIt runs entirely in your browser using WebAssembly and Canvas APIs. There is no backend. Your files literally never leave your device. It handles almost any format: images (PNG, JPEG, WebP, AVIF, HEIC), video (MP4, WebM, MOV), audio (MP3, WAV, FLAC), PDFs, and SVGs. Would love your feedback! Happy to answer any questions about how the ffmpeg.wasm setup works or the architecture. Also check out ShrinkRay (my file compressor) — same privacy-first model!
