Hey Product Hunt 👋 I kept needing to convert a video to MP3 or compress a photo to under 20 KB for an exam form, and every online converter I tried wanted me to upload my file to a server I'd never heard of. I didn't want my stuff on someone else's disk. So I thought: FFmpeg can do all of this. Why not run it in the browser? MediaShift runs FFmpeg compiled to WebAssembly — the same FFmpeg, just sandboxed in a tab: • 22 output formats — MP4, WebM, MOV, MKV, GIF, MP3, WAV, FLAC, PNG, JPG, WebP, AVIF and more • 60+ input formats — drop a file or a whole folder, each type converts to its own format • Target-size compression — fit a photo under 20, 50 or 100 KB for online forms. It binary-searches JPEG quality and only scales down when quality alone can't fit • Exam form tools — SSC, IBPS and UPSC photo and signature presets with exact pixel sizes • Batch + ZIP download — convert everything, download one ZIP that keeps your folder structure No upload, no server, no account, no watermark. After the first visit it works offline. I'd love to hear what format you convert most often!
