Convert, compress, trim, mute, resize, reverse, and extract audio from videos — powered by FFmpeg WebAssembly. All processing happens in your browser.
Every tool runs in your browser — files never upload anywhere.
Toolspace runs FFmpeg (compiled to WebAssembly) directly in your browser. FFmpeg is the same production-grade transcoder inside VLC, HandBrake, and countless streaming platforms. First visit downloads ~30 MB of the FFmpeg core (cached forever); after that, every tool runs offline.
Every combination that FFmpeg supports: MP4, MOV, MKV, AVI, WebM, FLV, plus audio-only conversions (MP3, WAV, AAC, FLAC, OGG). Video-to-GIF and video-to-audio extraction are also supported.
Roughly 30-60 seconds per minute of source video on a modern laptop. Long videos (over 30 minutes) may hit browser memory limits — use the Trim tool first for those.
No. Downloading videos from third-party platforms typically violates their terms of service, and browser sandboxing prevents it anyway. Toolspace focuses on video files you already have.
Toolspace uses FFmpeg's default CRF 23 for H.264 — visually indistinguishable from the source in normal playback. For master-quality output, target lossless codecs like FFV1 or ProRes.
Native FFmpeg uses your CPU's SIMD instructions and (often) hardware acceleration. WebAssembly FFmpeg is about 2× slower but gives you full privacy, zero installation, and no upload wait. For short clips it's a great trade-off.
