HandBrake
FreeThe open-source video transcoder — compress and convert entirely offline
Open Source No Ads No Tracking Offline No Sign-up Cross-platform
Convert video from nearly any format to MP4, MKV or WebM with rich built-in presets — shrink size, change resolution and batch process entirely on your machine, no uploads, no watermark.
Why we picked it
Built on mature tools like FFmpeg, x264 and x265, HandBrake wraps complex transcoding into ready-to-use presets — pick something like "Phone" or "1080p" and you're done. Power users can still tune the encoder, bitrate and filters by hand.
Everything runs locally: no server uploads, no watermark, no subscription. Fully open source with no ads and no telemetry, it's the dependable choice for compression and format conversion.
