7 Best Free HD Video Converters for Windows and Mac (2026 Guide)

Back in 2010, this page offered a license giveaway for Xilisoft HD Video Converter. That promotion ended more than a decade ago, so we’ve completely rebuilt this guide around what actually matters today: the best ways to convert HD and 4K video — most of them completely free.

Shutter Encoder (free) is an FFmpeg front-end popular with video editors, exposing professional options (ProRes, DNxHD, LUTs, loudness normalization) that HandBrake hides while staying friendlier than raw command line — start here if you need broadcast formats. Wondershare UniConverter (~$40/yr) is the best-known commercial pick, paying for convenience: trimming, subtitle tools, a DVD ripper and batch compression in a clean interface (the free trial watermarks output). Movavi Video Converter (~$50/yr) is beginner-friendly and fast on modest hardware; its “SuperSpeed” mode remuxes files without re-encoding when the codec already matches, finishing in seconds with zero quality loss. For small files when you can’t install anything, CloudConvert and FreeConvert work in-browser — but never upload private footage to a third-party server, and free tiers cap file size (typically 1 GB). If you also rip discs, see our roundup of the top free DVD ripping software.

What Happened to Xilisoft?

Xilisoft’s converters were popular in the 2008–2014 era, but the software hasn’t kept pace with modern codecs and hardware encoding, and the licensing giveaways that made it attractive are long gone. There’s no reason to hunt for old Xilisoft license keys today — key-generator sites that claim to offer them are a common malware vector. Free, actively-maintained tools like HandBrake are simply better now.

Which Format Should You Convert To?

MP4 with H.264 is still the universal choice — it plays on everything. Use H.265/HEVC when file size matters more than compatibility (roughly half the size at the same quality), and AV1 if you’re uploading to YouTube or targeting modern devices, since it compresses even better and is royalty-free. If you want just the audio, see our walkthrough on extracting audio as MP3.

Frequently Asked Questions

Is HandBrake really safe?
Yes — download it only from handbrake.fr, the official site. Fake download portals bundling adware are the main risk.

Can I convert video without quality loss?
True lossless conversion only happens when you change the container without re-encoding (remuxing). Any re-encode loses some quality; a quality factor around RF 18–22 in HandBrake keeps the loss invisible.

What’s the best free video converter overall?
HandBrake for nearly everyone — free, maintained, GPU-accelerated, with great presets. VLC is the quickest if it’s already installed.

Do I still need a DVD ripper?
HandBrake rips unencrypted DVDs; encrypted commercial discs require additional libraries, and the legality of ripping them varies by country — check your local law.

Which format is most compatible?
MP4 with H.264 — it plays on virtually every device, browser and player.
