Video files refuse to be compatible. Your phone records in one format, your smart TV wants another, the upload form wants a third, and the file you downloaded three years ago is somehow 40 GB for a two-hour movie. Sooner or later, every Windows user needs a converter.
The market around this need is full of traps: converter websites that barely work, "free" desktop apps that slap a watermark on your video or nag you to upgrade, and trial versions that convert the first two minutes and then stop. The honest tools are also free, and they are better than the ones fishing for your card number.
Here are four worth keeping on your machine, along with what each one costs you in convenience.

HandBrake: the default answer
HandBrake is the open-source converter most people should start with, and most people can stop there too. It converts nearly anything into MP4 or MKV, using modern encoders like H.264, H.265, and AV1, and it leans on your GPU when your hardware supports it, which makes a real difference in speed.
The strengths:
- Presets for common targets: web, devices, specific resolutions
- Solid control over quality, with sensible defaults when you do not care
- Batch queueing for converting a folder of files overnight
- Free, open source, no watermarks, no upsells
The trade-off: output formats. HandBrake produces MP4 and MKV and that is basically it. It is a tool for making playable, well-compressed files, not for converting into odd containers or pro formats. Also, its interface is denser than it needs to be; the preset list helps, but the front page still looks like it was designed by and for engineers.
Shutter Encoder: the professional's freebie
Shutter Encoder comes from a video professional, and it shows. Under the hood it is a friendly face on the same engines broadcasters use, which means it speaks formats HandBrake has never heard of: ProRes, DNxHD, and a long tail of production codecs, plus the usual consumer stuff.
The strengths:
- Enormous format support, including professional intermediate codecs
- Extras that go beyond converting: cutting without re-encoding, subtitles, audio extraction, image sequences
- Available in a portable version, so it runs from a USB stick
The trade-off: it is French-developed and it shows in small ways. The interface packs a lot of options into a small window, the English translation is serviceable rather than polished, and the sheer number of functions can be intimidating. If you just need an MP4, HandBrake is simpler. If you have a weird file or a pro workflow, Shutter Encoder is the free tool that will not blink.
VLC: the converter you already have
If you have VLC installed, you already own a converter. Under the Media menu sits a Convert/Save function that transcodes files into a handful of common formats and can even rip the audio out of a video.
The strengths:
- Already installed on half the computers on earth
- Handles almost any input file, because VLC plays almost anything
- Zero learning curve for simple jobs
The trade-offs, and they are real: VLC's conversion output settings are crude, there is no batch queue worth using, quality control amounts to picking a profile, and the feature is buried in a menu most users never open. Think of VLC's converter as the scissors in your kitchen drawer. It works, you already have it, and if you find yourself converting videos every week you should get a proper pair.
Clipchamp: for people converting to edit
Clipchamp, which Microsoft now owns and bundles with Windows, is a video editor first and a converter second. You import a file, and you can export it in different resolutions and aspect ratios while you are at it. Its real trick is reframing: turning a horizontal video into vertical for Shorts or TikTok, or square for a feed.
The strengths:
- Editing and converting in one browser-based app
- Simple aspect-ratio presets for social media
- Comes preinstalled on Windows 11
The trade-offs: the free tier has limits on export quality, cloud processing means upload and download time you do not spend with desktop tools, and for a straight conversion of a large file it is slower than HandBrake by a mile. Clipchamp earns its place only when the conversion is part of an edit.
Which one should you pick?
- General purpose, every week: HandBrake
- Weird formats or pro codecs: Shutter Encoder
- One-off job, nothing new to install: VLC
- Converting as part of a social edit: Clipchamp
All four are free in some form, and none of them will watermark your output if you pick the right one. Start with HandBrake and only reach further down this list when it says no to a file.
