Editor's verdict
After converting the same batch of clips in every tool, the CoolUtils Total Movie Converter is our top pick. It reads AVI, MKV, MOV, FLV, WMV, MTS and more, exports to AVI, MPEG, WMV, FLV or a ready device preset, processes whole folders at once, runs from the command line for automation, and keeps every file on your own machine. One-time price, no subscription.

Quick answer: The best video converter in 2026 is the CoolUtils Total Movie Converter. Install it, add a clip or a whole folder, choose an output format (AVI, MPEG, WMV, FLV) or a device preset for iPhone, iPad or Xbox, and click Start. It converts in batch, runs from the command line for automation, can extract audio and resize or rotate clips, and works offline for a one-time $29.90 — no subscription, no upload.
A video file is only useful if your player, phone or editor can open it. The moment a MKV will not play on your TV, an AVI chokes your phone, or you need to feed a folder of clips into one editor, you need a converter — and not every tool handles a folder of 500 files, device presets or an offline, automated workflow.
We screened 10 desktop and online video converters, then put the 6 most capable through the same test: convert a single MKV to MP4 and AVI, convert a folder of 50 clips in one run, prepare a video for an iPhone using a preset, extract the audio track from a movie, and automate a conversion from the command line. Here is how they ranked.

CoolUtils Total Movie Converter
Windows · 70 MB · $29.90 one-time
Best overall & best for batch + automation
The CoolUtils Total Movie Converter was the only tool in our test that combined wide input coverage, true folder-level batch conversion, ready device presets and command-line automation in one $29.90 desktop app. It reads AVI, FLV, MKV, M2TS, MOV, VOB, SWF, MPEG, MPEG4, ASF, WMV, 3GP, MOD and DivX and writes AVI, MPEG, MPG, WMV or FLV — or a one-click preset sized for iPad, iPhone, Apple TV or Xbox.
Two things put it on top. First, the device presets and editing tools: rotate, resize and cut clips, merge several into one, adjust bitrate and frame rate, de-interlace, or extract the audio track to a separate file. Second, the command-line build lets you wire conversions into a .bat file or a scheduled task — convert every clip dropped into a folder overnight, untouched by a human. Everything runs offline, so footage never leaves the machine. The trial is 30 days with no credit card or email.
Pros
- True batch conversion of whole folders of clips
- Wide input list plus AVI, MPEG, WMV, FLV output and device presets
- Command-line build for automation and servers
- Rotate, resize, cut, merge, extract audio; offline; one-time $29.90
Cons
- Windows only (no native Mac build)
- Output set focuses on AVI, MPEG, WMV and FLV containers
- No free tier (but a 30-day full trial and a one-time price)

HandBrake
Windows / Mac / Linux · free, open-source
Best free open-source converter
HandBrake is the go-to free, open-source ripper and converter, with excellent H.264/H.265 encoding and a long list of device presets. It is cross-platform and has a command-line interface for scripting. The catches: it outputs only MP4, MKV and WebM, there is no simple drag-a-folder batch in the GUI (you build a queue file by file), and it cannot keep certain legacy formats. Brilliant for quality-focused MP4/MKV work; fiddly for mixed bulk jobs.
Pros
- Free and open-source
- Top-tier H.264/H.265 encoding and presets
- Cross-platform with a CLI
Cons
- Output limited to MP4, MKV, WebM
- No easy folder-batch in the GUI (queue by hand)
- Steeper learning curve for newcomers

Any Video Converter
Windows / Mac · freemium
Best easy GUI for casual jobs
Any Video Converter handles a broad range of inputs and outputs with a friendly interface, batch list and device profiles, and the free version covers many everyday conversions. The trade-off is the freemium model: the installer pushes extras, some outputs and faster speeds sit behind the Ultimate upgrade, and free output can carry limits. Fine for the occasional convert; watch the upsell prompts during setup.
Pros
- Wide format support and device profiles
- Simple batch list interface
- Free tier covers basic jobs
Cons
- Installer bundles extra offers
- Best features locked behind paid Ultimate
- Free output can be limited
4
Freemake Video Converter
Windows · freemium
Best beginner-friendly interface
Freemake is one of the simplest converters to learn, with a clean interface, many input formats, ready presets and batch support. The big caveat is that the free version stamps a Freemake logo and intro/outro branding onto your output unless you pay to remove it, and it is Windows-only. Approachable for a first-timer, but the watermark makes the free tier unsuitable for anything you will share.
Pros
- Very easy for beginners
- Lots of input formats and presets
- Batch conversion built in
Cons
- Branding watermark on free output
- Windows only
- Some features require the paid pack

VLC Media Player
Windows / Mac / Linux · free
Best if you already have it installed
VLC plays nearly anything and quietly doubles as a converter through its Convert/Save dialog, so it is free and already on most machines. But conversion is not its focus: the dialog is clunky, profiles are limited, batch handling is awkward, and results vary. It can extract audio and run from the command line for the determined. Useful in a pinch when it is the only tool to hand; not built for serious or bulk conversion.
Pros
- Free and plays almost every format
- Already installed for many users
- Can extract audio and script via CLI
Cons
- Clunky, hidden conversion workflow
- Limited output profiles
- Poor for batch jobs

CloudConvert
Online · subscription
Best for a stray file on any device
CloudConvert handles a huge list of formats in the browser, so nothing is installed and it works on any OS. The trade-offs are real for video: every file is uploaded to their servers, free minutes and file size are capped, large clips and steady use need a paid plan, and a slow connection stalls big uploads. Its API can automate jobs for developers. Handy for a single file; the wrong tool for confidential footage or bulk work.
Pros
- Nothing to install, any OS
- Very wide format list
- Developer API for automation
Cons
- Files uploaded to the cloud
- Minutes and file-size limits; subscription
- Slow for large clips and no offline use
How to convert a video (or a whole folder)
This is the exact workflow we used with the number-one tool. A single clip takes under a minute; a folder of hundreds is one click more.
- Download and install Total Movie Converter. Grab the 70 MB installer from CoolUtils and run it. The 30-day trial needs no credit card or email.
- Add your videos. Point it at a single clip or select a whole folder — the file tree lets you tick exactly what to convert. Nothing is uploaded; everything stays on your PC.
- Pick the output format or device. Choose AVI, MPEG, WMV or FLV from the toolbar, or a ready preset for iPad, iPhone, Apple TV or Xbox. Use the built-in player to preview a clip first.
- Set options. Rotate, resize or cut the clip, adjust bitrate and frame rate, de-interlace, extract the audio track, or just keep the defaults.
- Click Start. The whole batch converts at once and the originals are left untouched, with the source folder structure preserved in the output.
Automating it from the command line
The differentiator for power users: the command-line build converts without opening the window, so you can script it. A line like the one below, dropped in a .bat file and scheduled, turns every clip in a folder into AVI files overnight.
VideoConverter.exe "C:\In\*.mkv" "C:\Out" -cAVI -log log.txt
Just need a quick one-off convert? For a single clip on any device, CoolUtils also offers
free online converters. For batch work, device presets, audio extraction and offline privacy, the desktop Total Movie Converter is the tool that scales.
How we tested
We do not rank on spec sheets alone. Every tool ran the same five-part job on the same Windows 11 machine, using identical source files:
- MKV to MP4 and AVI — one movie converted to common formats, checking quality and sync.
- Folder batch — 50 clips converted in a single run.
- Device preset — a clip prepared for iPhone playback with one click.
- Audio extraction — pulling the soundtrack out of a video to a separate file.
- Automation — the same conversion driven from the command line or a queue.
Scores weight what matters for real conversion work: output quality and format coverage (30%), batch and automation (30%), device presets and editing extras (20%), and price and privacy (20%). Pricing was checked on each vendor's site in June 2026.
Who needs a dedicated video converter?
Anyone who has to get footage into the right shape at scale: editors normalising mixed clips before a project, anyone preparing video for a specific phone, TV or console, teams archiving recordings, or a power user automating a conversion pipeline. For all of those, the CoolUtils Total Movie Converter does the most for the least — one price, offline, scriptable. New to the basics? Start with our video formats reference.
Frequently asked questions
How do I convert MKV to MP4 or AVI?
Install a desktop converter such as the CoolUtils Total Movie Converter, add your MKV clip, choose AVI (or another supported container) and click Start. It keeps quality and audio sync intact, works offline and needs no subscription — a one-time $29.90 licence.
Can I batch convert a whole folder of videos at once?
Yes. Total Movie Converter is built for batch work: point it at a folder, tick the clips you want, pick an output format and convert them all in one run. The original folder structure is preserved, and it can also run from the command line for unattended jobs.
How do I convert a video for my iPhone?
Open the clip in Total Movie Converter and choose the iPhone device preset (presets for iPad, Apple TV and Xbox are there too). It sizes and encodes the video for that device automatically, so it plays without a codec error — no guesswork about resolution or bitrate.
Is there a video converter with command-line or automation support?
Yes. Total Movie Converter ships a command-line build, so you can script conversions in a .bat file or a scheduled task and process folders automatically on a server — something online converters and most simple GUI tools cannot do.
Are online video converters safe for private footage?
Browser-based converters upload your clip to a third-party server, which is a poor fit for private or unreleased footage and runs into file-size and time limits. A desktop converter like Total Movie Converter processes everything locally, so your video never leaves your machine.
Does it work offline, and is it a subscription?
Total Movie Converter runs fully offline and is a one-time $29.90 purchase, not a subscription. There is a 30-day free trial with full functionality and no credit card or email required.
