The tool this guide uses
Anything but Original forces a re-encode.
Quality, if a re-encode is needed
Drag files here, or
Converted to MP4 on your device. The converter itself is a 9.8 MB download, once.
Ready. Runs locally on your device.
Your files stay on your device. The tool works directly in your browser, using your device to process your files. Nothing is sent to our servers, and we never receive, store, or see your files or figures.
The short answer
- Quick conversions with no install, and no upload: a browser-based converter, such as the one above.
- Heavy work on a computer, such as re-encoding long 4K video: HandBrake, a free desktop app.
- A file format nothing else opens: an online service such as CloudConvert, within its free allowance.
- Something to play and occasionally convert: VLC, which you may already have.

Online service figures are from each service’s own pricing and security pages as they read on 11 September 2026.
Each option, briefly
Reembun. Converts in your browser, so the video never leaves your device, on a phone as well as a computer. When the formats allow, it repackages the video without re-encoding, which takes seconds even for a large file. It converts to MP4, WebM, MKV, MOV, AVI and GIF, and audio to MP3, M4A, WAV, AAC, OGG and FLAC. Full re-encoding on a phone is slow, and files much above 2 GB may not fit in a browser tab’s memory.
CloudConvert. Handles far more formats than video, including documents, ebooks and archives, and offers an API. The free plan allows 10 conversions a day with files up to 1 GB. Its security page says each conversion runs in an isolated container and files are deleted immediately after processing.
FreeConvert. A straightforward online converter. Free users get 20 conversion minutes a day and up to 5 minutes per file, without an account.
HandBrake. A free, open source desktop app for Windows, Mac and Linux, and the standard choice for re-encoding video with full control over quality and size. It runs on your own computer, so nothing is uploaded, and a desktop processor is far faster than a phone for heavy work.
VLC. The free, open source media player that opens almost anything. Its convert option handles simple conversions locally, though with fewer controls than HandBrake.
How to choose
- Is the video personal? Family footage, recordings from inside your home or a meeting are worth keeping on your device. Use a browser-based converter or a desktop app.
- Is it big and does it need re-encoding? For a long 4K video, a desktop app on a computer is fastest.
- Is the format unusual? For something only a specialist converter handles, an online service is the practical route.
- Are you on a phone with no app? A browser-based converter works without installing anything.
How this comparison was made
The limits and file handling for online services come from their own pages, read on 11 September 2026. HandBrake and VLC are described from their public product pages and long-standing features. The Reembun details come from how its converter works, as described on its own tool pages. We have not run a speed test across all five on the same files.
Common questions
Which free converter is fastest?
It depends on the job. Repackaging a video into another container, such as many MOV to MP4 conversions, is fastest on your own device, because there is no upload or download. Fully re-encoding a long, high resolution video is fastest on a powerful computer running a desktop app, or on a server.
Which ones keep my video private?
The ones that never send it anywhere: desktop apps such as HandBrake and VLC, and browser-based converters such as the one above. Online services upload the video to their servers and delete it after processing, which is reasonable but still means a copy leaves your device.
Is there a converter with no daily limit?
Desktop apps have none, and neither does the converter above, because none of them use a server. Online services limit free use because every conversion costs them processing time.
