Lossless Copy or Smart Re-Encode, Depending on Your Codec

Converting a video online means changing its file format — for example a MOV into an MP4, or an AVI into an MKV — without installing anything: you drop the file, Klipa automatically detects whether it can copy it losslessly or needs to re-encode it, and you get the result back within minutes.

The format a video file arrives in is rarely a choice: an iPhone records in MOV, an old camcorder or screen recorder produces AVI or WebM, an export from professional editing software lands in MKV. Klipa's converter absorbs those differences in one step: five output formats (MP4, WebM, MOV, AVI, MKV), and on input, legacy formats too — WMV, FLV and 3GP.

How to Convert a Video Online

Step 1

Upload Your Video

Drag in a file in a common format — MP4, MOV, AVI, MKV, WebM — or even an older FLV, WMV or 3GP file. Up to 500 MB with no account, 1 GB with a free account, 5 GB on the Pro plan.

Step 2

Pick the Output Format

MP4 for universal compatibility, WebM for the web, MOV for Apple editing workflows, AVI or MKV depending on your needs. Klipa detects your file's codec and decides on its own between a lossless copy and a re-encode.

Step 3

Download the Result

A lossless copy (codec already compatible) is near-instant; a re-encode (HEVC, ProRes, codec change) takes a bit longer, depending on file size. Grab the file, never watermarked, or chain it straight into another Klipa tool — compression, subtitles — without re-downloading anything.

Why Convert With Klipa

🔄

Five common formats

MP4, WebM, MOV, AVI and MKV on output — the formats that cover nearly every sharing and editing need.

🎬

Lossless when possible

When the source codec already fits the target container, Klipa copies the stream as-is: no recompression, no quality loss.

Never watermarked

Unlike some other video tools, the converter never stamps a logo on the result, even with no account.

🌐

No software to install

Everything happens in the browser: no software download, no codec settings to figure out beforehand.

Use Cases

iPhone or Mac Video to MP4

An iPhone records in MOV, sometimes in HEVC. Convert it to MP4 so it opens without issue on a Windows PC, an Android phone, or any social platform.

Legacy Files to a Modern Format

Camcorder footage in AVI, screen recordings in WebM, archives in WMV or 3GP: convert them to MP4 to play them on a current device and back them up for the long term.

Browser Screen Recordings

Chrome and Firefox save screen recordings as WebM. Convert to MP4 to share a tutorial, bug report, or demo with anyone, regardless of their device.

To MOV for Apple Editing

Final Cut Pro and iMovie work best with MOV. Convert your MP4 source footage to MOV before importing for a smoother editing timeline.

To WebM for a Website

A page background video needs to be light. WebM produces a smaller file than MP4 at comparable quality, which means a faster page load.

Frequently Asked Questions

Klipa converts videos to MP4, WebM, MOV, AVI or MKV. On the input side, it also accepts legacy formats like WMV, FLV and 3GP, automatically turning them into the output format you pick. For an animated GIF or audio-only file, use our dedicated tools instead.
Yes — conversion is free, watermark-free, and works without creating an account. A free account simply raises the file size and duration you can convert; the Pro plan lifts those caps further for heavier workloads.
It depends on the change you're making. If your video's codec already plays inside the new container, Klipa copies it as-is, with zero quality loss. If the codec itself must change (for example to WebM), a light re-encode happens — invisible to the eye at normal viewing quality.
The container (MP4, MOV, AVI...) is the file's wrapper; the codec (H.264, HEVC, VP9...) is how the picture is compressed inside it. Changing the container can happen without touching the picture at all; changing the codec always requires a re-encode.
Without an account, videos up to 500 MB and 5 minutes are accepted. A free account raises that to 1 GB and 20 minutes. The Pro plan goes up to 5 GB and 2 hours, built for large camera or drone footage.
Without an account, one conversion per day. A free account allows 3 conversions daily, and the Pro plan raises that to 30 per day — enough to process a batch without coming back each time.
No, never, on any tier. The converter never stamps a watermark on your video — unlike some other Klipa tools that reserve a clean export for paid accounts, conversion always produces a plain, ready-to-share file from the very first use.
Your video is processed on our servers, then deleted automatically: after 48 h if you have no account, after 7 days with a free account, after 30 days on the Pro plan. Nobody else has access to it in the meantime, and you can re-download it until it expires.
No, this converter only handles video-to-video conversion, never audio alone. To pull just the audio track as an MP3 file, use our dedicated audio extractor tool instead; for an animated GIF, our video-to-GIF tool is built specifically for that job.
Yes. WMV files (from Windows Movie Maker), FLV files (old Flash-era sites) and 3GP files (2000s camera phones) are all accepted as input and converted automatically into a modern format like MP4, playable on today's devices and platforms.

A Format Should Never Block Your Video

A video file in the wrong format should never block a share, an edit, or an upload. Klipa's converter handles common formats — MP4, MOV, AVI, WebM, MKV — plus legacy ones, with a lossless conversion whenever possible and never a watermark on the result. Need a specific pair?
