Convert Common Video Formats — Free

Received a MOV file you cannot open? Need to turn an MKV into MP4 for your phone? Klipa's free online video converter handles the common video formats so you never have to worry about compatibility. The conversion runs entirely on our servers, keeping your device free and your workflow fast.

Beyond simple format changes, converting to MP4 ensures your video plays smoothly on virtually every device and social platform. Want to go further? Compress the output to save space, or add AI subtitles before publishing.

How to Convert a Video Online

Step 1

Upload Your Source Video

Drag and drop a file in a common format — MP4, MOV, AVI, MKV, WebM, FLV, WMV, or 3GP. Up to 500 MB without an account, more with a free account and up to 5 GB on Pro. If the file is large, compress it first.

Step 2

Pick Your Target Format

Choose from MP4, WebM, MOV, AVI, or MKV. MP4 is the safest bet for universal compatibility, and WebM is ideal for web embedding. To make an animated GIF, use our dedicated GIF tool.

Step 3

Download the Converted File

Conversion usually completes in under a minute. Download the file directly or continue editing — for example, trim it or resize it for social media.

UNIVERSAL COMPATIBILITY

Frequently Asked Questions

Input: MP4, MOV, AVI, MKV, WebM, FLV, WMV, 3GP. Output: MP4, WebM, MOV, AVI, MKV. (For GIF, see our dedicated tool.)
When the input codec is already compatible with the target format, the video is copied with no loss when the codec is compatible. Changing codec (for example to WebM) re-encodes the video, so there is slight recompression.
Yes! MOV to MP4 is our most popular conversion. The result is compatible with all devices and social platforms.
The limit depends on your plan: 500 MB without an account, more with a free account, and up to 5 GB on Pro.
The converter outputs video; for an animated GIF use our dedicated GIF tool (choose the duration, width, and frame rate).
The time depends on the file size, duration, source codec, and chosen format.
Burned-in subtitles are kept (they are part of the video). Separate subtitle tracks are not carried over: the converter keeps only the video and one audio track.
Convert your format here first, then use our video resizer to adjust the resolution. Or compress to lower the bitrate instead.
No, conversion only changes the container format and codec without altering the content. The duration stays the same. To modify the content itself, use our video cutter before or after converting.
