Can I download or convert YouTube videos?

No. This tool only converts files already on your device that you have the right to use. It doesn't download from websites, and it can't process copy-protected (DRM) media.

Why is conversion slower than desktop software?

Everything runs in a single browser thread for privacy and compatibility, without the hardware acceleration desktop apps use. For long or 4K videos, desktop tools like HandBrake are faster.

What's the maximum file size?

500 MB. The browser holds the whole video (and the result) in memory, so very large files can fail, especially on phones. Trim long videos first.

Are my videos uploaded?

No. The converter runs on your device, so videos never leave it.

Stays on your device

Only convert videos you own or have permission to use. This tool works on files from your device; it can't download from YouTube or other websites, and doesn't bypass copy protection (DRM-protected files won't convert).

05Preview the result and download it.

About

What it does

Phones record MOV or HEVC files that some apps won't accept, screen recorders save WebM, and sometimes you just need the soundtrack or a short GIF. This converter turns your own video files into MP4, WebM or animated GIF, or extracts the audio as MP3 or WAV.

Conversion runs inside your browser with FFmpeg compiled to WebAssembly. Your video is never uploaded, which also means speed depends on your device. Short clips convert in seconds; long, high-resolution videos can take several minutes.

Supported formats

Input: MP4, MOV, WebM, MKV, AVI, M4V and most other common formats, up to 500 MB.
MP4 (H.264 + AAC): Plays on virtually every device, app and website.
WebM (VP8 + Vorbis): Open web format. Encoding it in a browser is slower than MP4.
GIF: Silent, looping, limited to 256 colours. Best for clips under 30 seconds.
MP3 / WAV: Extracts the audio track only.

Settings explained

Quality: Caps the height at 1080p, 720p or 480p and sets compression. Medium (720p) balances size, quality and speed.
Start / Length: Convert a section, e.g. start 1:05, length 10, to make a 10-second clip. Leave empty for the whole video.
Remove audio: Produces a silent MP4 or WebM, which is smaller and useful for background videos.

Good for

Converting iPhone MOV videos to MP4 for Windows or a website
Making a short GIF from a screen recording
Extracting the audio from a lecture or interview recording
Shrinking a video to 720p to share it
