About these tools
Video is now an everyday format: phone clips, tutorials, recorded meetings, social media content. But files are large, not always in the right format, and you often need just one part of them or a version fitted to a platform.
These tools use WebCodecs, the video encoding technology built into modern browsers, and the open source Mediabunny library to read and write MP4, MOV, WebM and MKV files. The work happens on your device, often with GPU hardware acceleration: no video is uploaded, which matters for family footage or business recordings.
There's no watermark, no account and no duration limit set by the site: only your device's power matters. A recent computer processes a video faster than real time; an older phone may need a little patience for long videos.
Which tool should I use?
Send a video that's too large
“Video compressor” cuts file size by 50 to 90% by lowering the bitrate and, if needed, the resolution: the fix for WhatsApp, email or size-limited forms.
Keep only one section
“Video trimmer” saves only the part between a start and an end point, set with the player.
Fit a social network
“Video resizer” switches to 1080p, 720p or 480p, or to square and vertical formats for Instagram, TikTok and YouTube Shorts.
Change format
“Video converter” turns an iPhone MOV into MP4, or produces WebM, MOV and MKV. “Rotate video” fixes a video filmed sideways.
Get the sound
“MP4 to MP3” and “Extract audio” save the soundtrack as MP3, M4A or WAV: a clip's music, a talk recording, a filmed voice note.
Make an animation or images
“Video to GIF” and “Video to animated WebP” turn a clip into a lightweight animation. “Video frame capture” saves one exact frame or a series of frames as JPG or PNG.
Frequently asked questions
Are my videos uploaded to a server?
No. They're read and processed by your browser, on your device. Nothing is uploaded, not even to our servers.
Which formats are supported?
Input: MP4, MOV, WebM and MKV with the most common codecs (H.264, HEVC depending on the device, VP8, VP9, AV1). AVI isn't supported.
Which browser should I use?
A recent version of Chrome, Edge, Safari or Firefox. Chrome and Edge on desktop are the fastest and support the most codecs.
Is there a length limit or watermark?
No watermark and no limit set by the site. For very long videos on a phone, the device's memory may become the limit.
