Convert, compress, trim and rotate videos, make GIFs or remove the sound. Everything runs in your browser, so your videos are never uploaded.
Drop the file onto the page, paste it, or click to choose. Nothing is uploaded — the video is read directly from your device.
Pick the format, quality or range you need. The sensible defaults work for most videos.
Processing happens in your browser. When it is done, save the new file — or all files together as a ZIP.
MPEG-4 Part 14
The universal video format
MP4 is the most widely used video format, usually with H.264 video and AAC audio. Phones, cameras, websites and social networks all use it.
QuickTime File Format
Apple's QuickTime format
MOV is the QuickTime format used by iPhones, Macs and professional editing software. It often contains H.264, HEVC or ProRes video.
WebM (VP8/VP9 + Opus/Vorbis)
The open web video format
WebM is a royalty-free format by Google with VP8, VP9 or AV1 video and Opus or Vorbis audio, built for the web and HTML5 video.
Matroska Video
The flexible all-in-one container
MKV (Matroska) can hold almost any video and audio codec plus several audio tracks, subtitles and chapters in a single file.
Audio Video Interleave
The classic Windows video format
AVI (Audio Video Interleave) was introduced by Microsoft in 1992 and was the standard for DivX and Xvid videos for many years.
Windows Media Video
Windows Media Video
WMV is Microsoft's video format from the Windows Media Player era, still common in older recordings and presentations.
Flash Video
The old Flash video format
FLV was the video format of Adobe Flash and early YouTube. Since Flash was discontinued, almost nothing plays it any more.
Apple MPEG-4 Video
Apple's MPEG-4 video
M4V is nearly identical to MP4 and is used by iTunes and the Apple TV app. Purchased films may be DRM-protected.
3GPP Multimedia
The early mobile video format
3GP was designed for 3G mobile phones and is still found in recordings from older phones and dashcams.
MPEG-1 / MPEG-2 Program Stream
MPEG-1 and MPEG-2 video
MPEG files hold MPEG-1 or MPEG-2 video, the formats of Video CDs, DVDs and digital TV recordings.
Graphics Interchange Format
Animated images
GIF is an image format that supports short, silent, looping animations with up to 256 colors, popular in chats and social media.
Family clips, screen recordings and work videos never leave your device. There is no server copy to leak or delete.
No account, no watermark, no daily limits and no waiting queue. Only your device's memory sets the limit.
When the streams already fit the target format they are copied without re-encoding: done in seconds with zero quality loss.
No. PixNudge runs ffmpeg compiled to WebAssembly inside your browser. Your videos are read and written on your own device and never sent anywhere.
Up to 1 GB per file on computers and 200 MB on phones and tablets. The result has to fit in the memory of the browser tab, so very long 4K videos may fail on older devices.
Changing only the container (for example MKV to MP4 with H.264 video) takes seconds, even for large files. When the video has to be re-encoded, a computer processes roughly one minute of 720p video per one to three minutes; phones are slower.
You can open MP4, MOV, WebM, MKV, AVI, WMV, FLV, M4V, 3GP, MPEG, TS, OGV and animated GIF files, and save as MP4, WebM, MOV, MKV, AVI or GIF.
Yes, in current versions of Safari, Chrome, Edge and Firefox. Short clips work well; for long or high-resolution videos a computer is much faster.
