Convert videos to MP4, WebM, MOV or MKV
The video converter changes the container and, only when it has to, the codec. If the video already fits the new format, the streams are copied, so MKV to MP4 and MOV to MP4 usually finish in seconds with the original picture. Find your file type below.
| Your file | Convert to MP4 | What happens |
|---|---|---|
| MKV | MKV to MP4 | H.264, HEVC, VP9 and AV1 are copied |
| MOV from an iPhone or QuickTime | MOV to MP4 | H.264 and HEVC are copied, ProRes is re-encoded |
| WebM | WebM to MP4 | VP8, VP9 or AV1 become H.264 with AAC |
| AVI | AVI to MP4 | DivX and Xvid are re-encoded to H.264 |
| WMV | WMV to MP4 | Windows Media video and audio are re-encoded |
| FLV | FLV to MP4 | H.264 is copied when possible |
| 3GP | 3GP to MP4 | Old phone video and AMR audio are re-encoded |
| TS from OBS or a TV tuner | TS to MP4 | Remuxed when the codecs fit |
| MP4 with HEVC | HEVC to H.264 | Re-encoded for older PCs and TVs |
Compress a video to a size in MB
Type the size you need into the video compressor, or a percentage, and it shows the estimated result before encoding. Presets cover the common caps: compress video to 10 MB for upload forms, compress video for Discord (20 MB on a free account), compress video for WhatsApp (16 MB) and compress video for email (25 MB in Gmail).
Trim, split and merge clips
The video trimmer keeps the part between two handles. Its Instant mode copies the video without re-encoding, so a two-hour recording trims in seconds; Frame-accurate mode re-encodes for an exact cut. Split video makes equal parts or pieces every N seconds, and merge videos joins clips with optional crossfades.
Crop, resize, rotate or go vertical
Crop video removes black bars or snaps to 9:16, 1:1 or 4:5. Resize video sets a resolution or fits TikTok and Reels frames with blurred padding, and 4K to 1080p downscales big camera files. Rotate video fixes sideways clips through metadata, flip video un-mirrors selfies, and the horizontal to vertical video converter turns 16:9 into 9:16.
Change speed, reverse or loop
Speed up video anywhere from 0.25× to 4× while voices keep their pitch. The slow motion video maker blends frames for smoother motion, and the timelapse video maker runs long recordings 2× to 32× faster. Reverse video plays a clip backwards, the boomerang video maker bounces it forward and back, and loop video repeats it without re-encoding.
Edit the audio track
Remove audio from video drops the soundtrack and copies the picture untouched. Increase video volume by up to 20 dB, with a limiter against clipping. Extract audio from video saves the sound as MP3, M4A, WAV, FLAC or Opus (MP4 to WAV gives editors uncompressed PCM), and add music to video mixes in or replaces a soundtrack.
Add text, logos, blur and color
Add text to video places a styled title for a chosen time range, and add watermark to video stamps a logo on a whole batch. Blur part of video hides faces or number plates, remove logo from video fills in a date stamp, and video color correction applies filters or a .cube LUT. Shot against green? Remove green screen from video swaps the backdrop for a color, picture or clip.
Grab frames, GIFs and slideshows
Video to JPG exports a frame every few seconds, a fixed number of frames or all of them. Screenshot from video saves the one frame you scrub to at full resolution. Video to GIF shows the GIF size before it renders, and the slideshow maker turns photos into a video with music.
Fix broken, shaky or grainy footage
Repair video rebuilds the index and timestamps of a file that will not play, then remuxes it. Stabilize video (Beta) calms handheld shake, and denoise video cleans low-light grain. For full control of codec, bitrate and keyframes, the advanced encoder can also change video frame rate.
Video tools FAQ
Can I edit a video online without uploading it?
Yes. Each tool opens the file in your browser and processes it on your own device, so the video never reaches a server and there is no upload wait. A tool keeps working offline once it has loaded.
Is there a free video editor without a watermark?
Every tool here is free, needs no account and adds no watermark. They are single-job tools, not a timeline editor; to chain several edits, describe them to the AI video editor (Beta).
How do I edit videos on a Chromebook?
Open a tool in Chrome on the Chromebook and drop a video from the Files app. ChromeOS supports the same WebCodecs engine the tools use on Windows and Mac, and results land in Downloads.
Which video format is best for sharing?
MP4 with H.264 video and AAC audio plays on almost every phone, TV, browser and editing app. HEVC files are smaller (the compressor gives HEVC about 35% less bitrate for the same resolution), but some older PCs and TVs cannot play them.
How do I make a video smaller without losing quality?
Every re-encode loses some detail, so spend it where it shows least: match the resolution to the screen it will be watched on and pick HEVC if the viewer can play it. If only the format is wrong, a remux leaves the picture untouched.
Is there a file size limit?
No fixed limit. Files are read from your disk in chunks rather than loaded whole, so multi-gigabyte videos work on a laptop. On a phone, free memory is the practical limit for very large files.
