Three simple steps. No account, no watermark, no waiting in a queue.
Drop any MP4, MOV, MKV, AVI or WebM file into the box above, or tap Choose File on mobile.
Choose a compression level or an exact target size in MB, adjust resolution, frame rate and audio, or switch to the Video to Audio tab.
Watch the live progress bar, preview the result and download your compressed video or MP3 instantly.
Powerful features that usually require desktop software, available free on any device.
Your videos are processed instantly on your own device and are never collected, stored or shared. Nothing ever leaves your hands.
Need exactly 25 MB for WhatsApp or 10 MB for email? Enter the number and the compressor calculates the right bitrate automatically.
Pull the audio out of any video as MP3, M4A or lossless WAV. Choose bitrate, sample rate and even boost quiet audio up to 3x.
Cut out just the part you need, downscale 4K to 1080p or 720p, lower the frame rate, or strip the audio track entirely.
Fully mobile optimized. Compress videos on Android, iPhone, Windows, Mac or Linux with the exact same experience.
No watermark, no daily limit, no sign up, no hidden trial. Professional grade H.264 compression at zero cost, forever.
See the expected output size for every compression level before you start, so you never have to guess or compress the same video twice.
MP4, MOV, MKV, AVI, WebM, 3GP, M4V, WMV, FLV and TS all work. Output plays everywhere as standard MP4, MP3, M4A or WAV.
This video compressor reduces the file size of MP4, MOV, MKV, AVI, WebM and 3GP videos using the same H.264 encoder trusted by professional editing software. Unlike most online tools, all processing happens instantly on your own device, so your personal videos are never collected, stored or shared. That makes it safe for family clips, work recordings, lectures and anything else you would not hand to a stranger.
Messaging apps and email providers have strict size limits: WhatsApp works best under 64 MB, Discord free accounts allow 25 MB, and most email services stop at 20 to 25 MB. Turn on Target size mode, type the limit, and the tool computes the exact bitrate needed to hit it. Combined with 720p or 480p scaling you can shrink a phone video by 80 to 95 percent while keeping it perfectly watchable.
The Video to Audio tab extracts the audio track from any video file, which is perfect for saving music, lectures, interviews, podcasts or voice notes. Pick 320 kbps for maximum quality, 192 kbps for everyday listening, or 96 kbps for compact voice recordings. You can also trim only the section you need and boost quiet audio up to three times its original volume before exporting to MP3, M4A or WAV.
Modern phones record at very high bitrates to be safe, which wastes a lot of space. Re-encoding with a tuned constant rate factor removes data your eyes barely notice: a typical 100 MB phone clip becomes 10 to 20 MB at 720p with almost no visible difference. For long videos, lowering the frame rate from 60 to 30 fps and reducing audio to 96 kbps saves even more without hurting the viewing experience.
All tools work instantly on your device, private by design.
Add your video above, pick a compression level such as Balanced, and press Compress Video. The tool re-encodes the file on your own device and gives you an instant download. There is no sign up, no watermark and no file limit.
Yes. The tool is private by design: all processing happens instantly on your own device and your videos are never collected, stored or shared. You can even turn off the internet after the engine loads and it will keep working.
MP4, MOV, MKV, AVI, WebM, 3GP, M4V, WMV, FLV and TS files all work. Compressed videos are exported as universally compatible MP4 (H.264), and audio can be exported as MP3, M4A or WAV.
Switch to the Video to Audio tab, add your video, choose a bitrate like 192 kbps and press Extract Audio. You can also trim only the section you need, change the sample rate, or boost the volume before downloading.
Turn on the switch that says Compress to a target file size, type 25 in the MB box and press Compress Video. The tool calculates the exact video bitrate needed for your clip length so the result lands at or just under the limit.
On first use the tool loads a professional compression engine of about 25 MB. It is cached after that, so future compressions start immediately. The page itself stays lightweight because the engine only loads when you actually use it.
There is no hard limit, but because everything runs on your own device, available memory matters. Files up to about 500 MB work well on most modern phones and computers. For bigger files, trim the clip first or use a desktop device.
Compression always trades some quality for size, but at the Light and Balanced levels the difference is nearly invisible for typical phone videos. Use Strong or Extreme only when the smallest possible file matters more than perfect sharpness.
