Private by design
Compression runs in your browser. ToolJee does not need your video on a server to shrink it.
Preview first
Play the compressed clip before you save, so you only keep the version you like.
Works in the browser
No desktop install — open the page on a modern browser and start compressing.
Simple layout
One upload zone, clear presets, progress, then download. Built for everyday use.
Popular formats
Handles common phone and camera files such as MP4, MOV, WEBM, and MKV when your browser can decode them.
Why shrink a video?
Oversized clips fail uploads on Instagram, Facebook, YouTube, WhatsApp, or email. Reducing bitrate (and sometimes resolution) keeps the story intact while making the file easier to share. ToolJee’s compressor is aimed at that everyday job — not Hollywood color grading — so the controls stay short and practical.
You do not need editing experience: pick a preset that matches your goal (sharper look vs smaller attachment), compress, check the preview, and download the MP4.
How to reduce video size on ToolJee
- 1Add a video from your phone, laptop, or tablet. Very large files need enough RAM — if the tab struggles, try a shorter clip.
- 2Compress with Better quality, Balanced, or Smallest size. Watch the progress bar while FFmpeg runs locally.
- 3Preview & save the MP4 to your device. Keep the original if you may need full quality later.

Frequently asked questions
How do I keep quality high?
Use the “Better quality” preset. Smaller presets trade more quality for size.
Which formats are supported?
MP4, MOV, WEBM, MKV, AVI and similar formats your browser can play. Output is usually MP4 for compatibility.
How do I get a file small enough for email?
Pick “Smallest size,” or shorten the clip first and compress the shorter version.
Can I see the result before downloading?
Yes. After compression you can play a preview, then save only if you like it.
Do I need an account?
No. Compression is free in the browser with no sign-in.
Does it work offline?
You need the page and compression engine loaded once; processing itself stays on your device.
Can I use it on mobile?
Yes on modern phones, though large files are smoother on desktop because of memory limits.
Can I restore the original quality later?
No. Compression permanently reduces detail — always keep your original file.
