About Video Size-Limit Compression
Different platforms enforce strict upload size limits. This tool calculates bitrate from your selected size limit and video duration, then compresses videos directly in your browser. No server upload is required. Whether you are optimizing assets for a US-hosted site on AWS, Cloudflare, or Vercel, trimming email attachments for Gmail and Outlook, or submitting documents to federal portals, this tool keeps your files lean and your workflow fast — all without uploading anything to a server.
How to Compress a Video to 8MB, 25MB, or Any Size
Upload your video
Add one or more video files from your device. MP4 and WebM give the most reliable in-browser compression results.
Choose a size profile
Pick a preset such as Discord 8MB, Discord 10MB, Email 25MB, or enter a custom size and output format.
Compress and download
Let the browser encode your video and then download the result once the target is reached or the best possible size is produced.
Frequently Asked Questions
Can I compress a video to 25MB for Discord or email?
Yes. Choose the closest preset or enter a custom size target, and the tool will try to fit the output to that limit.
Will the tool always hit the exact target size?
Not always. Browser codec support, source quality, and duration can affect the final result. When an exact match is not possible, the tool returns the closest best-effort output.
Which video formats work best?
MP4 and WebM are the most reliable formats for browser-based compression. Some browsers can also open MOV files, while support for AVI, MKV, and older codecs varies.
Is this video compressor private?
Yes. Video compression happens locally in your browser, so your files are not uploaded to our servers.
How long does it take to compress a video?
Processing runs locally, so speed depends on your CPU. A one-minute 1080p clip typically finishes in 30-90 seconds on a modern laptop, while a ten-minute video may take 5-15 minutes. Closing other browser tabs frees up memory and speeds things up.
Does compressing a video lower its quality?
Some loss is unavoidable when reducing file size. The tool lowers the bitrate to hit your target, so a 10-minute video squeezed down to 8MB ends up at roughly 100 kbps and looks soft at 1080p. Picking a 480p or 720p resolution keeps the result watchable.
What is the maximum video size this compressor can handle?
There is no upload, so the limit comes down to your device's RAM. Files up to about 2GB generally process fine on computers with 8GB of memory or more. Very long recordings, like hour-long 4K clips, may need a machine with 16GB.
Do I need to install software to shrink a video?
No installation is needed. The compressor runs entirely in Chrome, Firefox, Edge, or Safari on Windows, Mac, Linux, and Android. Open the page, pick a target size like 10MB or 50MB, choose your file, and the compressed video downloads straight from your browser.
