About Video Size-Limit Compression
Different platforms enforce strict upload limits, such as 8MB for Discord or 25MB for email. This tool estimates bitrate from your target size and video duration, then compresses the file directly in your browser so your videos stay on your device.
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; a ten-minute video may take 5-15 minutes. Closing other browser tabs frees memory and speeds things up.
Does compressing a video lower its quality?
Some loss is unavoidable when reducing file size. The tool lowers bitrate to meet your target, so a 10-minute video squeezed to 8MB gets roughly 100 kbps and looks soft at 1080p. Choosing 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 from 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 your target size like 10MB or 50MB, choose the file, and the compressed video downloads straight from your browser.
Compress video
Re-encode with a lower bitrate or resolution. Check playback, sound and the final size; a strict target may need further adjustments.
There is no guaranteed saving or exact target for every file. If the result is larger, some tools return the original; compare its format and size before sharing.
