Compress video to 10MB
You can compress a video to under 10MB entirely in your browser. Drop the file below and it is re-encoded on your own machine to land under 10MB -- nothing is uploaded, there is no watermark or signup, and the result is measured rather than estimated.
2Add your file
Video, images and PDFs, all compressed on your own machine. No upload, no account, no watermark, no limit on how many files.
The same tool takes video, images and PDFs, at this size or any other.
Mechanism
How this works
Four steps, one of which nobody else does.
- 01
Your browser reads the file
Length, resolution, frame rate and bitrate come out of the container in a fraction of a second. Nothing is decoded and nothing is sent anywhere.
- 02
We work out what fits 10MB
Subtract what the audio needs, divide the rest by the duration, and drop the resolution if the remaining bitrate is too low to still look like video.
- 03
Your own hardware encoder runs
The same silicon your phone uses to record video, reached through WebCodecs. This is the part that would otherwise be an upload and a queue.
- 04
We measure the output
If it came in over 10MB, the bitrate is corrected by the observed error and it encodes again. This is the step almost every other tool skips.
Questions
Compressing video to 10MB
- How do I compress a video to 10MB?
- Drop the file into the tool on this page -- the target is already set to 10MB. The work happens in your browser on your own machine, so there is no upload, no queue and no account. The output is measured before you are given it, so it is genuinely under 10MB.
- Is that exactly 10MB, or approximately 10MB?
- Under it, and verified. The byte count of the finished file is measured and compared against the limit before anything is handed back, and if it came in over, it is done again. 10MB here means 10 decimal megabytes -- 10,000,000 bytes -- which is the smaller of the two readings a platform might intend, so it clears either.
- Will a long video still fit in 10MB?
- Up to a point, and you are told before spending the time. The budget is divided by the duration, so a longer clip gets a lower bitrate and the resolution steps down to match -- 1080p, 720p, 480p, 360p, then 240p. If not even 240p fits, the page tells you how short the clip would have to be instead of handing you something unwatchable.
- Does it put a watermark on the video?
- No, and it never will. Compression runs on your own hardware, which costs us nothing per file, so there is nothing to ration and no paid tier to push you toward. No watermark, no signup, no daily cap.
