Questions

Is Compress Video free?
Yes. Compress Video is completely free, no account, no sign-up, no usage limits, and no watermark. It runs entirely in your browser.

Is there a file size limit?
There's no hard size limit. Because Compress Video works locally instead of uploading, the practical ceiling is your own device's memory rather than any server quota, most everyday clips process without a problem.
