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.
