Frequently asked questions
How do you shrink a video to an exact size?
The tool reads your video’s length, then computes the video bitrate that fits your target: (target MB × 8 ÷ seconds) × 0.9 as a safety margin, minus 128 kbps reserved for audio. It then re-encodes once with H.264 + AAC, so the result lands at or under your target.
Will compression reduce my video quality?
Some — fitting a long video into 16 MB always means trade-offs. Short clips compress beautifully; very long videos at tiny targets will look softer. If your file is already under the target, the tool tells you and skips re-encoding entirely.
What are the Discord, WhatsApp and email presets?
Discord allows 25 MB uploads, WhatsApp caps videos at 16 MB, and most email providers accept around 20–25 MB attachments. The presets encode those limits — or type any custom target size you need.
Does my video leave my device?
No. Everything happens in your browser: the analysis and the compression. The only download is the video engine itself (ffmpeg.wasm, an open-source build loaded unmodified from a CDN) the first time you compress a file. Your footage is never uploaded anywhere.
