Will compressing a video make it look bad?

It will look a little softer. CRF 23 is close for ordinary viewing. CRF 32 is visibly mushier on text and grass. Keep the camera file if you might recut. This download is the sending copy, not a new master. Compare both on the same screen before you delete anything.

Can I set an exact target size in megabytes?

Not on this page. CRF aims at a quality level, not a byte count. Motion-heavy clips stay larger. If a form demands exactly 8MB, try Smaller plus a 480p cap, or use a desktop two-pass encoder. A fake target slider here would miss and still re-encode.

Will this video compressor work on iPhone or Android?

Yes, in Safari or Chrome, for short clips. Re-encoding 4K can exhaust phone memory and heat the device. Prefer a computer for anything past a few minutes.

Does compression remove the audio?

No. Audio is re-encoded as 96kbps AAC. Speech stays clear. Music loses some air. If you wanted silence, use the mute tool. If you wanted only the soundtrack, extract audio rather than compressing the picture you will not send.

How much smaller will my compressed video get?

It depends on the source. A 4K phone clip often drops 70 to 90 percent at Balanced with a 720p cap. An already-compressed 720p export may only shrink a little. Check the download size against the original before you delete the camera file.

Is it legal to compress a video I do not own?

Compressing a clip you recorded or have permission to send is the intended case. Re-encoding someone else's film to sneak it under an upload cap does not become lawful. Videozify does not store files and cannot check those rights.

A video compressor re-encodes a clip so the file is smaller for email, chat, or upload limits. Pick a quality preset, optionally cap height at 720p, and download an H.264 MP4 that fits a 25MB mail cap.

How to compress a video online

Drop a video file onto the box above, or click Browse to choose it from disk.
Choose Balanced, Smaller, or Higher quality, plus an optional height cap from the menus.
Press Compress and wait until the progress bar reaches one hundred percent.
Download the MP4 when it appears. Compare the new size before you delete the original.

Why compress a video online?

A video compressor trades bitrate for file size so a clip will actually send. iPhone 4K60 fills a gigabyte before lunch. WhatsApp, Gmail, and LMS uploaders bounce those files. You need a smaller copy that still plays on the other end.

This page re-encodes to libx264 with an ultrafast preset so a browser tab can finish. CRF 23 is the higher-quality choice, 28 is balanced, 32 is the small file. Capping height at 720p or 480p shrinks pixels before bitrate even starts. Audio becomes 96kbps AAC.

You will lose some picture detail. That is the point. Keep the camera original if you might recut. The download is the sending copy. If the clip is two hours, trim first. Compressing a lecture you will never watch whole wastes RAM.

This is not a target-byte encoder. CRF is quality-based. Two clips of the same length can still differ in megabytes because motion and grain cost bits. If you need an exact 8.00MB, a desktop two-pass tool is still the honest choice.

If you only needed a section, trim the video first. iPhone clips that already play everywhere may only need MOV to MP4 without this re-encode.

A video compressor is an encoder that re-writes a clip at a lower quality target so the file is small enough to send.

Which quality preset should you pick?

Balanced (CRF 28) is the default for chat and email. Higher quality (CRF 23) stays closer to the source and is still usually smaller than a raw 4K camera file. Smaller (CRF 32) is for a stubborn 10MB cap. Softness shows first on text and foliage.

Cap height when the source is 1080p or 4K and the destination is a phone screen. 720p is enough for most WhatsApp views. 480p is the last resort. Do not cap a 360p clip at 720p. That is upscaling, not compression.

Screen recordings of UI text suffer more than talking-head video. If the slides must stay sharp, try Higher quality and 720p rather than Smaller at full 4K.

Should you trim before compressing?

Yes, if you only need a minute. Compressing twenty unused minutes is how phone tabs die. Trim, then compress the leftover. Mute first only if the soundtrack is the waste. Silence does not shrink H.264 as much as people hope.

Already-small social downloads rarely need this page. Compressing a 4MB meme can make it uglier without a useful shrink. Check the size before you drop.

A 4K screen recording of a spreadsheet compresses worse than a talking head. Text edges ring. Prefer Higher quality and a 720p cap for UI, and accept that a 10MB form may still bounce a busy desktop capture.

Conference recap videos are the honest use case: forty minutes filmed, three minutes posted. Trim to the highlight, compress at Balanced and 720p, and keep the camera file on disk in case someone asks for the full talk later.
