Video Compressor: shrink MP4, MOV and WebM to a size that fits

Give it a target size and it hits it. Two-pass encoding works out the right bitrate for your footage, then the result is measured and corrected so the file lands under your limit instead of near it. No account, no watermark and nothing to install.

  • Target an exact size, or pick a quality preset
  • MP4, MOV and WebM up to 500 MB or 30 minutes
  • Your upload is deleted the moment the encode finishes

Why the target size actually holds

Most online compressors guess a bitrate once and hand you whatever comes out. This one measures and corrects, which is the difference between "about 25 MB" and "under 25 MB".

1

Two-pass encoding

The first pass analyses your footage and the second spends the bitrate where the picture needs it. Still shots get less, fast motion gets more.

2

Measured, then corrected

Two passes alone often land several percent under target. The output is measured and the encode is repeated once with a corrected bitrate, so you get close to your limit without ever crossing it.

3

Impossible targets are refused

Ask for 5 MB from a 20-minute video and it says no, and tells you the smallest size that is actually achievable — instead of handing back an unwatchable file.

4

Quality presets too

If you do not care about an exact size, choose High, Medium or Low. Each shows an estimated output size before you start.

5

Optional downscaling

Keep the original resolution or drop to 1080p, 720p or 480p. Lowering the resolution is often the cheapest way to reach a small target while keeping the picture clean.

6

Standard MP4 out

H.264 video with AAC audio and fast-start enabled, so the file plays everywhere and starts immediately when streamed.

Four steps to a smaller file

1

Upload the video

Drop in an MP4, MOV or WebM. The file is inspected with FFprobe, so anything that is not really a video is rejected before any work starts.

2

Pick size or quality

Type a target in MB, or use a preset: 8, 16, 25, 50 or 100 MB. The tool shows the smallest size your clip can reach.

3

Choose a resolution

Keep the original or scale down. The aspect ratio is preserved automatically and the video is never scaled up.

4

Compress and download

Watch the progress bar, preview the result in the page and download it. Your upload is deleted as soon as the encode finishes.

Which videos you can compress

MP4

Phone and camera video

The default recording format on almost every phone and camera.

MOV

Apple recordings

QuickTime files from iPhones, iPads and Mac screen recordings.

WebM

Browser and screen capture

Common output from browser recorders and open-source capture tools.

Limits. Up to 500 MB and 30 minutes per file, and three videos per hour per visitor. At most two encodes run at once and anything else waits briefly in a queue. Video encoding is expensive, and these limits are what let the tool stay free.

When a hard size limit is the whole problem

Chat and email attachments

Most messaging apps and mail servers stop at 25 MB. Set that as your target and the file will fit on the first try.

Bug reports and support tickets

Issue trackers cap uploads at 10 MB or so. A short screen recording compresses well below that at 720p.

Course and portal uploads

Learning platforms often enforce a fixed limit and reject anything above it without explaining why.

Saving storage and bandwidth

Screen recordings are enormous for what they contain. Compressing them before archiving costs nothing in visible quality.

A compressor, not an editor

This tool changes file size, and that is all. It does not trim, crop, rotate, merge, add subtitles or change the audio. If you need to cut a section out first, use the video cutter and compress the result afterwards.

Compression is lossy by definition. Ask for a very small target from a long or highly detailed video and the picture will soften — that is arithmetic, not a bug. When a target would push quality below anything usable, the tool refuses it and tells you the smallest size that still works.

Video compression FAQ

Will the output really be under my target size?

Yes. The encode is measured after it runs and repeated once with a corrected bitrate if it landed outside the band. Overshooting the target is treated as a failure, so the tool always errs on the small side.

How much quality will I lose?

It depends entirely on how far you are compressing. Halving a file is usually invisible. Cutting a 200 MB video to 8 MB is not, and dropping the resolution will look better than keeping it at that size.

Should I lower the resolution?

If your target is small, yes. A clean 720p file beats a blocky 1080p one at the same size. For screen recordings with text, keep the resolution and accept a larger target instead.

Is there a watermark?

No. The output is a plain MP4 with nothing added, and the file name contains no tracking of any kind.

What happens to my video?

The upload is deleted immediately after the encode finishes and the compressed result is removed an hour later. No account, nothing stored.

Why is there an hourly limit?

Encoding video is by far the most demanding thing on the server. Three videos per hour keeps the tool free and responsive for everyone rather than fast for one person and unavailable for the rest.
